How to make solenoid retract when friction applied. Answered
I have a 12V solenoid that was going to be used in a project with a spring loaded door. It was wired into an arduino project and all was going well. That was until I realised that if the bolt had any friction on it that it would not get retracted when power was applied.
I wonder therefore whether there is a simple way of making the bolt retract even when friction is being applied?
Alternatively, is there a simple mechanism that could be made where friction can be applied to something else that doesn't add friction to the solenoid bolt itself so that when the bolt is retracted the secondary part is free to move and release the sping loaded door.
Any help would be appreciated.
