I am doing a project involving reading the emotional state of a user.
I have a pulse circuit that outputs a high and low to determine each beat of the heart connected to the digital input of the board. This functions perfectly.
Where my problems start is trying to read an analog voltage. This is a circuit measuring the resistance of the skin. Using a multimeter I can see a clear value coming onto the input/gnd of the k8055. When i try to read this value using the board nothing occurs. Even without anything connected to the analog inputs I get a value of 143 for A1 and 138 for A2. This doesn’t change when I connect my resistance circuit. I have no idea what is happening here, especially since the board is working with digital inputs.
Thanks in advance,
Morten
It seems that the card is in test mode.
Remove jumpers SK2 and SK3.
See more detailed instructions on page 13 of the manual.

I owe you a drink and then some. Thank you very much, i might not fail my university project now 
Thanks, not a bad idea… indeed.
BTW: You have an interesting project ongoing.
With a further development you’ll get it working as a lie detector.
Again found one practical application for the K8055 card!
I wish success to your project!
Yes the project is quite interesting. I am actually building a series of 2-player mini games in java that will interact with the signals. For example one game is a straight line race where the aim is to stay calm to make the veichle increase speed. Java executes a C program polling the board and returns a pulse rate and the resistance (GSR) of both players to be used as a comparison.
If you do not mind could I print this thread to place in my report for the project to show how the problem was solved?
Yes, surely you can do that.
