SEQUENTIAL LIGHTS

This project is based on the PIC 16F84A microcontroller which performs many effects using LEDs.

First of all, be careful in feeding the electronic circuit, we must do it only with 5VDC so that it works correctly and we will see the sequences of all the led diodes.

the code was made with the binary code that allows us to use 8 bits for each port

HERE WE WILL SEE THE CODE THAT WAS USED FOR THE PHOTO WE USE THE A AND B PORTS AS DIGITAL OUTPUTS AND GENERATE SEQUENCES FOR THE LIGHTING OF EACH LED WITH A TIME OF 300 MILLI SECONDS SO THAT THIS GAME EFFECT CAN BE PRODUCED UNDER THE MIKROC SOFTWARE CODE

void main() {
TRISB = 0; // sets the address for the output
PORTB = 0;
TRISA = 0; // sets the address for the output
