Overview
Its a two relay board circuit, normally used to control dc motors. As it has two relay on it so it can be used to control the direction of DC motor.
Components Used:
- Optocoupler (PC817)
- Transistor (C945)
- Resistors
- Capacitors
- Leds
- Diodes (4007)
- Relay (7A,250V AC - 12A, 120V DC)
Terminals:
It has 5 input terminals which are as follows:
- +12V
- +5V
- GND
- IN1
- IN2
IN1 and IN2 are +5V/GND signals coming from any microcontroller. IN1 controls first relay and IN2 controls second relay. I will post a tutorial on it soon and will add the link here. It has 6 pins on the output which are simply the relays output. Once can connect anything on it.
Compatibility:
Its compatible with all the below microcontrollers:
- Arduino
- Atmel
- PIC
- AVR
- NXP
- LPC
and any other microcontroller. I am gonna post its Arduino library real soon, so that user can use it easily.
