in some wiki it says: “If your device is not muted, you will hear three beeps that signal a countdowns”, but we fail to find a buzzer on the PCB photos of imp? Is there an audible device on the imp? We just purchased 10 imps for starters, so we are curious about all features that are or are not present.
Ah, that wasn’t clear. The beeps during the Blink-up process come from the phone (or tablet), not the imp. They’re your warning to go and point the screen at your imp.
There’s no beeper, sounder, or indeed any moving part at all in the imp itself.
