Summary of LIGHT FOLLOWING ROBOT WITH ATMEL ATTINY25
This article describes a simple light-following robot project built around the Atmel ATtiny25V microcontroller. The robot uses two LDRs to detect light sources and controls motors via an H-bridge circuit powered by a 3.7V Lithium-polymer battery. The design emphasizes simplicity, utilizing basic components like resistors, capacitors, and transistors to create a stable, functional device suitable for electronics hobbyists.
