Vendar ko program zaženem mi začne pri float V=0; javljati napako "expected unqalifield_id befor "float" " in potem pri vseh vrsticah naprej enako.
Mi lahko kdo pomaga kje sem naredil napako?

Kjer imaš "float v = 0;" poskusi dati raje "double v = 0;"

Sem zgornjo napako resil
Sedaj pa mi javlja pri :
void reset_leds(){
for (int x = 0; x < 4; x++){
digitalWrite(ledPins[x], LOW);
javlja napako ledPins was not declared in this scope
Kako resiti to ?
Se zahvlajujem v naprej za nasvet

Hm, nnovartis19, kot lahko vidiš na spodnji sliki, mi prevede gornji sketch iz prvega prispevka, brez napak v Arduinu IDE v.1.6.5.
Tudi za deklaracijo float v=0 ne javi napake.
Torej, ker nimamo steklene krogle ne moremo vedeti, kateri Arduino IDE uporabljaš za prevajanje, kakor tudi ne katerega Arduina misliš uporabiti za tole.
Daj, prosim, malo bolj se potrudi pri objavljanju prispevkov, ne da je vse nametano, kakor pač pride s copy/paste!

popravi na:
digitalWrite(13, HIGH);
void reset_leds(){
for (int x = 0; x < 4; x++){
digitalWrite(x, LOW);
indeksi se ne pišejo v oglatih oklepajih v tem primeru
