If I incorporate sketches like this into the paulpaulson sketch will I have problems? #include įastLED.addLeds(leds, NUM_LEDS). The sketch works properly as a standalone. Stefan元8 - here is a typical FastLED sketch. Can anything be done to simply require a push and release? Will some sort of software debounce remedy this? The default is arduino if the micro-controller communicates over a serial port. ![]() ![]() If (stateNew)number=(number+1)%(sizeof(FastLEDfunctions)/sizeof(FastLEDfunctions)) If unsure (or if it changes) see the Wheres my serial port. Int stateNew= digitalRead(ButtonPin)?LOW:HIGH Try this simple sketch using function pointers to the FastLED functions desired. digitalWrite(LED_BUILTIN, LOW) // turn the LED off by making the voltage LOW Or this #define button 7 //Push button on D3 Int state = 0 // integer to hold current stateīutton.attach( BUTTON_PIN, INPUT_PULLUP) #define BUTTON_PIN 7 // Push button on D3 PinMode(button, INPUT_PULLUP) //button as inputĭigitalWrite(LED_BUILTIN, HIGH) // turn the LED on (HIGH is the voltage level)ĭigitalWrite(LED_BUILTIN, LOW) // turn the LED off by making the voltage LOW Int buttonPoll = 0 //integer to hold button state Int state = 0 //integer to hold current state What is my sketch missing? Or is there a better approach? #define button 7 //Push button on D3 I want a subsequent button push to put it into Case 2, a subsequent button push to put it into Case 3, a subsequent button push to put it into Case 1, etc. Click Upload button on Arduino IDE to upload code to Arduino. Copy the above code and open with Arduino IDE. With my current sketch the first button push puts it in Case 1, but subsequent button pushes do nothing. Open Arduino IDE, select the right board and port. I am following this video: Arduino Basics Handling Multiple States - YouTube.Īs a trial I am using three different Blink sequences with the builtin led. Ultimately I want to use a button to switch between different FastLED functions.
