This project may be useful to drive a roll shutter motor or a car electric window. It works with two buttons (S1,S2), two limit switches (FC1, FC2) and an anti-crushing safety switch (SIC). Since this was my first project using Continua a leggere Roll shutter driver
Two button control systems are often used on industrial presses to keep the operator’s hands away from the dangerous parts of these machines. Just for hobby purpose I designed a logic gates circuit that activates an output if two buttons Continua a leggere Two button control by logic gates
Two counter circuit. The first one drives Continua a leggere Counter circuits
This circuit turns on and off a relay when two resistors of a certain value are detected.
