Previous Lesson..

In the previous lesson, we went through the basics of the Arduino Programme software and hardware, the functions had certain codes and language, for example, the one i remember that happens once to start;

void setup(){ Serial.begin(9600);}

we used codes to function a Red LED light, might be interesting to check out morse code?

then we moved on to circuits, which i slightly remember being taught in secondary science...enjoyed it because its hands on and i picked up quick so might think about revisitng and sharing some previous notes and knowledge on circuits!
