The robot has to go in a straight line and when it hits/detects a wall in front if it, It has to turn.
I have already have 2 geared motors, 2 wheels and a caster wheel.
So i believe, I need the wheels, motors, caster wheel, couple of op-amps and sensors to keep the wheels at a steady rate to go in a straight line.
I have 1 question....How the hell do i put everything together, what goes first...seconds...third...etc...
Can I pull this off?
I believe we are allowed to use that because he only told us not to use micro controllers and no programming.
Do you want me to order the L293 part?
Yes, you are right about the part of going reverse to avoid hitting the wall.
I cannot find 4093. Can I use a NAND gate( replacing the 4093)?
funny, i got the 4093 easily
but I am having a hard time finding L293 on the web. All i see is L293D,L293N,L293B and more...
