Hi all,
Can someone tell me the correct way to wire up the Vishay Spectrol 357 pots.
There are three pins on the back of the pot, but I am not sure which goes to v5, gnd, or input on the control board

Cheers

Rhys

Rhys,
1 and 3 go to gnd and 5v, 2 goes to any input. Just make sure pin 2 does not get connected to 5v or you will
smoke your pot. If the pot goes back to front to what you want, just reverse pin 1 and 3 connection.

Rhys,
If u had pin 2 connected to 5volts and the pot was turned closest to the pin connected to gnd then it probably would
complain, and if left long enough would have smoked.
