4 hannel 12V Relay Module 1. The Bluetooth module receives data from the paired Android smartwatch and triggers the relay based on the received data. It works in two different modes, Normally Open (NO) and Normally Closed (NC). This is the most important loop in the code. Relay module for Arduino is one of the most powerful application for Arduino as it can be used to control both A.C and D.C devices by simply controlling the relay by giving 5V. Several microcontrollers or microprocessors can be used for automating the appliances and when we integrate all these appliances through microcontrollers, it becomes very easy and low-cost to control all these appliances by giving just one command through your computer or any other device. 4.6 out of 5 stars 350. After we finish connecting the motor, all we need to do is power the relay switch module itself. U.R.Padmanabhan. #define LEDgreen 4 // Plug the Digital Pin 4 on Arduino to Green LED (+ 220 ohm resistor) and then to "NO" terminal on relay module.

So I am designing a simple project where my Arduino reads analog values from a potentiometer, or rotation sensor, as it is called on EBay, and uses that value to determine how many relays to close. Input 4 (IN 4): This will be connected to the digital pin on your Arduino, or leave it unconnected if you do not want to use this channel. The RX and TX pins of the Arduino connect to the TX and RX pins of the HC-06 Bluetooth module, respectively. Iron Core Bisa dilihat jelas pada gambar dibawah ini : Gambar bagian dari relay Pada gambar diatas dapat diketahui bahwa sebuah Iron Core atau inti besidiberikan lilitan kumparan Coil agar terciptanya atau timbulnya gaya elektromagnetik. Regards Thank you brilliant explanation. To connect the 4 Relay board to an Arduino is very easy and allows you to turn on and off an wide range of devices, both AC and DC. 4.The power source and the relay system power can be divided. Below is the list of components that we are going to use : Here, we are using a 4 relay module because we will only control four appliances. Then go to “Devices and Printers” and check the name of the port to which your Arduino is connected. Notify me of follow-up comments by email. When we will trigger the relay module then it will open the circuit, so the connection is lost. Take the positive wire of the appliance and cut it. You have just saved me hours of head scratching. Uses optocoupler driven relays to switch higher voltage and/or current applications with an Arduino, Raspberry Pi, Beaglebone, or other microcontroller or ARM boards.
