Hello Everyone,
I am working on a project of a programmable robot (coding robot for kids).
and to save some digital pins I use one analog pin (A0 in my case) for 7 pushbuttons each button has a value or range of analog reading as I set in the code to show if the button is pressed or not. ( i tested it and it works well).
I tried to make an array with a size of 10 to record the sequence of 4 buttons from the set (up, right, down, left buttons) then playback it when one of the buttons is pressed (go button in my case).
I need to return an array with 10 values like below:
For example: if the user pressed (up, up, right, up, left, up) so I need the array to be
SeqArr[]={'f', 'f','r','f','l','f','s','s','s','s'}
f: for forward
r: for turn right
l: for turn left
s: for stop
then I playback with the above sequence.
Please advise if I am in the right way or need to change my direction or learn new things to achieve my goal from this project.
Here is my circuit:
my circuit is like this but adding two buttons and 2 1k ohm resistors.
Here is my code:
#include "pitches.h"
int melody[] = {NOTE_C4, NOTE_G3, NOTE_G3, NOTE_A3, NOTE_G3, NOTE_G3, NOTE_B3, NOTE_C4};
// note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = {4, 8, 8, 4, 4, 4, 4, 4};
#define BtnsPad A0
int BtnValue;
char SeqArr[10] = "";
int upcount = 0;
int rightcount = 0;
int downcount = 0;
int leftcount = 0;
int gocount = 0;
void setup() {
pinMode(BtnsPad, INPUT);
