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 ...

I was digging around in the LM311 (and LM111, LM211) comparator data sheet, and came across this unusual voltage reference (diag right). It consists of an npn cascsode pair of transistors, the top one ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

Arduino RFID technology works by using electromagnetic waves in the radio frequency spectrum for wireless communication and data transfer between RFID tags and readers. From supermarket anti-theft ...

An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

The 2N2222 and BC549 transistors are two old components that are still universally used in the vast majority of electrical circuits today. Their applications include amplifiers, filters, impedance ...
