Paso 3: código

Es un control básico del motor paso a paso de dos botones. En secuencia se enciende uno de los pernos de motor mientras que el resto están apagados. A continuación el siguiente perno motor pasa mientras que el resto son apagado y así sucesivamente. Botón 1 (val 1) es en una dirección (motorpin 1,2,3,4) mientras que el botón 2 (val 2) está en la otra dirección (motorpin 4,3,2,1). El retraso es cuánto tiempo entre cada paso que el Arduino va a esperar. Mientras menor sea el número más rápido. Me enteré de que un retraso de 3 es el más rápido el paso a paso puede ir.
