Parts you need
1.transistor switch circuit.
2. Two ir sensor pair for each channel
3.battery
4.our diy robot chassis

hi welcome to the third part of five part robot series.
this is the same transistor switch circuit that i have used in LIGHT FOLLOWING ROBOT AND LINE FOLLOWING ROBOT i didn't change anything from previous build

we just need to reposition the sensors

this is the circuit diagram.here you can see all connections.just swap motor connections.

time to assemble circuit board on our diy robot chassis

i am using a cardboard piece to hold sensors

Test it if needed adjust variable resistor. And enjoy.
