		<br>
		==Description==
		This keyestudio microphone module is fully compatible with micro:bit control board. It is a sound detection device, an analog signal output device.<br>
		It is mainly composed of a MIC head, a LM358D chip and a potentiometer.<br>
		When the microphone detects sound, and converts it into a voltage signal; then amplifies it through the LM358D chip.<br>
		The potentiometer is used to adjust the signal amplification.<br>

		There are total 6 rings on the module. Note that two G rings, two V rings and two S rings are separately connected. G for ground; V for 3V; S for signal pin(0 1 2).<br>
		We can work out the sound volume by reading the analog value of signal end.<br>
		When using, connect the module to micro:bit control board using Crocodile clip line.
		<br>
		<br>
		== Technical Parameters ==
		* Working voltage: DC 3.0-3.3V
		* Output signal: Analog signal
		* Dimensions: 31mm27mm4mm
		* Weight: 2g
		* Environmental attributes: ROHS

		<br>
		== Source Code ==
		[[File:Ks0423-4.png\|600px\|frameless\|thumb]]<br>

		<br>

		== Example Result ==
		Connect well the module, then send the source code to the micro:bit main board.
		<br>
		You should see the LED matrix show the rolling dot. Or you can open the serial monitor of Arduino IDE to see the analog value of current sound volume.
		<br>
		The louder the sound, the greater the analog value is.
		<br>

		<span style=color:red> Pay close attention to: you can turn the potentiometer on the module to adjust the sound magnification, which also will enlarge the analog value.<br>
