A sophisticated line-following robot using IR sensors and differential drive control.

Arduino Nano (NANO1) – Used as the microcontroller to control MOSFETs. Push Button (with pull-down resistor R4 = 10kΩ) – Provides manual input. MOSFETs (Q1, Q2, Q3 = IRLZ44N) – Act as electronic ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
