To convert an ordinary toy car into a remote control car, the first step is to control the gear of the vehicle through the remote control, that is, rc supplies，the gear must have a motor and signal reception.
Second, the accelerator pedal should also be controlled by the remote. It can be a motor or an electromagnet. Of course, it also needs to receive a signal. The brake electronic control also needs to receive the signal, as well as the motor and the electromagnet. and feedback, signal light control systems, vehicle dynamic information feedback (such as probes), radar cruise.
Remote control car remote control principle
The remote control is mainly composed of a microprocessor chip that forms a remote control signal, a crystal oscillator, an amplifier transistor, an infrared light-emitting diode and a keyboard matrix. Its working principle is as follows: the oscillator inside the microprocessor chip IC1 forms a high-frequency oscillator through pins 2, 3 and an external oscillating crystal X to generate a high-frequency oscillating signal.
After the signal is sent to the timing signal generator, a 40KHz sinusoidal signal and timing pulse signal are generated. The sine signal is sent to the code modulator as the carrier signal; the timing pulse signal is sent to the sweep frequency signal generator, the keyed input encoder and the command encoder as the time standard signal of these circuits.
