Hallo,
ich bin an einem kleinem Projekt und zwar versuch ich 3 verschiedene LEDReihen über 3 Ausgänge über 3 Buttons auf einer Webseite an zu steuern. Mein Problem ist ich bekomm nur 1 Reihe zum leuchten, aber die anderen 2 nicht.
Als Hardware habe ich ein Pretzelboard mit einem ESP8266.
Mein Programm:
#define SSID "MeinWlan"
#define PASSWORD "MeinPW"
#define gLED 5
#define bLED 6
#define rLED 9
#define LED_WLAN 13
#define DEBUG true
const char site[] PROGMEM = {

Ich bekomm immer den Port D9 zum leuchten also die roten LEDs, aber nie die grünen oder blauen...
Bin ziemlich neu was das Programmieren angeht, vielleicht kann mir jemand einen Tip geben was nicht genau stimmt.
Danke!
