This project, done incorrectly, could certainly burn down your house. All the usual warnings apply: Main voltage (120VAC or 220VAC) can kill you. Note that the distance between digital pins 7 and 8 is 160 mil (0.16"), not an even multiple of the 100 mil spacing of the other pins. In this tutorial we will discuss a small relay board to control the power to a normal AC outlet using 5VDC control. How To Use and connect arduino with 5V 8 Channel Relay Module thank you for watchingMore videos. Four screw holes allow the Shield to be attached to a surface or case. 1) Take a jumper (dupont cable) and connect one end to PIN 7 of Arduino. The maximum length and width of the 4 Relays Shield PCB are 2.7 and 2.1 inches respectively. Step 1: Wiring Arduino and the relay board. 5 volt relay (i used 6 volt because i need 6 volt relay) 2. here the list of all the parts you needed to do this project: HARDWARE: 1. NOTE : Most of the parts was lying around my home,I used to save little more ยข. Both connect to the same TWI interface to allow you to create a chain of TWI devices. Now we need to collect some parts that we needed to make the Diy relay module. Click Upload button on Arduino IDE to upload code to Arduino. Copy the above code and open with Arduino IDE.
