Arduino relay wiring – how to connect Smart relay board PoRelay8
Here is a practical example of Arduino driving smart relay. 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 over CAN bus, even with long … Read more
