Remote Car DIY Part.2 – the Car

Last time I made the part of controller.

This time I are going to build the car circuit.

 (There are some problems about the circuit . Transistors are already included in L293D,so there is no need to add transistors between driver and motor.)

Then soldering the parts…

Finish

 We got the main part of the car after inserted IC

Next step we need set the motor

I use SG90 and turn the servo power by DC directly

I add two 2.2k ohm resistances to the sensor board inside the servo

and shave the latch on gears.

 In the end I put everything together
