I’m a beginner and I’m trying to setup a plant watering system with a LCD printout. I’m able to get the lcd to show “pump on” and “pump off” appropriately, the pump doesn’t actually turn on and off. Any ideas?
Your code could be wrong, your wiring could be wrong, you may not have enough volts or amps to run the pump... and it could be all or some of the above. Or other things I haven't thought of.
Sketch, schematic, links to tech data on parts used, clear well lit in focus pictures showing how things are wired would enable an informed answer. But that's the best you're going to get from that picture, I think.
Your topic does not indicate a problem with IDE 2.x and hence has been moved to a more suitable location on the forum.
Please provide
- A full list of all specifications of the components components that you use; links to those components are acceptable.
- A schematic / wiring diagram with ALL connections (including all power connections); a photo of a hand drawn one is fine.
- Your code; please use code tags as described in https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum/679966#posting-code-and-common-code-problems
You are trying to supply power to the relay (YEL, PUR) and the pump (ORG) from the Uno (BLK, WHT) via the breadboard rails. You must use an external power supply for the relay and the pump.
