In the article My First Robot:
the circuit seems to be contradictory or may be not. in the list 4 IN4148 diodes r listed. now from the circuit, there are only 2, if i make them 4 by making the circuit twice, then other components will also be 2 in no. & the other must be 4 in no. & when i make the other components 4 by making the shown circuit 4 times then the no. of IN4148 diodes become 8 or 5.so what to do?PLZ Help! & also help me understand the relay to motor connection.
