- all interfaces are available through a direct connection terminal leads
- very convenient
5V relay modules are devices that can switch high voltage or high current devices on and off using a 5V signal from Arduino. They can be used to control devices such as lights, fans, motors, solenoids, etc. 5V relay has three high voltage terminals (NC, C, and NO) which connect to the device you want to control. The other side has three low voltage pins (Ground, Vcc, and Signal) which connect to the Arduino.
