How to use this relay with 4 wires Chapters of this video Home appliances controlled by Dark Sensor 5. Share it with us! The HC-05 zs-040 modules have a voltage regular on then vcc in line. Hi I wanted to build a simple 2 channel bluetooth remote switch box. You will hear the click sound as there state changes from OFF to ON or from ON to OFF. Did you make this project? In this illustration we will going to wire the HC-04,HC-05 or HC-06 module using serial communication with our Arduino board and 4 channel relay, we will going to control the relay on the Android smart phone or tablet via Bluetooth to control the relay remotely. (You can be modification Arduino code and connections.) 4. If you want to know more about the relay module, you can check this article “ Arduino relay Code, connection and control “. How i wired my componnents i have shown in blow pic. 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. 4 years ago, please send the skecth to my email ilhambintang559@gmail.com, I have a questiin you may can help with i do heating and air have a unit that has bad tstat wire going from indoor to outdoor unit so it wont allow anything outside to kick on and cant run new wire its not possible is there any bluetooth relay i can build so when thermostat calls for ac it will send signal to od unit and close a relay to allow 24 volts to contator i can put a transformer out there to. For this project, I am using 2 channel relay module. The code is attached in the end of this project. be careful when purchasing the bluetooth module and check that its the board and bluetooth chip. I wanted to be able to control it from my android phone. Arduino Forum > Using Arduino > Programming Questions > Nodemcu and bluetooth and 4 channel relay; Print. The Arduino can be programmed to turn on the 4 channel relay module when a certain event occurs, for example when the temperature of a thermistor gets higher than 30° C. Or when the resistance of a photoresistor drops below 400 Ohms.
