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

MicroPython is a well-known and easy-to-use way to program microcontrollers in Python. If you’re using an Arduino Uno Q, though, you’re stuck without it. [Natasha] saves the day by bringing us a a ...

LED face masks have come a long way since their early days as clinic-only treatments. Nowadays, these futuristic devices are as commonplace in our everyday routines as they are in high-end spas, and ...

This project is a discrete hardware implementation of a 10-LED chaser using a timer-based clock and a decade counter. An astable oscillator built with the NE555 generates a tunable clock signal, which ...

A project for Tiny Tapeout 4. This is a simple circuit implementing an LED chaser animation for a seven-segment display, but a configurable bank of clock dividers allows the animation to run at ...

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, ...
