Serial.print(F("File : ")), Serial.println(_FILE_) the bool array contains the following information: Struct RGBPATTERN, // red=off, green=off, blue = off, and so on. we build a data structure containing the different pattern for the RGBLed the byte array RGBled contains the address of the red pin of the RGBLed, and so on. you may need to change these constants to your hardware #define ProjectName "How to pause and continue a loop with a button press?" This approach minimize the line of codes and makes the modifications of the RPBPattern more easy, if you like.Ĭheck the sketch and study how the commented sketch works.ĭon´t hesitate to contact me in case of questions. Class defintions aren´t used, but I have made a RGBPattern object by using the struct and array instruction. I have made a sketch with respect object oriented programing. How To Install Library On Arduino IDE, Go to Tools Manage Libraries Search ezButton, then find the button library by ArduinoGetStarted Click Install button to install ezButton library. PinMode (BUTTON, INPUT_PULLUP) //(**Not required**) How about, which pauses the LED processing #undef MyHWĬonst int BLED=12 //Blue LED Anode on Pin 9Ĭonst int BUTTON=A1 //The button is connected on pin 2Ĭonst int BLED=9 //Blue LED Anode on Pin 9 Is there a need for the if statement if you just return the button state Return current //Return the current button value PinMode (BUTTON, INPUT) //(**Not required**)īoolean current= digitalRead(BUTTON) //Read the button stateĬurrent = digitalRead(BUTTON) //Read the button state again PinMode (RLED, OUTPUT) //Set Red LED as output PinMode (GLED, OUTPUT) //Set Green LED as output PinMode (BLED, OUTPUT) //Set Blue LED as output Int ledMode = 0 //Cycle between LED states const int BLED=9 //Blue LED Anode on Pin 9Ĭonst int GLED=10 //Green LED Anode on Pin 10Ĭonst int RLED=11 //Red LED Anode on Pin 11Ĭonst int BUTTON=2 //The button is connected on pin 2īoolean lastButton = LOW //Last Button Stateīoolean currentButton = LOW //Current Button State However, what happened was it only worked when I held it, not when I pressed it. If ( lastButton = LOW & currentButton = LOW)īut, I want the mode to switch to ledMode=0 once I pressed the button. (I want to make it switch between each mode every second, for example: Here is my current code ( I am a beginner).
