DIY-CNC controlled by Arduino UNO GRBL 1. This makes it easy as Arduino can power up the relay directly. 4 Channel 5V Optical Isolated Relay Module This is a LOW Level 5V 4-channel relay interface board, and each channel needs a 15-20mA driver current. Available in one, four and eight channel versions, these modules can switch up to 10A per channel. Simple relay operation with Arduino This is a very simple sketch to show the operation of a relay.
