However, i am not catching how i could use the GSR,or even how the the output voltage i am receiving works. Heres a shematic i tried to do and its giving me 1.88volts at the output without me putting my 2 fingers. When i do, i see some random number like .80volts to 1.70 or somewhat... Could you help me out abit? am really late on this project.Anonymoushttps://www.blogger.com/profile/06077974934684143126noreply@blogger.comtag:blogger.com,1999:blog-5960140355437923847.post-5185305858202954222010-01-23T01:51:25.086+07:002010-01-23T01:51:25.086+07:00Thanks Sajid.

It's a good practice to use 780X ICs to isolate your circuit from external interference but use large capacitors on either side, cause u don't want to burn your micro-controller. And it's better to use batteries instead of power supply for biomed projects.<br /><br />Just go through the web and select the ics that match with your reqs. and price.Iftekharhttps://www.blogger.com/profile/09132902877600179430noreply@blogger.comtag:blogger.com,1999:blog-5960140355437923847.post-41333710479622360132010-01-23T00:01:49.929+07:002010-01-23T00:01:49.929+07:00This is a very good guide for me.

Mind if you upload a bigger picture of ur shematic for the skin part? Also i was wndering if you could give me advise on what chip to use for the body temperature. <br /><br />I was also wondering if i should use a power pack of 9volts and use the 7808 to bring down the voltage to 5 volts for the microcontroler.. I hope you could give me some advise because this will determine if i passe this semester! :DAnonymoushttps://www.blogger.com/profile/06077974934684143126noreply@blogger.comtag:blogger.com,1999:blog-5960140355437923847.post-58309033746546891252010-01-21T03:16:56.977+07:002010-01-21T03:16:56.977+07:00gr8 blog iftekhar! descriptive and helpful...gr8 blog iftekhar! descriptive and helpful...Dr. Sajid M Choudhuryhttps://www.blogger.com/profile/06801104383207209828noreply@blogger.com
