From your very first blinking LED to dazzling multi-color sequences, Arduino makes it easy to bring light to life. With just a board, a few LEDs, and some code, you can experiment with patterns, ...

LED candles are neat, but they’re very suboptimal for wish-making: you can’t blow them out. Unless you take the circuit from ...

Many microcontrollers can spit out simple analog video signals if that’s something you desire. However, it normally requires ...

Power management can make or break your Arduino project, especially when running on batteries. From selecting efficient voltage regulation to using deep sleep modes, small changes can deliver huge ...

Electronic devices are built from many different parts. Understanding how these components work together is key to understanding electronics. Circuit diagrams use symbols to represent each component, ...

An Arduino library for 7-segment display modules based on the TM1637 chip, such as Seeed Studio's Grove 4 digit display. The TM1637 chip also has keyboard input capability, but it's not implemented in ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...

Abstract: A boost LED driver features high PWM dimming ratio and optimized efficiency is presented. This LED driver, which having low dropout voltage and is able to drive 3~7 LEDs in series with ...
