Hello everyone, i am building a "propeller led clock" i have done all the work but i am not getting which interrupter to use. i want an interrupter with 3-legs which should give me a level HIGH (5v) output all time But the output should drop to zero (LOW level) voltage when it is put near to the south pole of the magnet. can anyone name a hall-effect sensor that matches my requirement?
And please, with this, name an opto-coupler TOO, which should do the same work.like it should give me a 5v output all the time but the output should drop to 0v when anything comes between its IR.
please tell the name of both (hall-effect sensor and OPTO-COUPLER).
Thanks a lot.
