Nabend allerseits
Ich bin am Bauen einer Fernsteuerung für eine Gartenbeleuchtung und eine Kamera. Per Handsender (TX) kann der Videolink ein- und ausgeschaltet werden. Ebenso die Beleuchtung (Relais 3), hier aber mit einer toggle-Funktion.
Zusätzlich möchte ich ein Feedback von der Box im Garten, die mir sagt, ob der Videolink/Lichter ein, oder aus ist. Dafür sendet das Funkmodul 1x pro Minute den Zustand. Später soll noch die Leerlaufspannung der Akkus übermittelt werden (setze ich später um)
Die Relais-Funktionen funktionieren soweit einwandfrei. Nicht aber das Feedback. Irgendwas scheint faul zu sein. Das Display zeigt aktuell immer “OFF” für Videolink und Lights.
Code für die Box im Garten:
#include <SoftwareSerial.h>
int Relais1 = 12;
int Relais2 = 13;
int Relais3 = 8;
int LightsState = 11;
int VideoLinkState = 9;
const byte numChars = 32;
char messageReceived[numChars];
char keyWord1[] = "ActivateTimer1";
char keyWord2[] = "StopTimer1";
char keyWord3[] = "ToggleRelais3";
char command1[] = "VideoLinkON";
char command2[] = "VideoLinkOFF";
char command3[] = "LightsON";
char command4[] = "LightsOFF";
unsigned long last = millis(); //set timer
const unsigned long INTERVAL = 1000L*60*1; // Intervall 1 Min.
unsigned long lastRun = 0 - INTERVAL; //
int StateOfLights;
int StateOfVideoLink;
SoftwareSerial HC12(2, 3);
void setup() {
HC12.begin(9600);

while (HC12.available() > 0) {
charReceived = HC12.read();
if (charReceived != endMarker) {

if (ndx >= numChars) {
ndx = numChars - 1;
}
}

}
else if(strcmp(messageReceived, keyWord2) == 0) {
digitalWrite(Relais2, HIGH);
delay(100);

}
else if(millis() - last > 250){
if(Relais3state == 0 && (strcmp(messageReceived, keyWord3) == 0)){
digitalWrite(Relais3, HIGH);
}
else if(Relais3state == 1 && (strcmp(messageReceived, keyWord3) == 0)){

}
}

}
}
if (millis() - lastRun >= INTERVAL) {
StateOfLights = digitalRead(LightsState);
StateOfVideoLink = digitalRead(VideoLinkState);
if(StateOfLights == HIGH) {
HC12.print(command1);
}
