I was searching for a project to do. I searched the list of projects given on this site and i found two interesting projects: 1) Park-Aid http://www.electronics-lab.com/projects/automotive/005/index.html 2) Temperature-Contolled Fan http://www.electronics-lab.com/projects/motor_light/025/index.html I have given the links, so u can see them. I thought i could use more info on these circuits, so can anyone help me. i know this much info is enough but i am still a noob in electronics and so i could use some more extra info.
