RC car Using WI-FI

Today we are talking about an interesting topic for car lovers. For today we will build a RC car that is controlled with Wi-Fi. And we will also make a web application for controlling the moves of RC car.

Hardware required:
Odinub board
Odinub GPIO converter
Two DC motors
L293D Motor Driver
Jumper wires
Power Bank
Chassis of car

Circuit Diagram:
Here is circuit diagram for Odinub board and L293 Motor Driver’s input part.

ODINUB L293 Motor Driver Input
GPIO3_20 (pin-23) B1
GPIO3_2 (pin-21)   B2
GPIO3_1 (pin-19)    A1
GPIO1_17 (pin-17) A2
GND     GND
5V  Vcc

Here is circuit diagram for two DC motors and L293 Motor Driver’s output part.
