Hello,
I need some help on a project.
I have cannibalized an old CD drive and I want to use it for a gadget fun project where I need it to constantly open and close as long as its switched on.
I have removed all unneeded parts only left the opening/closing motor and the mechanics. Other than that its a 12v motor and that its very small I have no other infos on the motor.
Unfortunately I dont know much about electronics and cannot come up with a simple circuit that will do the trick.
From what I was able to find out myself is that I need something like a H-bridge.
I have searched other threads for a similar problem but unfortunately the attachments do not show. Also there were used much more refined versions using PWM to control the speed and timers to control delays between movements. Do I really need this? I can see that its probably not a good idea to switch polarity while the motor is turning full speed in one direction.
I have been able to wire a dpdt switch so that i can manually open and close it and confirm the motor is working but I want it to do this automatically.
I guess there is a simple solution to my problem but I am really a beginner and cant wrap my head around it.
If someone could draw me a schematic with all the needed pars connected It would be greatly appreciated.
Thanks a lot.
