I need some assistance. I've wired a simple time delay circuit using the 556 timer based on a 9 VDC power source. The output of the time delay is a relay switch which is intended to relay to a 12 VDC circuit. No big deal - at least that's what I thought.
The timer works fine and activates the relay switch at the end of the intended time frame. My problem comes in when I attach the time delay circuit to the intended device. The intended device is a 12 VDC circuit that uses 16 gauge wire and a conventional AC plug (like a grounded house plug - sorry I don't know the correct term). When I connect the output of the delay circuit to a 16 gauge wire and house plug, the delay circuit continues to reset after the initial delay and firing of the 12 VDC device.
It acts as though when connected to the heavier wire (the delay circuit is constructed on a simple breadboard - I wanted to make sure it worked before soldering it on a permanent board) the heavier wire is picking up some "noise" or other interference and shorting the time delay circuit - starting the timer over and over again. If I remove the heavier wire connection, the time delay circuit seems to work just fine.
Is there some way to transition the input and output (from a bread board or soldered circuit) leads to 16 gauge wire and minimize the risk of the delay circuit from continually resetting? I'm new at this electronic circuits hobby, so I hope that I've explained the problem correctly. Any help would be greatly appreciated.
