The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Welcome to a concise yet powerful showcase of two Arduino UNO projects built for intelligent robotics and sensor-driven alert systems. This repository presents: Line Following Robot — a mobile robot ...

What if your Arduino could feel temperature the same way your skin does - and react to it? With a tiny sensor like the LM35, that's exactly what we can do. This small integrated circuit measures the ...

The LM35 is a precision integrated-circuit temperature sensor (PTAT; proportional to absolute temperature) manufactured by Texas Instruments (https://www.ti.com ...

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 ...

We’ve all been there. Your current project has hit a wall, or the next step will take days to complete, and you need something to do in the meantime. So you start a project that you envision will fit ...

What if your Arduino could notice someone getting close without touching anything at all? No buttons, no pressure sensors, no physical contact - just light. That idea might sound a little bit like ...
