Build L293D Dual Motor Driver Board for Arduino

Hello Instructables enthusiasts...

Nowadays buying the boards for the projects is very expensive.. But it can be construct at very low cost.

I required L293D dual H-Bridge motor driver board for my next instructables .

So, to save bucks for my next project I constructed L293D driver board.

In this Instructables ,there is detail content to construct L293D driver board.

L293D IC -1

16 pin IC socket -1

PCB -1

Terminal Blocks -3

Male Header pins -4

IC7805 -1

Hookup Wire - 0.5m

Diode- 1N4007 -4

Tools:

Soldering Iron

Snipper

Screw Driver

• Place Arduino board or print of Arduino on PCB to mark its Dimensions and screwing holes
• After Marking Dimensions , cut it accordingly
• Now insert 16pin IC socket at center of he PCB
• Insert Male header pins on both side of IC socket by some distance
• Insert Terminal blocks on top,left and right side of the ic socket.
• Insert IC 7805 below the top terminal block(above the IC socket)
• Solder all the Components.

1. Short 1,9,16 pins.
2. Short 4,5,12,13 pins.
3. Connect 2,7 to each header pins of that side respectively.
4. Connect 15,10 to each header pins of that side respectively.
5. Connect 3,6 pins of IC socket to terminal blocks through Diodes,such that voltage flows from IC to the motor only.
6. Connect 3,6 pins of IC socket to terminal blocks through Diodes,such that voltage flows from IC to the motor only.
7. Connect input pin of IC7805 to the +voltage input pin of the terminal block (which was above the ic socket).
8. Connect Ground pin of IC7805 to the (-) ground pin of the terminal block (which was above the ic socket).
9. Connect output pin of IC7805 to the 16th pin of ic Socket.
10. Connect 4th pin of IC socket to ground pin of IC7805.
11. Connect 8th pin of IC socket to the +voltage input pin of the terminal block (which was above the ic socket)

CIRCUIT ATTACHED

Solder all the connections carefully

After soldering the components, insert IC L293D into the socket.

YES! IT'S COMPLETED...:)
