Dear all,
I'm trying to get my head around inductors. In some instances (like low pass filters) I think I'm starting to grasp their operation. In the schematic below, however, I have no idea. It is part of a line-following robot schematics and the X4s go back to a MCU's ADC inputs to measure what is on the line and what isn't.
Can anyone, please, help me out and explain the purpose of L2 and L3? Also, I have trouble figuring out where the X3-9 would go, but I expect this to become clearer when I understand the L2 and L3.
Thank you for your time,
Edmunds
