The dot matrix clock was built without the use of a regular Arduino board but uses the ATmega168 with Arduino bootloader and assembled on a breadboard. An RTC clock compensated by temperature is used ...
When a Minnesota outfit of all-star DIY-ers called 1.21 Jigawatts won this summer's Red Bull Creation Contest, we couldn't wait to have them create a project just for PM readers. Here, a couple of ...
NYC beaches are where tropical beaches addicted to meth go to die. So says [Vije Miller] in his write-up for his Arduino sand matrix printer. It’s a clever idea, five servo-operated cardboard plungers ...
The circuit is driven by a MAX7219 IC that is being controlled through an Arduino microcontroller board, to create an 8X8 LED matrix. The connection of the LED matrix and the IC was done on a ...
In preparation for Makerfaire, [hwhardsoft] needed to throw together some demos. So they dug deep and produced this unique display. The display uses two synchronized peristaltic pumps to push water ...
Most of us have an 8x8 LED matrix from one of our Arduino kits. What can we do with them? This module investigates how to use these interesting devices. Along the way, we describe a fun electronics ...
