Hi all. Very new to this, and no real engineering/electronics background, but I learn fast and follow direction well...
I am trying to have a FSR release a NC electromagnetic lock after a certain force - say 3 N - has been applied to the sensor. I *have searched the forum to no avail. I need help mainly with the coding (assuming this can even be done) but will not turn down any offered schematics.
The lock would be in the locked position when it is getting current, and would release when 3N is placed on the FSR, thereby stopping current flow to the mag lock, +/- 0.2N or so (the force doesn't have to be precise, but it does need to be more than X Newton and less than Y newtons)
I have an Uno R3 and a 5V relay to control the mag lock.
Thanks in advance for any help, and I hope I've given enough info. If not, let me know what other specs you need.
