התרחיש
A dual door control system where capacitive touch sensors provide momentary operation for safety. Upon releasing the touch, motors stop and doors spring close.

פענחו את ההחלטות שמאחוריו.
01
Use of low-side N-channel MOSFET switches for simplicity
02
Momentary touch sensors with pull-down resistors ensure motors are off when not touched
03
Freewheeling diodes protect against inductive kickback
Applicable to automatic door systems requiring fail-safe momentary touch control, such as hospital or cleanroom doors.
