Hi guys, I built a Hbridge motor driver using the IC L298N. But it is not working properly. It is swithcing properly with the inputs but it is not drawing the current required for the motor. I am sensing the out Voltage as 8v but when i connect the (...) (25 years ago, 21-Dec-99, to lugnet.robotics.handyboard)

Need more information. What kind of "light" sensors are you referring to? CdS cels, IR light sensors, active sensors? There is alot of information on wiring sensors in the Handyboard manual available in the Documentation section of the MIT (...) (25 years ago, 20-Dec-99, to lugnet.robotics.handyboard)

(...) As always with the "what is better" question, I must ask... What do you mean by "better"? They will operate the same, I think they have the same cable pinout. The Hitec ones are cheaper usually, but a little larger for the same specs. At the (...) (25 years ago, 19-Dec-99, to lugnet.robotics.handyboard)
