Introduction Sometimes it may be necessary to use a display while making a hardware project, but the size and the type of the display may vary according to the application. In a previous project, we used a 0.96" I2C OLED display, and in this project we will have an I2C 20x4 character...

This circuit is based on TPS54302, a high efficient buck converter from Texas instrument. The input range for this circuit varies between 4.5V to 28V and it can produce an output voltage of 5V. Over voltage protection and over current protection are the two major advantages of this...

New Version: A new version of the Sound to RC Servo is available "Sound to RC Servo Driver v2.0 – Arduino Compatible" This project is designed for Animatronics and Puppeteer applications, however, it can be used in other applications like sound-responsive toys, robots, etc....

Clap to light switch with timer project is very useful project for power saving applications. The project switches on the LED light for 45 to 60 seconds when receives two clap sound. This project can be used in store room, toilets, dark area where switch is not visible, night lamp,...

6V Lead acid (SLA) battery charger project is based on BQ24450 IC from Texas instruments. This charger takes all the guesswork out of charging and maintaining your battery, no matter what season it is. Whether you have a Bike, Robot,  RC Car,  Truck, Boat,  RV, Emergency Light, or...

Although the power supply design is specific to the Brushless Servo Drivers mainly for IPM Modules, the concepts and circuit design may be used for any power supply that requires high voltage output up to 400V DC and 5 Amps. The power supply is an unregulated design with an option to...

This compact board will help you to drive 4 Wheel Drive Robots, each axis can handle a load current up to 3 Amps and supply 12V – 48 V DC. Board requires two PWM and Dir. signals for full 4WD operations, mainly differential steering for taking turns left or right or complete 360...

This PIC development board has been designed to develop RS485 based and DMX512 applications, the board has 28 pin SMD Pic micro-controller, RS485 chip for communications, all I/O line has pull-up resistor which can be soldered as per application requirement on particular port pins....
