Hello guys, i have been trying to make a IR controlled car. But i have a problem that the IR remote controller's codes are changing by the distance. When the distance like 1 inches it's OK with the code. I mean the controller sends same codes but when i change the distance between IR controller and receiver, the codes are changing significantly. Also, when i stabilize the distance the codes are changing nonstop.
By the way the IR controller is my helicopter's controller. Here is the photo of controller.
How can i fix this issue?
