Jag har tänkt göra två gammal stereo högtalare till en bluetooth högtalare med addressable led som lyser/blinkar.
Arduino koden
const int ledPin = 13; int ledState = LOW; // Generally, you should use "unsigned long" for variables that hold time // The value will quickly become too large for an int to store unsigned long previousMillis = 0; // will store last time LED was updated // constants won't change: const long interval = 100; // interval at which to blink (milliseconds) int program = 1; void setup() { pinMode(ledPin, OUTPUT); pinMode(2, INPUT); pinMode(4, INPUT); Serial.begin(9600); } void loop() { int buttonState = digitalRead(2); int buttonState2 = digitalRead(4); if(buttonState == HIGH) { program = 1; } if (buttonState2 == HIGH) { program = 2; } if(program == 1) { alwaysOn(); } if(program == 2) { blinking(); } } void alwaysOn() // program 1 { digitalWrite(ledPin, HIGH); } void blinking() // program 2 { unsigned long currentMillis = millis(); if (currentMillis - previousMillis >= interval) { previousMillis = currentMillis; if (ledState == LOW) { ledState = HIGH; } else { ledState = LOW; } } digitalWrite(ledPin, ledState); }

Jag hann inte riktigt färdigt med projektet. Jag har fått bluetooth förstärkaren och led:arna men jag har inte hunnit koppla ihop allting. Koden är så gott som färdig. Nu slutar jag med mitt projekt.
