Could you please help me with the following points :
[A] I want to provide onboard power supply to my line follower robot. So, which battery should I use?
[B] How to connect the line sensor quad to the Avr development board?
I am connecting it to the PORTD in the following manner :
1) The two wires, out of which one is black, to V-.
2) The two wires, out of which one is yellow, to V+.
3) The remaining two wires to PD6 and PD7.
Please let me know if it is wrong?
P.S : I am asking all this beforehand, because I am afraid if any of the components might get damaged because of wrong use of battery or wrong connections.
Thank you!
