![]() ![]() Look at the code used as it is non blocking (of course there is room for improvement) but as a starter for your further experiments. If (digitalRead(btn) = LOW & !buttonPress ) // Stays the same as yours there is nothing that stops you form nesting logic in your switch statement. ![]() but from what I can tell from the documentation theres no restriction on the statements that can appear within a switch.case statement. const int btn = 2 Ĭonst unsigned long buttonPressLong = 2000 // 2 secondsĬonst unsigned long buttonPressDebounce = 50 // debouncing for too short presse Thanks Edgar Bonet Id like to add a function that if the result is less the 15cm the car stop, back and turn left or. The program below does what you want (tested on my uno test lab).Īs Edgar Bonet commented before you should also debounce the button (look it up in WiKi) to exclude unwanted effects The times I use are practical on my hardware, so you could play around by looking at the serial monitor. debouncing for too short presse Thanks Edgar Bonet const unsigned long buttonPressLong = 2000 // 2 secondsĬonst unsigned long buttonPressShort = 250 // 0.25 secondis feasableĬonst unsigned long buttonPressDebounce = 50 Also use variables which are "speaking" making it easier to read code for others. There is nothing like an "automatic" short press recognition. The basics of the switch() statement is that you watch a variable, and. The advantage of using switch case is that it has better readability. To differentiate between different press lengths you need to define them. Hi everyone, Im working on my first switch.case statement after learning that you cant call two functions that run multiple outputs simultaneously, at different rates. 1.Before we dive into the coding, we need to understand what we are working with. We have learnt from these two examples how we can use if else statement and speech cases in programming arduino, we can conclude that the if else statement can be replaced with switch cases. I would do it as a simple state without the blocking whileĭefine two bools bool buttonPress = false const int btn = 2 ĪttachInterrupt(digitalPinToInterrupt(btn),decoder,CHANGE) ![]() For example if temp equals two, case 2 will be executed and Temperature is medium will. If the value stored in the variable matches the case number, the code inside the body of the case statement will be executed. The switch statement selects one of many code blocks to be executed: Syntax. Also I don't understand how to get out of the Switch Case loop. The switch statement looks at the variable inside the parentheses ( temp) and compares it to each one of the case statements. Instead of writing many if.else statements, you can use the switch statement. In my current sketch I have to press 'PushButton1' for 2 seconds in Programming Mode for 2 seconds to change the case. Each case gets selected one after one on the even of 'PushButton1' gets pressed for short time.Īlso if I press 'PushButton1' again for 2 seconds in Programming mode the Arduino should come out of the programming mode. in between if I press 'PushButton1' for 2 seconds the Arduino must enter into programming mode. There are 3 sensors (Temp., Accelerometer & Humidity) will read the respective parameters continuously. I am developing a project for my college. ![]()
