Rc Car Transmitter And Receiver Circuit Diagram

The receiver section consists of rf receiver ht12d decoder ic and four leds.

Rc car transmitter and receiver circuit diagram. The rc car decodes the signal and moves accordingly. First we will go over the basic idea of the rc car and the working logic that is involved in the car. There are two blocks the transmitter remote control and the receiver robot car. The circuit is divided into transmitter and receiver sections.

The rc car is a great project for all ages and it doesn t require any programming. When these buttons are pressed it passes the movement signals to the encoder. To operate the toy car you need to hold the transmitter in your hand keeping it pointed at the toy car which has the receiver fitted inside and simply press a switch provided on the transmitter. The transmitter section consists of an rf transmitter ht12e encoder ic and four push buttons.

Model radio control electronics is a non commercial hobby site for electronic enthusiasts with an interest in radio control model aircraft and model boats. The receiver circuit needs to be powered with a 12v supply and transmitter circuit with a 9v battery. Battery is the better option for powering the transmitter receiver circuit. First we will start with the power supply circuits.

The above remote control circuit consists of three important components keypad encoder ic ht12e and a rf transmitter rf433 module. Below pictures showing the rf transmitter circuit with breadboard setup. The remote controller sends out a encoded radio frequency rf signal to the rc car. This guide will provide some general information on how to use an rc transmitter with the basic esc.

Both ics must be mounted on holders. Reader contribution of electronic circuits and model design are also included. The basic esc uses standard rc style pwm signals so almost any off the shelf radio control transmitter and receiver can be used as a simple control system. As you can see the rf transmitter circuit consists of the encoder ic and rf.

The complete circuit diagram including the transmitter and receiver part for this project is shown in the images below. Both the rf transmitter and receiver circuits need separate power supplies. Use 9v dc for powering the transmitter receiver circuits. And below ones showing the rf receiver circuit with breadboard setup.

Here is a flowchart to help you understand the working logic of the robot car. An extra led is connected to vt valid transmission pin of the decoder ic. Working logic for the rc robot car. Using this diagram wire up the supply circuit.

You can see the circuit for the receiver power supply on the right. 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. Interfacing relay to the rx 2b output. Technical data for micron radio control systems is included.
