If (millis() < blinkState.previousMillis + blinkState.OffTime) return then we should check for time to turn it off or else return. If (blinkState.iloopState= 0) // Here the state started and the led is off, or by built-in functions for example : digitalWrite(LEDnumber,LOW)īlinkState.iloopState = 0 // set the current state to off.īlinkState.keepState(blinkState.iloopState) // keep or save the state. Off() //Set the led to custom function you declare like Off() or else return to run other functions until this time come. exceeds the time to make the led on so we should switch it off If (millis() < blinkState.previousMillis +īlinkState.OnTime) return //check for the state time if the current time we should check for time to off, so we can turn it off or else return. If (blinkState.iloopState= 1) // check if the led is on, (1 in this case) to the state, save it and return identify On/off state ( 1 = On, 0= off)īlinkState.keepState(blinkState.iloopState) // store the iloopState or by built-in functions for example : digitalWrite(LEDnumber,HIGH)īlinkState.iloopState = 1 //we use the iloopsstate like On() //Set the led to custom function you declare like On() Recommended variables, usually the operation has loop ( i or j) or both, if it has, then we can declare variables in the state as well. Mainly, it contains the time to run and duration to run loops and duration of pause to run other piece of codes, as a very important variable: (Is Empty), which is flag to detect if the function 1 st run or not, which allows us to initialize values before running the state. Part 1: Task State Structure Structure State Members Variables Part 4 - (optional) Serial Example, adding listening to Serial Port while running the State-enabled function.Part 3 - Call the function calls the state enabled function into the Arduino main loop.Part 2 - Example Function contains loops using State Structure.This code is based on main structure " state" as mentioned. Using the Codeįor more flexibility, I added the feature of time out and the delay between tasks, meaning you can control when the loop makes iteration even if the task in the turn, using: Previous Millis and current Millis. When the code runs, we start this state for every loop, so we can pause the loop (and keep its state and local variables) and run others, then back to it with its last state and so on. IsEmpty which identifies if this task is running or not.End time is the end time to run task and move to the next.Start Time which is start execution time for the task.Task variables local variables (optional).Using this code, you can as an example: using Arduino Pins, read/write run parallel loops, read from and write to ports like Serial port or run any Arduino commands all together without waiting for any loop to finish.Ĭode based on State Structure, which keeps details about task, loop or function like: When you read and apply this technique, you can run your code in this way in Arduino: so it can handle more than one segment with a delay for each one. This state keeps the state for every running loop or function and keeps moving to the next one with timeout for everyone. I solved this problem is to create a Structure, I named it " State". So I created this trick to force Arduino to do so, and I decided to share it with you. These loops deal with several pins and do actions in Arduino board. while listening to the serial port and make an action based on serial reading data. In my last project, I needed to run several loops at the same time. The issue in this scenario is you cannot go through all running tasks or even control the Arduino anyway like listening to serial port, which will be impossible until the current task finishes. Here Is How Arduino Currently WorksĪrduino finishes one task, loop, function, then moves to the next. But what if you have several items and pins you want to read from and write to, or even make several loops at the same time which is impossible with Arduino because it does not support multitasking. Arduino has many capabilities and controllers, pins which can do tasks, this device can execute one instruction per time, which is great if you will use just one pin or even use one loop which is provided by default in the IDE. you can control anything using it and computer.
