Since I'm a noob when it comes to robotics, you're gonna have to go easy on me with all the terms. I just got VB to control the parallel port and make some LED's flash in sequence, etc. However, when I tried to make a step motor run (I have 2 types with different voltages), the motor didn't move and it just vibrated! Obviously the voltage on the parallel port (4.5V) isn't enough to power a 12v step motor. Thus, i was wondering on how I would get the parallel port to maximize its voltage. Also, what type of devices can I use to increase the voltage externally without screwing up my pc!
First be careful trying to run circuits / Motor having required more power may damage your port. Secondly if you want to operate/control 12V SM with TTL output (5V) you must use amplifier circuit for that you produce 12V from TTL output.
I must advise you increase you electronics knowledge for making customs robotics output.
Good Luck :wave:
