Hey there I am connecting a IR photo gate kit to a delay timer made on a breadboard.
The output of the IR photo gate is a PCB 3-way Terminal block with markings NO/OM/NC (left to right) and I am not quite sure of where to connect these wires to my delay timer kit.
Can someone give me any tips becuase whenever I search on google for PCB terminal blocks its only sales on them and nothing to do with how to use them or connect them.
