The idea here is to use a cheap clock from IKEA, wire in a bunch of LEDs, connect and Arduino, and then use the 1Sheeld to trigger color changes depending on the traffic time between two points.

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 ...

Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...

Macomb County has launched a pilot project to install heating technology on certain traffic signals because LED lights don't produce enough heat to melt snow and ice to make them fully visible.

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 ...
