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....

This current sensor amplifier and over current switch project is based on ACS714-30A current sensor and LM358 OPAMP, ½ of LM358 op-amp used as an amplifier for low voltage  and 2nd 1/2 LM358 op-amp used as a comparator which provides over current TTL output, trimmer potentiometer...

The 6 Channel RF Remote Controller designed using CC2500 RF Transceiver modules and PIC16F1847 micro-controller from microchip. Transmitter provided with 6 tact switch, 4 Address Jumpers to pair multiple unit so they don’t interfere with each other. Board provided with power LED,...

Introduction Sometimes it may be necessary to use a display when making a hardware project, but one confusing thing is the size of the display and the required pins to control it. This tutorial will show you how to use a small I2C OLED display with Arduino using only two...

The pressure sensor amplifier built using LM358 op-amp and MPXM2051GS pressure sensor from NXP semiconductor.  The circuit provides 4V output for full scale pressure input 0-7.5PSI.  One op-amp is used as amplifier and 2nd op-amp is used as comparator to provide an output at set...
