I started with arduino few weeks ago, and my bigest problems are the motors.
Now I am working in a project were I'm using a H-bridge to control a DC motor by a IR remote control. The problem apears when I conect de 9V batery to the pin number 8 of my H-bridge to bring more power to my motor and this ones doesn't respond. I am using also another battery to supply the arduino.
Thanks!
Hi!
Did you connect all the other pins on the H-bridge?
If its the H-bridge that comes with Arduinos lab kit http://www.arduino.cc/documents/datasheets/L293D.pdf
To make anything happen you must connect:
(8) Vs to motor battery
(16) Vss to Arduino 5V
(4,5,12,13) one of these to Arduino ground
The following 3 pins to 3 Arduino digital ports
(1) Enable 1
(2) Input 1
(7) Input 1
The following 2 to the motor
(3) Motor
(6) Motor
Then write a program that sets (1) = 255, (2) = 1, (7) = 0
Hi,
9V battery, not a 9V smoke detector battery is it? ? ?
They will not do the job at all.
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
