Das Szenario
Design a delay timer switch circuit for controlling a DC fan, turning it on after a delay upon power-up.
Was diese Zeichnung zeigt
Die dahinterstehenden Entscheidungen verstehen.
01
Using RC timing with transistor switch for simplicity
02
Choosing component values to achieve desired time delay
When a low-cost time-delay activation of a DC load is needed without microcontrollers.
