Here, the three LEDs are directly connected to Arduino pins with independent current limiting resistors (R1, R2 and R3) which is enough for a basic model. But if you wish to control Hi-Power LEDs (or ...

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 ...

Start with the end of the string so the Arduino ends up at the bottom of the sweater. This will give you easy access to the battery pack and the on-off switch once the project is finished. 9.

Sure, the physical build itself looks great, but it’s what [Michael] did with the firmware that impresses us the most. He’s using an Arduino Mega to drive the 7x7x7 cube and manages to … ...

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 ...

As described on the Hackster Profar blog, as features go, the Shield sports a reset switch, power LED, Arduino pin 13 LED, Pi GPIO pin 13 LED, headers for full Arduino pin access, and ICSP header for ...

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 ...
