Hello guys,
Do you have RF transmitter and receiver not working after you programmed?
Do not worry, you can use this techniques to check your devices.
Step 1:
You can simply test if both are working or not.
connect both as shown in the image.
when you connect the data pin to 5V is mean on (send signal 1).
and, when you connect it to the ground is mean off (sending 0).
If you see in another side the LED is flashing according to 1 and 0, is mean that your device is working.
Now you can start programming :)
