IntesityDownFlag = true //enable intensity down adjustment For more circuit examples, see the Fritzing project page. IntesityUpFlag = true //enable intensity up adjustment Stefan元8, yours is th best explanation Ive personally seen about using switch/case decision making process in conjunction with things that only need to take some set period of time then bail out. ![]() TimerPtr = &TimerIntensity //point to this timer TimerPtr = &TimerDown //point to this timerĭigitalWrite(leftLED, !digitalRead(leftLED)) //Toggle LEDĭigitalWrite(rightLED, !digitalRead(rightLED)) //Toggle LED TimerPtr = &TimerUp //point to this timer are we still within the adjustment timeĮlse if (intesityDownFlag = true) //Decrease ![]() If (TimerDownFlag & millis() - TimerDown >= 250ul) TimerPtr = &dummy //pointer to dummy timer A switch statement allows a variable to be tested against several values for equality. If (TimerUpFlag & millis() - TimerUp >= 250ul) if timing is enabled, is it time to stop Irrecv.resume() //restart for next button press If (code(&results)) //is there IR remote button code Example: how to use switch case statement in Arduino programming: switch statement in Arduino: switch statement in Arduino -In my previous article, we learned about if and else if statements. PinMode(intensityLED, OUTPUT) //this is a PWM output pin Unsigned long * TimerPtr = &dummy //pointer to the current timerĬonst byte upLED = 13 //turns on as long as the UP button is pressedĬonst byte downLED = 12 //turns on as long as the DOWN button is pressedĬonst byte leftLED = 11 //toggles on/offĬonst byte rightLED = 10 //toggles on/offĬonst byte intensityLED = 9 //a LED which can have its intensity adjusted Unsigned long TimerDown //DOWN arrow on the remote Then loop could have another switch / case that looks at that variable and takes the appropriate action. You could have a variable called whatToDo and each case could set it to a different value. Unsigned long TimerUp //UP arrow on the remote Best to refactor this entirely so that the cases just set a variable that lets the loop function know what to do. IRrecv irrecv(RECV_PIN) //create instance of 'IRrecv'ĭecode_results results //create instance of 'decode_results' The repeat code is re-sent as long as an IR remote button is pressed.Ĭonst byte RECV_PIN = 7 //IR receive pin ![]() This remote sends the button code (example 0xFF629D) then a repeat code 0xFFFFFFFF The remote used here uses the NEC protocol. Sketch to demonstrate using an IR hand remote to control Arduino outputs. Now, think about your problem and write a function to start and stop blinking based on the state of your switch Without that break at the end of each case, the sketch would continue through to the code for the next case, resulting in un-requested maneuvers. So, each call to go results in a 200 ms maneuver. Also, get rid of the "magic numbers" in your code. The break in each case exits the switch block and the sketch moves on to the next command, which is delay(200). When your code is in the IDE, press Ctrl-T to reformat to a style most of us can read easily. How can I make a loop to keep my light blinking and stop it when press the button again (or the same button to turn off)? I alredy can turn the light on and off and also make blink, but just when I press the button. I just used the switch/case to read the inputs and make the decisions. Hello, I'm doing a simple project for my university where I turn on/off a lamp with a IR Remote control. ![]()
