This 4 -digit 7-segment display section is wired around four common-cathode 7-segment LED displays, and four BC547 npn transistors. The 1K resistors are used for base current limiting, and the 390R ...

One more suggestion: if we use an Arduino PWM pin as the common anode pin, we can power on/off the display and change its brightness. What if using Common Cathode Display. If we put in the sockets ...

The board has four LED arrays resulting in a display of 8×32 LEDs. The MAX7219 takes a 16-bit data word over a 10 MHz serial bus, so programming is pretty easy.

🚀 How to Upload to Arduino 1. Assemble the circuit following the wiring guide above. 2. Open Arduino IDE and make sure the LiquidCrystal library is installed. 3. Copy and paste the code into a new ...

The lights are under the command of an Arduino Nano, which is also tasked with reading button inputs from the board’s side panel. The Nano is interfaced with a Raspberry Pi, which is the true ...
