Description
It’s interesting to hack one of your appliances or lighting projects into a whistle controlled intelligent one. The whistled allows you to do so by simply whistling two musical notes. To set it up, you just need to connect your 5.5/2.1mm DC connector on one end and your load on the other.
To grab a sense of how it actually works, check out the presentation video below:
Specifications
ESD protected PCB, covered in transparent heat shrinkable tubing
Voltage must be between 4.5 and 18V at the input (barrel connector)
Reversed polarity protection
Max current of 5A
16 bits PWM output
SWD pads for programming
Listening range of 15m / 50feet
Cortex M4 microcontroller performing 80 FFTs / sec
Maximum voltage on the screw terminals is 25 Volts (don't forget the flyback diode!)

有趣的是破解你的家電或照明工程的一成哨子控制的智能之一。該吹罰讓您只需呼嘯兩個音樂音符這樣做。要設置它，你只需要你的5.5 /2.1毫米DC連接器連接，另一端的另一負載。
要搶它如何工作的感覺，看看下面的演示視頻：
