I am making a project in which numbers from 1 to 9 are displayed on the 7 segment display I have used esp32 as microcontroller I am using Arduino IDE to program THE CODE IS GETTING SUCCESSFULLY UPLOADED BUT NOTHING IS BEING DISPLAYED ON THE DISPLAY I can't understand what's the problem I have a…

There is a difference (presented below) between "putting current limiting resistor for every segment" and "putting only one resistor for all segments:. "Putting current limiting resistor for every segment (Fig-1)" will not change the brightness of the segments of the display whatever digit is shown…

The segments will soon burn out as there is no current limiting resistor.

Hi @akshansh25 , Welcome to the forum.. The pin assignments confuses me.. Sending in an empty CommonPins causes the esp to reboot over and over.. Simmed it here.. Used different pins.. #include "SevSeg.h" SevSeg sevseg; void setup() { byte sevenSegments = 1; byte CommonPins[] = {4}; byt…
