  What I am presenting in the following set of videos and tutorials is a means to an end. Over the last many months I have answered many times the same questions and seen similar mistakes in programming   I am not necessarily implying what I am going to present will be perfect, it wont. But it will be tested and re-usable and can be taken and applied to your project if you want.   At a minimal I hope it will allow you to learn rapidly some techniques and practices that will all ...

The code uses the "delay" function which waits the desired number of milliseconds before continuing with the next line of the code.   int led = 13; void setup() {                  // initialize the digital pin as an output. & ...
