Finally got my display working for my skeeball score program but now I have a counting problem. I am using sensor inputs (A2, 3, A4, 5, 6, A3, 9). I have the PinMode for A2, A3, and A4 to INPUT_PULLUP. All of the pins accept the count (low) except for pin A4. I cut the jumper on the back of the board to no avail.
Sometimes it will read once then refuse to accept further counts. The voltage at the pin drops to near zero.
I believe solving this problem will give me a workable system.
Thanks for any help, Dave
Update: "It was bad enough trying to troubleshoot my Redboard Plus hookup problems when I stumbled upon a problem with the boards PTH connectors. It appears that on some pins the TPH separates from the female pin header. there is a “short solder connector” but foil beneath it can be separated from the TPH. Took me a while before I found the real cause of no continuity between my wires and the board. I ended up soldering to the "short connector "
Hope this helps someone, Dave"
Thanks for sharing Dave!
TS,
I solved the PTH problem before I ran into the pin A4 not working. This is where I am still stuck. Any comments appreciated .
