Hi guys,
I am fairly new to electronics and circuits and could really use some help with a circuit I have been trying to design for my Thesis. What I have is a joystick with an 8 way hat. I need to convert the signals from the hat onto one channel to send through to an external A/D card. My problem is the 8-way hat uses four buttons that when pressed determine what position the hat is in. eg: up, button 1 is pressed, Bottom right, buttons 2 and 3 are pressed at the same time.
**broken link removed**
I am trying to design a circuit similar to the one linked above, however I need each combination to have a distinct voltage drop so it can be interpreted by the computer running the system. I can not manage to get the parrallel loops to produce a distinct voltage drop from the single loops, ie when only one switch is closed. I know I have to alter the resistors but have had no luck finding a combination that works. Any help or advice would be greatly appreciated. Hope this makes sense. LOL.
Cheers
