Hello everyone,
what I am working on is having buttons connected to a 4021 shift in register which i got to work fine then based on this input i want to turn LEDs on or off which are connected to a shift register 595. I must mention that I have 2 595 daisy chained. So my problem is that i don't know how to convert bool led1On etc to a byte. I need your help please.
This is my sketch :
#define Nextion Serial
/* define that Serial will be written as Nextion (when we write Nextion.print the compiler read Serial.print)
*By defining the Nextion as Serial we can change at once the serial port for the whole code,
* with changing the Serial to Serial1 for example
*/
// Defining the SPI library and RF24
// We must make sure to download RF24 library and place it in the arduino libraries folder
#include <SPI.h>
#include <RF24.h>
//#include <nRF24L01.h>
//1st byte is for throttle value from pot
//2nd byte is for brake value from pot
//3rd byte is for Steering Left state
//4th byte is for
//5th byte is for
//6th byte is for
//7th byte is for
//8th byte is for
//Steering potentiometers
const byte Throttle = A4;
//const byte Braking = A5;
//Define arduino pins connected to CD4021
int dataPin_4021 = 8; // Pin 0 of DigiSpark connected to Pin 3 of CD4021
int clockPin_4021 = 6; // Pin 1 of DigiSpark connected to Pin 10 of CD4021
int latchPin_4021 = 7; // Pin 2 of DigiSpark connected to Pin 9 of CD4021
// Define arduino pins for the 74HC595 shift register
int dataPin_595 = 4;
int clockPin_595 = 2;
int latchPin_595 = 3;
// Define variable that will hold the data from CD4021
byte RegisterValue = 0; // Used to hold data from CD4021
// Define the pins for push buttons for debouncing
