Voice detection module ,receives an ambient sound through the pickup and convert it to an electrical signal, which amplified by the LM386 chip and outputs the signal. Figure potentiometer can adjust the magnification.
Note: GND pin of the module is connected to GND of arduino or pcduino, VCC is connected to 5V of aruino/pcduino, NC is not connected , no need to connect, SIG pin is connected to analog input ports of arduino/pcduino, is A0-A5 pin.[/vc_column_text][/vc_tab][vc_tab title=”Touch module” tab_id=”1393403736-2-89″][vc_column_text]
Touch module, through the human body electrostatic detection ,as the function of the buttons. is as the ordinary buttons.
Note: GND pin of the module is connected to GND of arduino or pcduino, VCC is connected to 5V of aruino/pcduino, NC is not connected , no need to connect, SIG pin is connected to analog input ports of arduino/pcduino, is 0~13 pin.[/vc_column_text][/vc_tab][vc_tab title=”Light intensity sensor module” tab_id=”1393404021838-2-1″][vc_column_text]
Light intensity sensor module ,by photoresistance perceiving light intensity,then amplifying circuit will make the signal magnifying. The output voltage correlates strongly positively with light intensity ，So the voltage value can characterize the light intensity .
Note: GND pin of the module is connected to GND of arduino or pcduino, VCC is connected to 5V of aruino/pcduino, NC is not connected , no need to connect, SIG pin is connected to analog input ports of arduino/pcduino, is A0-A5 pin.[/vc_column_text][/vc_tab][vc_tab title=”Potentionmeter module” tab_id=”1393404069336-3-1″][vc_column_text]
Potentiometer module,can be seen as a slide rheostat, by rotating knob to change the size of the resistance.Three pins on the potentiometer, pin 1 and pin 3 resistance is the fixed value R, is the biggest adjustment range of the rheostat. Rotating potentiometer knob, the resistor of pin 1 and pin2 R1 changed, pin2-pin3 resistor also change.But always follow R1 + R2 = R.
Note: GND pin of the module is connected to GND of arduino or pcduino, VCC is connected to 5V of aruino/pcduino, NC is not connected , no need to connect, SIG pin is connected to analog input ports of arduino/pcduino, is A0-A5 pin.[/vc_column_text][/vc_tab][vc_tab title=”Key module” tab_id=”1393404103019-4-4″][vc_column_text]
The key module, can be seen as normally open switch, when pressing the switch , the switch is closed, the hands is off, the switch automatically disconnected .
Note: GND pin of the module is connected to GND of arduino or pcduino, VCC is connected to 5V of aruino/pcduino, NC is not connected , no need to connect, SIG pin is connected to analog input ports of arduino/pcduino, is 0~13 pin.[/vc_column_text][/vc_tab][vc_tab title=”Buzzer module” tab_id=”1393404140721-5-10″][vc_column_text]
The buzzer module. Passive buzzer, electricity will produce the fixed frequency sound,can be used to make a prompt or alarm sound.
Note: GND pin of the module is connected to GND of arduino or pcduino, VCC is connected to 5V of aruino/pcduino, NC is not connected , no need to connect, SIG pin is connected to analog input ports of arduino/pcduino, is 0~13 pin.
