The majority of the cost for a big sign comes from the LED strips. The 60 LED/meter strips regularly sell for $5/meter. The display is 7 strips high, so the strip cost comes out to about $11/foot.

Instead, you simply open the Arduino software (which can be installed on your Windows desktop or accessed online), write your code, and upload it to the board. Then, you're basically set.

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 ...

Here is ‘blink’ modified to work TXLED and RXLED as well as LED-BUILTIN. int RXLED = 17; // The RX LED has a defined Arduino pin int TXLED = 30; // The TX LED has a defined Arduino pin // the setup ...
