Software

BIOFEEDBACK MONITOR using IC LM 555.

I need a link or site that can provide with the required software for this circuit.

Does anyones knows how to get this software to run it or the written program to display the results.

I've add a picture of it under attachments.

It is a biofeedback monitor circuit using IC LM555 mainly used to measure Galvanic Skin Response.


Thanks.

PC's parallel port and any programming language can be used, pulsing LM555 pin 2 low starts read and pin 3 pulse width corresponds to skin resistance.

sory,the threadstarter was me (duckvader),
i mean if i m uising vb.net or C to program it,how should the code look like?

The LM555 won't reliably run from 3V (even if it did a 3V battery doesn't remain at 3V for very long), use a TS555 for this.

i think i will change to a 5v battery instead
