Another illustration demonstrating how IR Emission works on Raspberry Pi, for introduction how IR Emission works please refer to this link. IR (Infrared Receiver) is a device / component which receives IR signals and can independently receive IR rays and output signals also compatible with TTL level compatible for all kinds of infrared remote control or infrared transmission. The goal of this experiment is to receive and send signal when remote infrared transmission are pressed.
Component Required
- Raspberry Pi / Banana Pi / Orange Pi (If your using Banana Pi or Orange Pi See first the GPIO Pins)
- IR Receiver Module / NEC IR 38k IR / VS1838 / AX1838HS
- 1k Resistor (Optional if your using IR Module)
- Solder Less Bread Board
- Jumper Wire / DuPont Wire
