One of the advantages using the Microchip PIC microcontroller Pulse Width Modulation or PWM for short is; this PWM peripheral circuit is designed to control the DC motor using the full bridge mode PWM feature. The PWM peripheral works by supplying the correct signal to the H-Bridge DC motor circuit such as speed controlling and changing the DC motor direction.

Slide Show related to H bridge lecture. Higher quality Pictures. Links to schematic to come. ncfusion.com The measurements previously made for the motor start, run (no load), and stall current help determine both the semi-conductor devices and the resistors. When saturated using the more efficient PWM, rather than linear, bias of the transistor about any TO 220 package can handel the job but check the specifications, datasheets, and application notes. The addition of a heat sink was not necessary for our application but can help drive larger motors with heavy loads. Flyback energy will be examined for education purposes and helping choose diodes for inductive kickback. The 1N4000 series does a good job for this application. Note: Some transistors have diodes built in for inductive loads like motors and relays. Istart = peaked at 1.4Amps and decayed exponentially to a no load 100mA current over about 200ms. The stall current is 1.4A. A power supply should be able to handle 2-5amp in rush at 12V and steady current of an amp or two depending on the load. With the addition of a shunt resistor we will know if the motor is changing direction based on polarity. The current measured with the shunt can automatically fold back the current, and protect components and the power supply, along with the mechanics being driven with the motor.

This H Bridge Motor Controller with Optical Isolation can be operated with The SPST switches and simple digital electronics as shown. The circuit can also interface with a microcontroller like the Arduino. The On/Off switch and FWD/REV switch can be wired to discrete inputs on a micro (one input required for each switch), and then two outputs (one analog for on/off and speed and one digital out for forward/reverse). The On/Off switch is disconnected and becomes a PWM/Enable. The motor will be off when this analog (Pulse Width Modulated) output from the controller is not enabled or has a 0% duty-cycle (GND). The PWM is 8-bit for provide 255 steps, not counting off or disabled, and the PWM duty is proportional to the voltage and speed of the DC Motor. For example a 10% duty cycle will run the motor at 10%, and a 50% duty-cycle averages currents in the motor as half the voltage is applied. A 100% duty cycle or always on will run the motor at full power. The input for FWD/REV could stay put for basic logic, but we will run the switch in the controller and use a discrete output to command forward, as this will allow the system to grow. More on this circuit: ncfusion.com The prior design was similar to this but used two biased op amp comparators, and had simple logic. Just as this circuit it could stand alone or operate with a controller. BTW: The note on the board is to add the flyback suppression diodes, as the transistors we are using do not have them built in. We will also <b>...</b>

PWM Controlable H-Bridge Arduino forward & backwards large motor control www.andregoncalves.info An H-Bridge by definition its an electronic circuit which enables a voltage to be applied across a load in either direction. meaning that it can control devices like DC motors to spin in both directions. Using two pwm digital pins it creates an easy way to plug one large motor and control its speed and direction. Features: Selectable pwm outputs ( through two jumper cables you can control the h-bridge from any 2 pwm outputs) Optocoupled circuit which isolates the motor power supply from the the arduino.

First stage of creating a power supply for my h-bridges. This will convert +12V to +21V and +5V. I use the LM3524D chip for controlling the PWM to the step-up circuit. I use a small mosfet to get the PWM signal inverted, and then a power mosfet to invert (and boost) the singnal again. This will run at 16kHz. And I believe it will be able to output 1A at +21V. For the +5V I use a common TS7805CI. This will do 1.5A at +5V. I'm adding a lot of connectors so I will be able to connect at least 4 double h-bridges for my 4 axis CNC project.

This setup uses an Mindstorms NXT brick to communicate with the Mindsensors PCF8574A board. This IO expansion IC controls the dual H-Bridge chip, the L293D compatible SN754410. The breadboard has a direction and an enable/disable button. With these two buttons I can control in which direction the motor should turn and whether or not we should disable the motor altogether.

First low-level test of the H-Bridge I'm developing. The awesome NPC-2212, pulling 2A. I did some preliminary low-power testing with resistors, 200mA, 400mA, but this is the first that I did with the intended motor. 2A is a lot for breadboards, so there's probably some loss there, but the FETs are radiating. For the next installment I'll provide PWM, to slow it down, and likely some heatsinking for those MOSFETs. incredulist.blogspot.com
Precision Motion Control: An embedded computer controls a brushless 3-phase servo motor (Sanyo Denki BL Super P5) using three sections of a quad H-bridge. The motor also has a 2048 line encoder with an index pulse. Encoder pulses and PWM output are displayed on the oscilloscope. The high current power supply is a bridge rectified toroidal transformer fed by a variac (autotransformer) to set the voltage level. Employing USB connectivity, a PC software application written in C++ submits position and stop commands, receives and transmits I/O and receives encoder specified position. Submitted by AutomationPro in association with the University of California San Diego Extension. Thanks for watching.

A rough demo of my '01 EBMM Musicman Sterling with a piezo bridge and 3-band eq. Ideally, it might show a little of what the piezo option can do for the sound. (to me, it doesn't add 'treble' so much as adds 'presence' to the sound) Blend in to taste :) You might notice me fade the mic for the voice in and out when I start to play, altering the sound of the bass for a moment at the beginnings...sorry. It helps make sure you're hearing just the mag pickup, though... If this sucks, chalk it up purely to operator error on my part. It's a killer bass, and dead-stock.

SEGFAULT is a balancing vehicle with a 100% hardware stability controller. Not a single line of code runs to keep the vehicle upright. An analog complementary filter implemented with operational amplifiers combines the outputs of an accelerometer and rate gyroscope and passes it to a proportional-integral (PI) compensator. The output of the PI compensator has a steering offset differentially added to it. The resulting analog voltage is the input to two custom 24 volt, 30 amp locked-antiphase H-bridge drivers (Class D amplifiers), which control the two 27:1 geared, 500 watt drive motors. The vehicle frame is waterjet-cut aluminum and diamond-plate aluminum, and features a tiltable handlebar for steering input. Lastly, the P, I, and K controller gains are accessible and tunable by the user through a set of knobs on the handlebars. Segfault's page is here: www.etotheipiplusone.net For more information on the design and evolution of the controller, see www.etotheipiplusone.net specifically.

This is my first Arduino project and my first ever video. High Concept: Xbox360 Controller is used to control a RC Car. Nitty Gritty: A C++ program runs on a laptop. The program uses an input library called Object Oriented Input System found here, sourceforge.net/projects/wgois/. The program reads the input from the Xbox360 controller and sends simple data serially through the USB port to the Arduino. The serial library was found here, codeguru.com/cpp/in/network/serialcommunications/article.php/c2503. The car's original circuit board was ripped out and the Arduino was hooked up to the car's drive and steering motors. A dual H-bridge motor controller is used to control the motors. Future: - Supa Charge! Make this run off a RC Car battery rather than USB. - Go wireless using bluetooth - Add a wireless camera with pan and tilt functionality - Add siren leds that toggle on/off when I push a button on the Xbox360 controller

www.youtube.com As industry pioneers of 7 & 8 string guitars and extended range instruments for production models, Ibanez has always been on the cutting edge. Instead of focusing on the lower register, we've added higher notes, with an extended 30 fret fingerboard to create an extreme shredding machine! The rosewood fingerboard contains 30 Jumbo frets at the standard long scale length (25.5"). Also featured is an eye catching extra-deep cutaway that allows access to the higher frets effortlessly while retaining the beauty of an authentic RG body shape. Other key features include 5 screws All-Access Neck Joint with a smoother heel scoop for your thumb, which allows the maple neck to be firmly and seamlessly bolted to the resonant Alder body. This guitar is equipped with the famous Ibanez Edge-Zero tremolo with the Zero Point System, a recessed output jack and white DiMarzio® pickups. Furthermore, this guitar includes a special hidden feature. We didn't want to sacrifice the tone of a Neck pickup for the extra length of fingerboard. Instead, we retained the popular 5-way split switch, and developed a Neck Pickup Simulator Circuit powered by a 9v battery, specially designed for this extremely limited edition RG. This allows for the ultimate shredding machine without compromise!

After the tragic collision of the Arkendale H and the Wastdale H on the night of 25th October 1960 which resulted in the demolition of two spans of the Severn Railway Bridge I filmed the remains of the bridge which stood unrepaired until it was finally demolished in 1965. COMMENT: The demolition of this bridge has to be the worst transport decision made by transport chiefs at any time in Gloucestershire as today this link would provide a shorter route for diverted trains from the Severn tunnel than using Gloucester. It would also have provided a short rail link between the Forest and Cam and Dursley and Yate, Filton and Bristol. But the did save the taxpayer £85000 to rebuild pier 17. Subsequent demolition cost £2million.. Who employed these people???
