NodeMcu and buzzer
Posted: 21 Jan 2019, 17:34
Hi all, i'm newbie, i have a nodemcu D1 mini, and with espeasy i'm trying to realize a simple alarm with buzzer.
I have a passive buzzer, same as this https://www.dx.com/p/passive-low-level- ... EXy283SIuU
My problem is when i active the buzzer with command tone or rtttl, the gpio state remain in status high and the buzzer after 1 min it becomes hot and i must shut down the d1.
I can't understand how to set gpio in state low after the tone or melody, as is possibile with the pulse command, i need a capacitor or resistor or is possible via espeasy?
My current version is Release mega-20190116
Thanks to anyone who can help me.
Bye
