![]() ![]() KEYPAD: The Keypad for our remote is made up of four individual buttons which is wired to the data pins of the data pins AD0 to AD3 of the encoder IC. The above Remote control Circuit consists of three important components Keypad, Encoder IC HT12E and a RF Transmitter RF433 module. Also transmitter sends the movement signals through wireless medium and receiver fetches the signals for the destination. Starting from Keypad which controls the movement of the Car whereas Encoder and decoders are meant to encode and decode the movement signals for secured transmission. ![]() The above blocks are divided into two sections Remote and Car for the purpose of understanding. To build a RC car we need to make sure that these blocks are available. This article is focused to guide hobbyists to build their own homemade RC car with minimal components. But most of them didn’t know where to start and how to build it, some even got deceived by its complex looks. Remote control Cars also known as RC cars are something every electronic hobbyists would love to build. ![]()
