    First of all, I apologize for the lack of a “formal” schematic… I tried to draw one out, but got buried in the nuances of it :)\n
    \n
    Second, I’ve done enough research to have [some idea](https://hstech.ro/HC595/) of what my problem is: namely, I need a [decoupling capacitor](https://www.reddit.com/r/AskElectronics/comments/6ubdyt/need_some_quick_helpclarification_on_power_supply/) in the mix. Problem is, I’m new enough to this that I’m not 100% sure where to put it, nor what capacitance I should use.\n
    \n
    So the setup: -I’m using a Wemos(like) D1 Mini to drive 8 relays via an HC595 shift register -The D1 Mini microcontroller, HC595, and relay module are all powered by the same 5V DC and ground -The microcontroller addresses the shift register via 3.3VDC data pins -The relays power a water valve via a separate 24VDC power supply and transformer - plugged into the same AC outlet\n
    \n
    And the problem: everything works just fine UNTIL I actually add the 24VDC power load. Once that’s done, the results are very erratic… usually turning on the correct valve correctly, but rarely turning it off in the same way. As I mentioned, I intuitively suspect noise in the data caused by the sudden power to the valve… but it doesn’t make too much sense since everything is on different power supplies.\n
    \n
    Any guesses as to where I need to put some capacitor(s)? Thanks!!

    First of all, I apologize for the lack of a “formal” schematic… I tried to draw one out, but got buried in the nuances of it :)\n
    \n
    Second, I’ve done enough research to have [some idea](https://hstech.ro/HC595/) of what my problem is: namely, I need a [decoupling capacitor](https://www.reddit.com/r/AskElectronics/comments/6ubdyt/need_some_quick_helpclarification_on_power_supply/) in the mix. Problem is, I’m new enough to this that I’m not 100% sure where to put it, nor what capacitance I should use.\n
    \n
    So the setup: -I’m using a Wemos(like) D1 Mini to drive 8 relays via an HC595 shift register -The D1 Mini microcontroller, HC595, and relay module are all powered by the same 5V DC and ground -The microcontroller addresses the shift register via 3.3VDC data pins -The relays power a water valve via a separate 24VDC power supply and transformer - plugged into the same AC outlet\n
    \n
    And the problem: everything works just fine UNTIL I actually add the 24VDC power load. Once that’s done, the results are very erratic… usually turning on the correct valve correctly, but rarely turning it off in the same way. As I mentioned, I intuitively suspect noise in the data caused by the sudden power to the valve… but it doesn’t make too much sense since everything is on different power supplies.\n
    \n
    Any guesses as to where I need to put some capacitor(s)? Thanks!!
