ES:Control de motor DC con un PWM con un Timer 555. El objetivo fue replicar la frecuencia de PWM que genera una salida analoga de un atarjeta Arduino de 500Hz. Por esta razon se seleciono el capacitor de 0.3 micro faradios y el pot de 10Kohms. Ttotal=0.693*C*(Ra+Rb) como Ra+Rb es la resistencia total del pot1=0.00207seg aprox 481Hz, y con el diodo entre la parte central del pot y el capacitaro, para que al cargar pase solo por Ra oparte del pot conectada a 12V, y al descargar pase por Rb seccion del pot entre descarga y capacitor. Las resistencias de 100Ohms son de proteccion. Mosfet recomendao IRL 510 o IRF 530 canal N Lo dificil es encotrar los parametros para el Mosfet. EN: DC motor control with a PWM with a 555 Timer.

The 100Ohms resistors are for protection. The difficult thing is finding the parameters for the Mosfet.
