i'am making a sensor circuit using arduino ic standaloe and i need all the 19 pins
i need pin 0,1 and 2 to be configured as input
in the sketch i set them as input but they are not working proberly
here is my code
#include <TimerOne.h>
#define output_v A0 //vn
#define output_i A1 //in
#define bus_voltage A2 //vb
#define load_current A3 //il
#define load_current_2 A4
#define converter_current A5
#define sel1 0
#define sel2 1
#define sel3 2
#define p0 3
#define p1 4
#define p2 5
#define p3 6
#define p4 7
#define p5 8
#define p6 9
#define p7 10
#define p8 11
#define p9 12

#endif
#ifndef sbi
#define sbi(sfr, bit) (_SFR_BYTE(sfr) |= _BV(bit))
#endif
