Scrolling Clock - Arduino UNO, RTC, and DHT-11 Hey Science Enthusiasts! Get ready to dive into the world of Arduino with a fantastic project: a 64x8 LED Dot Matrix Clock with temperature and humidity ...

Millisecond‑accurate stopwatch using hardware interrupts Instant visual feedback (time + emoji) on the MAX7219 matrix Single‑button start/stop for lightning‑fast tests Snap‑fit 3D‑printed enclosure—no ...

User input is provided by a digital encoder with push-button. A set of four MAX7219 chips control the entire 256-pixel matrix with just three pins on the Arduino.

Our project is infact an Arduino with Serially Interfaced MAX7219 Operates an 8X8 LED Matrix to display a heart pattern. The MAX7219 IC is a serial input/output common-cathode display driver that ...

An Arduino Nano is then pressed into service to run the show. It’s hooked up to a MAX7219 LED matrix which feeds instructions to the willing participants, who activate the system with a giant ...
