Intelligent Power Module (IPM) board has been designed using FSBS5CH60 IC from Fairchild, which provides a fully-featured, high-performance inverter output stage for AC Induction, BLDC, and PMSM motors. These modules integrate optimized gate drive of the built-in IGBTs to minimize EMI...

Lots of op-amp based circuits require dual (symmetrical) power supply. This tiny circuit is a simple solution which provides +/-12V DC 300mA from single 5AV DC   input. The board is based on LM2588-ADJ IC from Texas instruments. Step up from 5V to dual 12V is the best part of the...

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,...
