these are the photos of pcb, the black-red wires are for connection of battery of 6V, 4.5AH connected through 7805 voltage regulator(to prevent circuit components from any damage). 4 motors are used.

did you use ceramic capacitor of "0.47micro farate" ??. I have used electrolytic but circuit is not working.
plz rply soon..............
Jul 28, 2011. 8:40 AMrobot1398 says:
i dot think u would get a electrolyte capacitor of 0.47uf thats impossible
u can get a ceramic capacitor of 0.47uf

the motor is running as soon as i put da battery..da driver is not listening to the mc..wat to do??
Mar 6, 2011. 8:58 AMtbone121 says:
great job, but you should post some pictures of the actual building process and maybe a video of it operating
Mar 7, 2011. 5:11 PMzazenergy says:
Agreed. This looks really cool, but it would be great to get some more photos.

Nice project :)

How to connect the Not gate between Dtmf decoder(mt8870) and atmega16??[N1 to N4] I have used the 74LS04 NOT gate. cant figure out which connections are to be made. You havent specified how you used the same in the circuit diiagram

Also how did you make the four wheel drive?? using gears or adding two more motors in parallel??

Plz reply soon
