First Time Poster Here:
I have an Arduino Pro Mini mounted to a PCB. The PCB with Arduino Pro Mini powers 4 LED’s [][][][] There are also two smaller PCB’s that have 1 LED [] on them. so it is connected like. [] --- [][][][] --- []. The LED’s blink in a specific pattern when each button is pressed. I can get the right side to work but not the left.
I have posted the code below:
const int btn_left = 3;
const int btn_right = 2;
const int LEDs_L = 11;
const int LEDs_R = 10;
const int LEDs_BL = 13;
const int LEDs_BR = 12;
int Flag_R=0;
int Flag_L=0;
int Flag_BR=0;
int Flag_BL=0;
int interval=125;
int intervalB=100;
int Delay=6000;
int ledStateR = HIGH;
int ledStateL = HIGH;
int ledStateBR = HIGH;
int ledStateBL = HIGH;
unsigned long current_millis;
unsigned long prev_millis_R;
unsigned long prev_millis_r;
unsigned long prev_millis_br;
unsigned long prev_millis_L;
unsigned long prev_millis_l;
unsigned long prev_millis_bl;
