This is an 8 channel infra-red remote-control Arduino shield that can drive 8 high current loads such as LEDs, solenoids, multiple toy DC Motors, dual unipolar stepper motor, filament lamps, etc. Each channel consists of two parallel NPN transistors with freewheel diodes which are important to drive inductive loads like motors. The shield consists of 2 x ULN2803 Chips, Infrared receiver TSOP1838, trimmer potentiometer, 4 tactile switches with pull-down resistors. The shield is compatible with Arduino UNO. Arduino code is also provided to test the shield. I have used a cheap IR remote to test this shield, this remote transmit NEC code but any other remote can be used with this shield and it will require to decode the remote switches.
