Lesson 9 Infrared-Receiver
Introduction
An infrared-receiver is a component that receives infrared signals and can independently
receive infrared ray and output signals compatible with TTL level. It's similar with a normal
plastic-packaged transistor in size and it is suitable for all kinds of infrared remote control and
infrared transmission.
Components
- 1 * SunFounder Uno board
- 1 * USB data cable
- 1 * Infrared-Receiver module
- 1 * Remote controller
- Several jumper wires
Experimental Principle
Control a certain key (for example, Power key) via a remote controller by programming.
When you press the key, infrared rays will be emitted from the remote controller and received
by the infrared receiver, and the LED on the SunFounder Uno board will light up.
Experimental Procedures
Step 1: Build the circuit
