I’ve built the 8 step and after fixing a few dumb errors I still have some major problems, hopefully someone with experience can give me a few pointers.
At the moment, I am powering just from the arduino USB, should that be an issue?
When i power up, I am getting the LED for step 8 illuminated, it’s unstable and seems to be more consistent if I am touching a metal part of the pots or panel, which would indicate a grounding issue wouldn’t it? I’ve metered out all the ground points on the jacks and pots and they all connect to gnd above the D2 on the nano.
I can use the forward / back switch, which moves the lit LED across the steps, although it seems to stick at step 5. the LEDs illuminate when the corresponding buttons are pressed, but, for some reason button 8 illuminates LED 7 and vice versa, although the LEDs seem to be connected to the correct pins.
One thing I should add is that the LEDs are built into the buttons and they don’t have polarity, not sure the name of this kind of LED but whichever way you wire it, it lights up so I am guessing any diode functionality is lost, which i imagine may be an issue.
I can post some pics of my build later, but its very over complicated due to my choice of buttons and the fact its on a small panel.
Getting ready to sell my soldering iron and take up knitting…please save me!
