Snake Animation Is Used In The Proprietary LED Displays To Indicate Working, Busy. Arduino TM1637 Scrolling Text, Snake Examples.Notice in diagram how the two wires is cut and connected to the common and the normally open pin of the module output connector.Ĭoding part is like Arduino’s Blink snippet :Īrticles Related to Blink AC Bulb With Arduino Relay Module The Arduino’s 5V pin need be connected to the Vcc pin of the module and the pin number 13 (or some other pin) need to be connected with the In1 input pin for controlling the relay.
We will use a 5V Adapter as a separate power supply for this unit. There will be two things printed on DC connection side of relay module – JDVcc and GND. That property is used in decoration with colored bulbs – if alternative bulb is connected with COM and NO, that will look beautiful without working huge behind the circuit or programming. When we will programmatically trigger the relay module the connection will be lost. NO means Normally Open, which acts like a switch, When we will programmatically trigger the relay module, it will connect to COM and supply to the load is provided to power up the light.
