Detail about Relay Module 

4-CH digital relay module provide 4-CH input and output, Can connect Max. 30V 10A or AC 250V 10A devices to control electric lamp and electrical machine, etc; When using the Arduino do interactive projects, many large current or high voltage equipments cannot use Arduino digital IO port to control directly (such as solenoid valves, lights, motors, etc.), you can consider to use relay scheme to solve.
