IR-Decoder
- simple Arduino sketch for decoding IR signals from remote control
- use the IRremote.h library
- output per serial monitor
Hardware Overview
I use a standard ir-receiver like this:
- Pinning is:
- 1...OUT
- 2...GND
- 3...VCC(3V3)
Refer the datasheet of your sensor for pin description!
Wiring of sensor is pretty basic:
The resistor between Out and VCC is optional.
In my setup, i use a third party remote control like this:
Decoding
At first i've checked the raw signals. They looked like expected:
In the end, i get following decoded IR- Signals:
