I feed with 5v provided by a PC PSU, but I can test with batery.
Ground connection is OK, my multimeter show 0 ohm everywhere on ground circuit
When no buttons are pressed the ball don’t move, floats and falls automatically after 30s.
I wonder if it comes from pot. I bought this one : http://www.newark.com/bi-technologies-tt-electronics/p160knp-0qc20b10k/potentiometer-linear-10kohm-200mw/dp/34R4721?Ntt=1760793
I plug wires like this :
– brown (ADC) in center
– green (GND) at left
– orange (VCC) at right with 10k resistor
On button :
– blue (PC) with 10k resistor
– green GND
V+ is independent on each paddle or can I use one V+ for both ?
