Innovator's Hangout

With help from a friend i could improve the displays stability.. Now the RPM of the motor is pretty good.. Added a mechanical gravity switch so that the display turns on after it reaches a particular RPM. Added an IR switch too..

Finally i built up confidence to use a controller. This is my first project using a micro controller.. I had problems with the stability. So the RPM of the display was pretty less

As the below two posts.. This is again a simple thing using two op amps and motor drivers.. Do note that its the same circuit doing three different things..

This is a basic Obstacle Avoider made by just using two op amps and motor drivers.

I was not much experienced when i took this video.. Mind the lighting :p

This is a basic line follower made by just using two op amps and motor drivers. It traces the edge of the line which makes it look like its turning around when it reaches the edge of the line..
