Iam a novice in robot building..
i came to know abt this site due to 50$ robot
this website is simply awesome

iam currently arranging money to buy servo motors for 50$ robot.
but before building it iam thinking to make smthing more simpler than this.
so i camea across this page while googling.

here is a transistor based line following robot.


but iam not able to make out where the wires are connected in the circuit
iam really pissed off trying to make out how the wires are connected?

can smby plz show the simpler version of circuit.
or just a drawing or anything else?

i hope smbdy might help me a bit

The wire connection are based on the circuit diagram schematics.

Why not able to do it? what is you problem? all the wires are connected based on the circuit.

I've uploaded an image. The red is connected to +4.5v power supply, the black circles are connected to ground and the purple circles are the photoresistors or "LDR's".
