Arduino relay module – how to connect CAN & i2c relay board PoRelay8 and how it works?
Here is a practical example of Arduino driving i2c relay board as a arduino relay module. PoRelay8 board with 8 relay outputs can be connected to any Arduino device if it can communicate via the I2C protocol. If 8 relay outputs do not satisfy your demands, additional up to 9 PoRelay8 boards can be daisy-chained … Read more
