The code behind this is pretty.
Arduino android bluetooth relay control.
Pair your android with the bluetooth module connected to your arduino and.
You can use for control the arduino s pin13 pin12 pin11 pin10.
2 4 channel 12vdc relay card.
This code uses arduino s serial communication protocol with the bluetooth module.
The arduino bluetooth relay 4 channels app supports to control 4 channel relay module via bluetooth hc 05 hc 06 hc 07 ect modules.
How i wired my componnents i have shown in blow pic.
You can modify the arduino code and connections.
You can connect the bluetooth modüle on arduino s rx pin0 and tx pin1.
The bluetooth module receives data from the paired android smartwatch and triggers the relay based on the received data.
This uses a bluetooth module hc 05 connect.
The arduino bluetooth relay 4 channel app supports the control of a 4 channel relay module via bluetooth hc 05 hc 06 hc 07 ect modules.
5 jumper wires etc.
Now please can you provide me a sketch so that i can operate relay via my android mobile using arduino bluetooth control device android app.
You can be modification arduino code and connections.
This project consists of using an arduino a cheap bluetooth module and a relay to control for example a lamp by connecting it with your smartphone via bluetooth.
You can use the arduino s pin 13 pin 12 pin 11 and pin 10.
The arduino bluetooth module at the other end receives the data and sends it to the arduino through the tx pin of the bluetooth module connected to rx pin of arduino.
The android app is designed to send serial data to the arduino bluetooth module when a button is pressed on the app.
The rx and tx pins of the arduino connect to the tx and rx pins of the hc 06 bluetooth module respectively.
You can connect the bluetooth module on arduino s rx pin 0 and tx pin 1.
3 hc 05 bluetooth module.
Arduino remote control apps 1.
Arduino bluetooth relay 4ch app is android application which is used to control 4 channel relay module via bluetooth with bluetooth serial communication module support hc 05 hc 06 or hc 07 using arduino or avr i am test with arduino uno and serial commnunication library to connected rx pin 10 and tx pin 11.
This project is intended to be simple using the least amount of resources and code but still including important demonstrations and descriptions of the whole process.
4 arduino bluetooth control device android app.
From which you can make your home lights fan etc control with your phone.
Bluetooth hc 05 with arduino and relay this is a home automation project.
You can use arduino uno or arduino leonardo etc.
