MP3 Shield has been designed for various applications related to voice record and play using MP3 module with memory card storage, this shield can be used as standalone mode or Digital mode by serial interface. In standalone mode it can play 16 messages with couple of other functions,...

Compact Unipolar stepper motor driver can drive unipolar motor up to 3.5A and supply range 10 To 50V DC. This compact board is based on STK672-440BN IC from ON semiconductor. The STK672-440BN is a hybrid IC for use as a unipolar, 2-phase stepper motor driver with PWM current control...

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...
