The market may be full of these hi-end remote controlled toy cars, but for a hobbyists making one at home can be entirely a different experience. The article below explains how to configure a simple remote controlled toy car using a ready made 4-relay remote control module.
If you refer one of the previous articles you will find some data regarding buying of ready made, ready to use remote control modules or devices, which just requires to be wired as per the data and you are able to control any electrical device within a range of 100 meters with a press of a button over the remote handset.
Here we are using one of these ready made remote control modules for implementing the remote car operations.
In this article only the circuit and the wiring part has been discussed, making the car body and fitting of the motors and the wheels will be entirely left on the user, the user may take the help of a carpenter or some fabricator for designing the vehicle body.
The remote control module which is being discussed here uses four discrete relays, which can be toggleed discreretly through the 4 individual switches over the remote handset.
The model car is provided with four wheels, two at the front and two at the rear as usual vehicles have.
The remote control unit may be procured ready-made, the one discussed here will be just perfect for the present application.
Moving back to the proposed project of a simple car remote control, we will need the following components for making the main control units of the system:
A couple of DC motors.
8 nos. 1N4007 diodes.
4 nos. relays, 12V, SPDT
12V Battery, 4 AH SMF, or as per the motor rating.
A general purpose PC boared.
2 nos. 12V DC motors, wattage as per requirement
Once the above things are procured, the motors may be suitably fabricated over a selected piece of metal or wooden base, such that two motrs constitute the two front wheels. Two additional dummy wheel may be fabricated for supporting the front motor wheels.
After this, the PCB may be populated and wired up with the relays and the diodes with the help of the given figure, this concludes the relay box assembly.
Next, the four relay outputs from the remote control in-built relays should be connected to the diodes of the above relay box circuit.
The antenna from the remote should be sufficiently terminated using a foot long flexible wire so that the module becomes responsive even from longer distances.
The operation will need battery power, so needless to say a suitable battery will also be required to be placed and integrated with the discussed circuits inside the toy car.
Done!. Now you may test the unit by pressing the remote handset buttons.
As per the integration of the relay serial numbers to the diodes of the relay box, pressing of the buttons A,B,C, and D over the remote handset would produce results in some specific orders, such as: forward, reverse, right and left movements with the car.
The entire PCB along with the remote control module may be suitably enclosed over the base of the model car such that the system gives an appearance of a well groomed homemade remote controlled car.
