Hey guys. So this isn't strictly arduino-related, but I really need your help.
I'w taken a mechanical alarm clock from the store and hooked up an arduino nano(and some other necesarry stuff) to it. My goal is to control the movement of the handles.
I soldered some cables to the coil of the clock and hooked up some transistors so i can change the polarity of the electromagnet, the clock is thicking as it should, just not in the right direction.
I think that ----- to you help you ------ you must first help yourself a little, by describing what it was that you actually did. You mention you hooked up some transistors for changing the polarity of the electromagnet.
"hooked up some resistors for changing the polarity" doesn't actually provide much information. You probably need to mention voltages, currents, power, waveform details being applied to the terminals of the electromagnet, timing details, connection details etc.
Maybe also mention whether or not the clock movement is always going in that 'reverse' direction - regardless of what polarity that was applied to the electromagnet.
Normally - before driving something, it's necessary to know procedure (waveform, power, polarity, timing etc) is needed - before driving that something.
Although - for some circumstances ----- if absolutely no information is available (due to it being historically lost), then I guess trial and error or reverse engineering needs to be done.
I think what you're actually trying to do is great. So my comment isn't about the goal. Only about details.
