Can anyone point me in the right direction?

Blink Without Delay

Code Blocking, Medium level tutorial.

Tutorial on code blocking. Attached is: LEDsequenceDelay.ino LEDsequenceMillis.ino LEDsequenceDelayFlowChart.jpg LEDsequenceMillisFlowChart.jpg Two sketches are presented in this tutorial: In the first sketch, the user wanted to be able to push a switch on pin 2 and have LED6 toggle on/off. However, switch control of LED6 is a hit and miss proposition as other LED control takes up most of the controller’s processing time. This sketch uses the delay() function which stops normal code exe…

Why add a flag to Blink Without Delay (BWD) ?

Newcomers to Arduino, soon discover the usefulness of using the Blink Without Delay (BWD) technique for timing events. As most old timers realize, adding a Flag to this technique can prevent subtle and often unanticipated problems. For those newcomers who do not know what and why a Flag should be used, hopefully this discussion will shed some light on the topic. In the code segment below, we are looking for a time interval to expire. When we want to start event timing with BWD, we make ledOn…

State Machine and Timers, Medium level tutorial.

This sketch introduces the concepts of: macros structure enumeration BWD (Blink Without Delay timing) technique timers State Machine The purpose of this example is to integrate the above concepts into a sketch to see how they can be used to simplify coding and make that coding more efficient. An important feature is you can control your Timers. Under program control, Timers can be running, restarted and disabled. When it comes to the ‘State Machine’, you can see how the sketch’s current st…
