Sure, here's a concise summary: The 8x8x8 LED Cube is a decorative piece controlled by an Arduino Uno, capable of displaying various light patterns. It uses a 93dn8wy (SN74HC595N) IC, PN2222A ...

If the beam is broken, sample() returns true because the logic level at the top of the transistor is about 5 VDC. If the beam is not broken, sample() returns false because the logic level is close to ...

Animate multiple 24 VDC LED garlands with flashing and variable brightness (13 different parameters) with one Arduino Nano multi-tasking with FreeRTOS. After my previous project with one Arduino ...

[Alex] needed a project for his microcomputer circuits class. He wanted something that would challenge him on both the electronics side of things, as well as the programming side. He ended up ...

Sure, the physical build itself looks great, but it’s what [Michael] did with the firmware that impresses us the most. He’s using an Arduino Mega to drive the 7x7x7 cube and manages to squeeze out ...

All residential and industrial units have energy meters that show energy consumed by the users. But the power (watts) is not shown by these meters, except by some new models. During measurement, all ...
