With the help of this Instructable, You will be able to make a Programmable Robot car using Mediatek LinkIt One board and L293D Motor Driver IC.

Here, LinkIt One Board is used as controller to drive the motors in respective directions.

Step 1: Components

1: Robot car chassi(like as shown in the image)

4 :200rpm DC Motors

Mediatek LinkIt One Board

1: L293D IC

Connecting wires

BreadBoard

Step 2: Connections

Assemble the Motors on the Chassi as shown in the picture.NOTE:Connect the motors such that there will be 2 pairs of wires for motor.

L293D has 2 enable pins and VC1 as shown in the L293D IC diagram Connect both of them to 5V on LinkIt One Board.

From the L293D IC diagram:

connect

INPUT 1-D2 on Linkit One board.

INPUT 2-D3 on Linkit One board.

INPUT 3-D7 on Linkit One board.

INPUT 4-D8 on Linkit One board.

OUTPUT 1- Any one wire of Left pair taken from motor.

OUTPUT 2- Remaining wire of Left pair taken from motor.

OUTPUT 3- Any one wire of Right pair taken from motor.

OUTPUT 4- Remaining wire of Right pair taken from motor.

VC2 - +16V from external supply.

4,5,12,13- GND on LinkIt One Board.

Upload the code and Run!! Now your Programmable Robot Car is Functionable!
