If I incorporate sketches like this into the paulpaulson sketch will I have problems? #include įastLED.addLeds(leds, NUM_LEDS). When you use a standard push button as an input to a microcontroller pin you can read its state simply by using the digitalRead function. 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? If (stateNew)number=(number+1)%(sizeof(FastLEDfunctions)/sizeof(FastLEDfunctions)) 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 Options marked with can be changed from the LCD controller. 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 define THISISENABLED // this switch is enabled //define THISISDISABLED // this switch. 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. With my current sketch the first button push puts it in Case 1, but subsequent button pushes do nothing. 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.
