ACircuit Diagram to Interface LED MAtrix display with Arduino. Now that we have completely understood how a MAX7219 LED Dot Matrix Display Module works, we can connect all the required wires to the ...

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 ...

The LEDs on the 32x8 Dot Matrix Display will react according to the signals that Arduino receives through a microphone that is connected to its analog pin. Arduino has built-in ADC input audio signals ...

This project combines two Arduino Uno boards: one as a master and the other as a slave. The master Arduino handles the LCD display and temperature monitoring using a DHT22 sensor. The slave Arduino ...

18 year old maker and developer Nikodem Bartnik from Poland, has created and awesome Arduino-based dot-matrix printer, capable of creating art on paper 55 cm wide and as long as you need, thanks ...

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.

Kenneth picked up an old dot matrix printer from a swap meet for only $5–what a steal! He then used a BeagleBone –basically Texas Instruments’s version of an Arduino board, to connect it to ...
