Circuit Cellar magazine Dec ’06 had an article “Multitiered Security System” using a PIC18F4580 and an MV1210 fingerprint module from Bioscrypt.com among other circuits. They said easy microcontroller interface but they didn’t say cheap.
i dont want to use modules and i want to start my design from raw materials (i.e. glass, LED, sensor) and use the PIC.
By the way, thank you very much for the reply. Its just that i have to pay for the article (dont have a credit card). If you have a copy of the article can you email it to me please (chi2king@yahoo.com). Thanks
