I’m looking for a Mosfet/transistor that can be enabled with a lower power signal (TTL, 3.3v). This Mosfet/transistor should allow an Arduino to be turned on/off (also 3.3v). Can anybody recommend a Mosfet/transistor I could use?
(fyi: powering the Arduino directly by the 3.3v TTL signal doesn’t work, it’s not enough to power the Arduino. The 3.3v TTL signal is the output of a PIR motion sensor running standalone.)
Thanks in advance,
