Hi, i’m making an automatic plant watering system, as the project has grown the mess of wires got annoying so i decided to tidy things up a bit by making a socket board for the power connections needed for the various devices.
When i plug everything into the socket board (i think it’s too simple to be called a power distribution board!), everything powers up fine but the analogue sensor readings are off, but when i hook it all up with wires and crocodile clips the sensor readings are accurate, so the problem obviously lies in my plug board :
The board is just stripboard with a row of JST XH connecters soldered in place (the soldering is fine, no shorts) so i’m thinking that since they are all on the same copper strip then interference must be occurring.
I’ve read that a 0.1uF cap across each socket output may reduce noise, is it okay to use that value in my project (which runs on 12V and 5V with no individual device using more than 400mA) ?
