Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Synthesis of nanostructured cubic phase SnO 2 thin film and its trace-level sensing of CO gas This study presents a cubic phase SnO 2 thin film gas sensor with ultra-high CO sensitivity and 1 ppb ...

This project automates street lighting using IoT. The system turns ON street lights when it becomes dark using an LDR sensor and can be enhanced with motion detection for energy saving. LDR senses ...
