Hello guys.
I know that most line following robots use photodiodes or phototransistor or IR recievers.
I wanted to know if using LDR it could work.
The schematic attached is the circuit I'm thinking to use for each receiver.
And maybe instead of connecting directly to the motor I could connect to a comparator first.
What you say about it?
Well the circuit withe the LDR works very simple. The motor speed is proportional to the light over the LDR. So if lets say the line is reflecting light to the LDR one side will go fast and the other motor (assuming its a curve) will be off because of darkness.
