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 ...

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 ...

A phototransistor is wired to an Arduino Uno and positioned above a 32×32 RGB LED matrix. ... and then the program turns on the LEDs that the sensor saw during the scan.

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

One of the device's biggest updates is an 8x8 LED matrix that can be seen through the Bolt's translucent shell. This matrix displays helpful prompts like a lightning bolt when Bolt is charging on ...

Sphero has a new robotic ball, and it's noticeably livelier and more colorful than its older models. The Sphero Bolt will look like the SPRK+ at first until its 8x8 LED Matrix starts moving and ...

An inexpensive 8×8 IR sensor and an 8X8 LED panel join to form a crude but usable thermal camera. He leverages several ready-made libraries and walks through how and why he chose them and how he ...
