: Hi Tom
: I have created a circuit off this one of your to read a voltage to the games port.
: http://www.epanorama.net/documents/joystick/pc_circuits.html#generalinput
: One thing I am not 100%
: The input to games port from the circuit appera to reference ground, not the 5v as the pots would in a joystick.
Yes. This circuits connects to joystick port ground and the joystick input.
It does not connect to joystick port +5V, because this circuit is designed in such way that this circuit generates it's own +5V from where it feed the signal to the joystick port.
The circuit image is attached to this message.
: Does that output from the circuit go to pot input and gnd to PC gnd
Yes.
: Or does the circuit output go to 5v and the gnd go to the games port input ?
No.
: Thank you for your time.
: Cheers
