Hey guys, so in a previous topic of mine (http://www.picaxeforum.co.uk/showthread.php?19095-Limiting-D.C-motor-angle) i was trying to figure out how to use a motor to control a webcam (pan and tilt) and after looking at manual 3 i found using a L293D would allow me to control two motors with ease.
So the aim of this is to use the input from a computer to control the webcam, everything is done however I can not use a 08m chip as i need to serial inputs therefore i am one output pin short therefore the next chip i have is a 18m2 (bit of a leap). when i plug in my serial cable to the breadboard all of the output pins go to approx (varies) 0.75v i dont know why... I have dinner now and when i come back i will make a circuit diagram however i wanted to get the ball rolling....
This is very confusing.
Cheers for the help once again.
