I have worked on Arduino, and know it pretty well now, ive also worked with wireless interface with arduino. Could help you with the project, let me know more about you and the project.

I just tried to build a robot. Got the ideas,circuits from the net. Dunno where it went wrong. My robot didnt even start. My guess is that the 100rpm motor needs more power. I verified the arduino code and its right. Dunno whether i have a prob with my encoder and decoder. Bought a new one and tried again. Its a failure! 😦

i think You can use LM293 & ULN2003 or the darlington transistor logic over there

I used LM293. But its not working. I m not using any modules here. Just circuits.

Instead using the IC and make it complex, you’ll get a motor driver circuit which also does contain the same lm293 ic only, but using that will make the analyzation easy… and regarding the problem u r facing with motors, use a 12v battery that should possibly give more battery life… but ensure that your motora doesnt get overloaded…
