Cars are not only played by small children - nowadays, when every person has at their disposal shops of radio-controlled models and their assortment, playing cars has become a hobby and hobby of many adults. Radio-controlled cars are quite expensive, and the question arises - what to do for those who want to have a simple radio-controlled model, or at least a model with an attached remote control, but do not have enough funds to buy it? You can try to make an elementary machine on the control panel with your own hands.
To assemble the model, take a simple small electric motor with an axle on which you will then slide the wheels; button from a computer mouse in duplicate; long enough wire and body for the car, which can be whatever you want it to be.
Take two small wires and solder them to the button with a soldering iron. Solder the opposite end of one of the wires to the electric motor, and the other to the positive pole. The third contact will already be on the motor - the negative pole.
To make a reverse in the typewriter, and not be limited only to the front, repeat the same steps with the wires on the second button from the mouse.
On the battery prepared in advance, connect the plus and minus. Take two batteries - one for each button. Make a remote - the basis for batteries and buttons.
When everything is ready, make a case for the car, put the wheels on the axles of the electric motor and check if the assembled structure works. When you press one button, the machine should go forward, and when you press the other, it should go back.
Based on this simple scheme, you can make a more complex car on the control panel - use your imagination and invent new interesting solutions.
