Infrared Receiver
Infrared Receiver
On the Image you can see 2 IR Receivers. Both work, the only difference is the board on the left also includes a led light that lids up when an infrared signal is being received. Very useful for your first projects as it will help you indicate that everything is correctly connected.
In the following picture you can see a setup that allows us to load the program to receive and send IR signals without changing components. Pin 2 is being used for receiving the IR signal. Pin 3 is being used to send IR signals.
Below I will leave you the programs to receive the Signals and another on how to Send the programs. At the end I will explain how to change a raw signal so it can be used in the sending program. So with the receiver receive a signal and then apply some changes and then use it in the sender program as you want.

Convert Raw code for Sending
Convert Raw code for Sending
In the following steps I will explain how to convert a code received like this in a format for the sender program. So for example the following code is being received:
FFFF817E
Decoded NEC: FFFF817E (32 bits)
Raw (68): -20800, 9050, -4450, 600, -550, 600, -500, 650, -1650, 600, -1650, 600, -550, 600, -500, 650, -1650, 600, -550, 600, -1650, 600, -1650, 600, -550, 600, -500, 650, -1650, 600, -1650, 600, -550, 600, -1650, 600, -1650, 650, -500, 600, -550, 600, -550, 600, -500, 600, -550, 600, -550, 600, -1650, 600, -550, 600, -1650, 600, -1650, 600, -1700, 600, -1650, 600, -1650, 600, -1700, 600, -500, 600,
Then to use this code remove the first number. In this example -20800
9050, -4450, 600, -550, 600, -500, 650, -1650, 600, -1650, 600, -550, 600, -500, 650, -1650, 600, -550, 600, -1650, 600, -1650, 600, -550, 600, -500, 650, -1650, 600, -1650, 600, -550, 600, -1650, 600, -1650, 650, -500, 600, -550, 600, -550, 600, -500, 600, -550, 600, -550, 600, -1650, 600, -550, 600, -1650, 600, -1650, 600, -1700, 600, -1650, 600, -1650, 600, -1700, 600, -500, 600,
Then replace the negative numbers with a positive number (so -4450 will convert in 4450)
9050, 4450, 600, 550, 600, 500, 650, 1650, 600, 1650, 600, 550, 600, 500, 650, 1650, 600, 550, 600, 1650, 600, 1650, 600, 550, 600, 500, 650, 1650, 600, 1650, 600, 550, 600, 1650, 600, 1650, 650, 500, 600, 550, 600, 550, 600, 500, 600, 550, 600, 550, 600, 1650, 600, 550, 600, 1650, 600, 1650, 600, 1700, 600, 1650, 600, 1650, 600, 1700, 600, 500, 600,
Then put the field indicator in front of it and add also the brackets at the end and ; Also do not forget to indicate how many values you have because each remote control can have different amount of values
unsigned int RobotCornerProgram[67] = {9050, 4450, 600, 550, 600, 500, 650, 1650, 600, 1650, 600, 550, 600, 500, 650, 1650, 600, 550, 600, 1650, 600, 1650, 600, 550, 600, 500, 650, 1650, 600, 1650, 600, 550, 600, 1650, 600, 1650, 650, 500, 600, 550, 600, 550, 600, 500, 600, 550, 600, 550, 600, 1650, 600, 550, 600, 1650, 600, 1650, 600, 1700, 600, 1650, 600, 1650, 600, 1700, 600, 500, 600};
Copy this line in the program and you now can use this code in the sender program.
