This H-bridge i`m using now for my Sumo-bot ( This H-bridge )I think is fairly good for medium size motors ( untill 30A peak and 13 A continuous mode). The price is arround $75 plus sending. We start talking about what is a "H-bridge". One H-bridge is a.... -
A bidirectional H bridge DC motor control circuit is shown here. The circuit is based on the IC L298 from ST Microelectronics. L298 is a dual full bridge driver that has a wide operating voltage range and can handle load currents up to 3A. The IC also.... -

4QD manufacture motor speed controllers so all our H bridges are PWM. Here`s a simple switch circuit for reversing and stopping a motor without any control of speed. Two inputs, A and B, control the bridge. With both high (or open circuit) both ends of the.... -
I made an hbridge using TPS2836 and CSD16404. The schematic is shown below. It does not work properly and I have a few questions about it. It would be great if you can point out where the design is wrong. 1. I gave a VDD-GND of 5V and tried to give the.... -
H-bridge is a circuit configuration that allows the designer to apply the voltages in both directions. H-bridge also allows higher voltage and current to be applied to the load while controlling the direction through a low voltage signal. The illustration.... -
An H bridge is a kind of circuit you use to control the direction (and sometimes speed) of an electric motor, using only a single polarity voltage (you need to reverse the way current flows in order to reverse the way the motor rolls). You have 4.... -
Using this(also below in question) circuit to drive a motor, and I heard I should put a decoupling cap in there to smooth out voltage spikes. I have been told to put it close to the ic, and I have also been told not to put it in front of the ic, but between.... -
Many electric cars are able to convert the momentum of the car into stored energy in batteries, rather than convert it to useless heat at the brake pads. How does this work How can I implement it myself Probably you already have it, and just didn`t know it..... -
The circuit given here is of a simple H bridge motor driver circuit using easily available components. H Bridge is a very effective method for driving motors and it finds a lot of applications in many electronic projects especially in robotics. The circuit.... -
The NJM3772 is a stepper motor driverwhich circuit is especially developed for use in microstepping applications in conjunction with the matching dual DAC (Digital-to-Analog Converter) NJU39610. The NJM3772 contains a Clock oscillatorwhich is common for both.... -
The TS4956 is a complete Audio system device with three dedicated outputs, one stereo Headphone one loudspeaker drive and one mono line for a hands-free set. The stereo Headphone is capable of delivering more than 25 mW per channel of continuous average.... -
We use the L293D H-Bridge to operate a 12VDC motor with the Arduino. This H-Bridge allows us to do several things. First it allows us to interface the motor, which requires much more current and voltage than the output pins can supply, with the Arduino. With.... -
You might find yourself needing a low power H bridge for driving a motor like I once did. The 555 IC can drive a load up to 200mA, source or sink, which might make is usable as a driver, if one can control the output as desired. Although it is an unusual use....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
