Achei esse cara pesquisando por ai ele cria VideoAulas toda semana sobre arduino e como criar coisas passo a passo muito simples e fácil.
Já esta na semana 11 mas eu colocarei aqui pouco à pouco por falta de tempo.
Para quem não entende inglês estarei explicando abaixo basicamente o que ele fez, mesmo sendo extremamente intuitivo o video não precisando necessariamente de tradução mas...
Episódio 1
Esse Episódio em específico trata sobre:
--> Arduino
--> LED
--> C/C++
--> Efeitos Pisca-Pisca (Blink no arduino.cc)
Após o video todos os código que precisara e circuitos:
/* Jeremy's First Program It's awesome! */
int ledPin = 13;
void setup() { //initialize pins as outputs pinMode(ledPin, OUTPUT); }
