Arduino 8 Relay Module Wiring

5v 1 channel relay module.

Arduino 8 relay module wiring. This is a 5v 8 channel relay interface board be able to control various appliances and other equipment with large current. To test wire it up i ran arduino 5v to vcc on the main block arduino earth to gnd on the outer smaller block digital pin 9 to a in1 also tried other in pins i set the arduino to pinmode thispin output. Now i assume the jumpers allows the relay module to take power from the vcc of the main pin block. Learn how to use relay with arduino how relay works how to connect relay to arduino how to code for relay how to program arduino step by step.

3 3v 1 channel relay module. Since the arduino operates at 5v it can t control these higher voltage devices directly but you can use a 5v relay to switch the 120 240v current and use the arduino to control the relay. So connect the 5v and the ground of the arduino with the 5v and the ground of the relay module. The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino.

This 8 channel relay module can adopt most common range of microcontrollers such as arduino raspberry pi avr pic arm with digital outputs to control larger loads devices like ac or dc motors electromagnets soleniod incandescent light bulbs actuators and any another devices that you want to drive with in the relay. In this example we will connect the relay module with arduino in the normally open state. Then connect the signal pin of the relay module with the pin 12 of the arduino. Arduino relay circuit and arduino relay code.

The six pins on the left side of the relay module connect high voltage and the pins on the right side connect the component that requires low voltage the arduino pins. The connections for connecting the relay module with arduino are very simple. It can be controlled directly by micro controller raspberry pi arduino 8051 avr pic dsp arm arm msp430 ttl logic 5v 8 channel relay interface board and each one needs 15 20ma driver current. Relays are suitable for driving high power electronic devices such as lights electric fans and air condition.

The following figure shows the relay module pinout. In this video we ll learn how to use a sainsmart 4 channel 5v relay module with an arduino. 5v 8 channel relay module. We also discuss the.
