Pulsweitenmodulation
Dependencies: mbed
PwmOut
Pulsweitenmodulation (kurz PWM), ist eine Modulationsart, bei der die elektrische Spannung zwischen Ground (0 Volt) und 3.3 Volt wechselt.
Die relative Länge des Pulses wird Tastgrad (englisch duty cycle) genannt.
Der Abstand zwischen dem Startpunkt zwei aufeinnanderfolgender Pulse wird "Periode" genannt.
PwmOut kann nur mit Pins verwendet werden, welche mit PWM bezeichnet sind.
Das nachfolgende Programm erhöht die Helligkeit der LED an Pin D13.
Anwendungen
- Licht dimmen
- Motoren Geschwindigkeit regeln
