Hello all, I have come here before and got some good advice but now am looking at a different way. I am building a label feeding device which has labels of different sizes. Originally I designed and built with pneumatic but am rethinking things. Here is what I need: a simple DC motor that will feed a label. The labes are basically opaque but the backing is translucent. Is there a circuit which would allow a foot pedal to actuate the motor, which would feed the label out and when it got to the next label stop, then feed again when the pedal is pressed. I am thinking a simple photo cell might work, but the label would have to feed all the way through then when the next label comes between the photocell it would stop until the foot pedal is pressed again. I will try to do up an image but think it is fairly explanatory this way. push the pedal, label feeds out and stops when the leading edge of the next label hits the sensor. I studied electronics long ago and barely used it so I am very rusty.
Thanks all for any help it is much appreciated.
