Hello all.
First of all my electronic knowledge is very very limited and this is not my field. So please excuse my lack of knowledge in this area. Also I accidently posted this in a wrong section, so sorry for a duplicate post.
I am working on a hobby project which I want to use a solenoid to open and close a latch.
To accomplish this, I'm planning to use 2 hall sensors.
A shaft which rotates clockwise holds a magnet in place and passed the first hall sensor at 6 degree which will send a signal to cut the power to solenoid (close state which the solenoid spring close the latch) and when the magnet passes the second hall sensor which is placed at 170 degree provide power to solenoid to open the latch.
Doing a search I came across PICAXE 8 pin Motor Driver Board

Do you think this will server the purpose of what I'm planning to do?
Also I want to add some logic as when to open the latch ( maybe every other revolution). Does this board have such a capability?
My logic is something like this
hall sensor1 is installed at 6 degree on a disk
hall sensor2 is installed at 170 degree on the same disk
the shaft starts to rotate (RPM between 400 – 3000)
magent passes sensor1
cut the power to solenoid regardless of which state the solenoid is
Magnet passes sensor2
if (counter = 1)
provide power to solenoid to open the latch
counter = 0
else
counter =1
Also I like to know if someone can guide me as how such a circuit should look.
Thanks so much
