Last time, we used a light sensor to measure the ambient brightness with an Arduino. When the light hitting the light sensor ...

Last time, we learned about the anode and cathode of an LED, how to distinguish their orientation, and the role of a resistor in limiting current.This time, we will combine an Arduino, a breadboard, ...

Coding games have a credibility problem. Some are genuinely useful learning tools. Others place programming words over an ...

One of the best aspects of ESP32 boards (and by extension, sensors) is their dirt-cheap pricing, and that’s pretty much why I ...

AI ESP32 coding can generate useful Arduino examples quickly, but Jim Solderitsch shows how to keep the learner in control.

Build your own ESP32 and ESP8266 projects this weekend. We detail 10 practical IoT builds, including a Wi-Fi weather station using a DHT22.

AI-assisted coding can generate, explain and debug code. Learn how AI coding assistants work, which tools to consider and how ...

Students received hands-on training in Arduino, microcontrollers, sensors, displays, motors and basic electronics ...

The flip-flop, aka latch, can also be understood as Bistable Multivibrator as two stable states. Generally, these latch ...

Prototypes are easier than ever to build. Shipping them safely is where most developers are falling short. At DevSparks Hyderabad 2026, AI and engineering content creator Arsh Goyal returned for his ...

The **SG90 Micro Servo Motor** is one of the most popular servo motors used in Arduino, robotics, automation, IoT, and educational electronics projects. Unlike an ordinary DC motor that rotates ...

The 2026 edition of the National Electrical Code (NEC) is the result of more than 4,000 Public Inputs (formerly called “proposals”) and just under 2,000 Public Comments. Hundreds of changes were made, ...
