Intro: FOLLOW ME ROBOT
Parts you need
1.transistor switch circuit.
2. Two ir sensor pair for each channel
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.
