Lesson 9 IR Receiver Module
Introduction
An infrared-receiver (as shown below) is a component which receives infrared signals and
can independently receive infrared rays and output signals compatible with TTL level. It is
similar with a normal plastic-packaged transistor in size and is suitable for all kinds of infrared
remote control and infrared transmission.
Components
- 1 * Raspberry Pi
- 1 * Breadboard
- 4 * Jumper wires (Male to Male, 2 red and 2 black)
- 1 * Network cable (or USB wireless network adapter)
- 1 * IR receiver module
- 1 * IR Remote Controller
- 1 * 3-Pin anti-reverse cable
Experimental Principle
In this experiment, send signals to IR receiver by pressing buttons on the IR remote controller.
The counter will add 1 every time it receives signals; in other words, the increased number
indicates IR signals are received. The schematic diagram:
