![]() The only difference will be, the pins will function only if that push button gives high input to the micro controller, else ignore them. To remove this, I decided to use another push button with same 1K pull down resistor. This maybe due to noise generated for some reasons. I can use a female header to connect with the standalone Arduino.Īlso I have planned to add another push button which will control the relay that will be used to turn on or off the main power supply for the device.Īfter using it for some hours, I noticed the speaker turns on/off automatically, switches to another mode on it's own or increases or decreases volume on it's own, meaning there was false triggering. It will be more practical instead of whole Arduino Uno and will be cost effective. In the other end, I again used male headers.įuture plans: I'm thinking to add a standalone arduino circuit to the assembly. instead of soldering wires to the LED, I decided to use female that can be removed easily. You can use your own idea for mounting the IR led to the device. The transmitter: I made a stand with the help of GI sheet. Also I added male headers to the other end for convenience. The push button circuit will be installed right next to my bed, while the other end will be connected to micro controller board. I used 6 push buttons with 1K pull down resistors, and soldered 4 meter long ribbon cable to it. The remote: I used a perforated board to make the remote. ![]() So to prevent that, keep the receiver in dark, otherwise you will get garbage in the serial monitor.Īfter prototyping, it's time for some planning to permanently setup the whole thing. ![]() Note: The receiver is very sensitive and almost all light sources emit infrared rays that can get caught by the receiver which will interfere it's functioning. Upload the code to Arduino and note down the hex codes of different buttons you want to used. This will only give the hex codes of button pressed in serial monitor. For that open IRrecvDemo from IRRemote in the examples. Now you know the protocol you have to use.Īfter this, you have to get the hex codes of different buttons you want to use. In my case it is NEC and "Value" is the hex code of that signal. The letters after "Decoded" is the protocol used. We only care about one thing, the first line. Point your remote to the receiver and press any button, a lot of things will pop up in the window. Now you are ready to determine the protocol of your device. Connect the output of IR receiver to pin 11 after supplying the power to it with Arduino 5V and GND pin. Now go to examples, then IRLib-master and open IRrecvDump, upload the code to your Arduino. Install the two libraries link of which is given in Step 1.
