TSOP IR RECEIVER

An infrared receiver tuned to react only to IR of frequency 38 kHz. This IR sensor module consists of a PIN diode and a pre amplifier which are embedded into a single package. The output of TSOP is active low and it gives +5V in off state. When IR waves, from a source, with a center frequency of 38 kHz incident on it, its output goes low. It is perfect for making obstacle sensors and to accept signals from most IR remotes.

WORKING

To control a servo motor with remote control, this will give you a general concept on how to control remotely. You should know that the remote control sends Infrared (IR) signals, so we will learn how to receive and read these signals using Arduino.

We use arduino UNO to control the servo motor to make the functionality we want.

We use IR receiver to read IR signals from remote control.

Wiring IR receiver and servo motor is shown in pictures.

Follow the steps of wiring in the picture given above

Copy the library to Local Disk(C 🙂 > Program Files(x86) > Arduino > libraries

Open IR remote demo example from Arduino IDE as picture 1 then upload to arduino board.

Then open serial monitor and try to click on any button of remote control to send a signal to IR receiver, the HEX code of each button must appear in serial monitor as picture 2

Then detect the HEX code of the buttons using to control the servo motor, assume you will use two buttons of your choice, one for clockwise rotation and another for counter clockwise rotation.

For example, use (+) for clockwise and (-) for counterclockwise, so you have to get their HEX codes.

(+) —> A3C8EDDB

(-) —> F076C13B

After uploading the code open serial monitor and Take any remote you want to use or you want the codes off it and press any button.

Now, see in the serial monitor. You will see a code of the corresponding button you pressed. Copy the codes and paste it

In the final code, the functionality is when clicking at any of two buttons the motor is toggling between the rotation in main direction and stop so when first click at any of two buttons the motor will rotate in button’s direction, and when the second click at same button the motor will stop
