There are many differences in every radio control car model. The important thing is that when you subtract between them exists a difference of 455 KHz or other IF ANY, here we are using a standard FI, but can be anything we want, while we know what we're doing. Once we wrapped an IF signal now want to recover the information that it brings. To this comes a stage within the stage internal RF detector is called, there if it is important to consider whether the signal was generated in AM or FM, and AM detectors that are very different from FM.

A detector output signal going to find the basis of R / C ready to be demodulated by the next stage (demodulator or decoder r / c). The stages are coupled by transformer, so the impedances are well suited.

Filters

The filter is the last stage in the radio transmitter where the goal is to clean the radio control car       signal of any spurious and thus reduce the potential for interference to other computers in rc. A typical RF filter consists of a network of coils and capacitors.

Features

The minimum system configuration is designed to load and can be used by the program SIEV31. The system makes it possible to operate the car using the arrow keys of a computer. It is capable of storing up to 1 hour and 10 minutes of experience. The trajectory that repeats the car is displayed on the LCD of the system at least at the same time it is sent to the computer for future storage.

The system is capable of receiving from the computer recorded a track in a text file (. TXT) and run it. The radio control car has two motors, one for front and rear and one for left and right.

The rc car is based on switches, each engine has three contacts, one common and two that specify the direction of the motor, this means that to enable a motor to a direction to the common terminal together with the corresponding terminal and to go in the opposite direction have to raise the common with the other terminal.

You can focus on a project with a main aim to exploit the characteristics of the top model. You can control of a radio control car minimal system with a microcontroller 8031 to control a remote control car and memorize a route, commands established by immediate direction or pre-recorded route file.
