H-Bridge +2 DCs motors
Two DCs motors controlled by H-Bridge
|
This project is aprototype to check the correct functioning of a H-bridge (SN754410 ) controlling 2 DCs motors.The control is perfect with two pots and two switches that allow to change the direction (backward ,forward)of the motors.The motors are powered off with a one 12 volts battery. |

Hi this is a very interesting project, i have two question how are you protecting against back emf from the motors? and did you use any optoisolaters ?Guillermo Vigal # Feb. 16, 2011, 10:34 p.m.
The SN754410 has diodes to protect against kicback current. No, I needn`t optoisolatersmojotexas # Oct. 29, 2011, 3:45 p.m.
The fritzing file just looks like a mess. Something wrong with it? Also, reading up here: http://www.sparkfun.com/products/315, there are those who say the internal diodes against kickback are insufficient and that you do need external diodes. Any thoughts?mojotexas # Oct. 29, 2011, 3:53 p.m.
--ignore previous comment about the Fr file looking a mess. I updated my Fritzer and it looks great.grecogianni1 # Aug. 7, 2012, 2:28 p.m.
Grandioso ! ascolta a me basterebbe pilotare un solo motore ma con due interruttori per la marcia avanti-indietro E'possibile ? se si come ? Grazie molte Great! listen to me it's enough to drive an engine, but with only two switches for forward-backward, leaving the engine should be stopped and should be controlled by switches Spreader is? if you like? thanks a lot
