The four input pins (2-7-10-15) receives motor drive instructions from the MCU. In short, U2 acts as the interface between the microcontroller (U3) and the dc motors (M1&M2) in which instructions from ...

His latest project is a sophisticated line follower. You’ve probably seen “bang-bang” line followers that just use a photocell to turn the robot one way or the other.

The creation of [Ondřej Staněk], this matchbox-sized line following robot is quite impressive. PocketBot’s 48mm x 32mm circuit board also acts as its frame, supporting the wheels, motors ...

These four cases are the only possible conditions for a basic line follower robot. LFR-IR Sensor Card Circuit diagram Our LFR has two infrared sensor cards (left and right) on the bottom of the ...
