Nettet2. okt. 2024 · Wiring for 7 Segment Display with Arudino, ESP8266 and ESP32. The following fritzing sketches show the connection of the 7 segment LED display to an Arduino ESP8266 or ESP32 microcontroller. The 220 Ohm resistor between the common pin and ground restricts the current to less than 20mA for the Arduino microcontroller. NettetThe MAX7219 breakout board includes a resistor (RSet) for adjusting the brightness at the hardware level. This resistor controls the maximum current supplied to the LEDs and, hence, the overall brightness of the display. The table below shows the resistor values you should use based on the voltage and forward current of your LED matrix.
