TheKY-038is Microphone Sound Sensor for Arduino. The sensor has 3 main components on its circuit board. First, the sensor unit at the front of the module which measures the area physically and sends an analog signal to the second unit, the amplifier. The amplifier amplifies the signal, acco...
We have connected the LED anode pin with GPIO4 through a 220ohm resistor. Later on, in the program code, we will configure this GPIO pin as a output pin. You can use any appropriate output GPIO pins. The cathode pin is grounded with Arduino ground and sound sensor ground. Moreover, we...
Examples of Arduino Sensor There are many types of Arduino sensors available today. Some of them are – HC- SR04 Ultrasonic Module IR Infrared Obstacle Avoidance sensor SoilHygrometerDetection Module Soil Moisture Sensor Microphone sensor Digital Barometric Pressure Sensor ...
Its architecture, fully compatible with Arduino IDE Online and Offline, has a 9 axis Inertial Measurement Unit (IMU), temperature, pressure, humidity, light, color and even gestures sensors and a microphone that are managed through our specialised libraries. Its reduced power consumption, compared ...

Now we can solder the remaining components such as the vibration sensor and the side push buttons. The board I've made didn't had the wings pads for the buttons, that's why I've put some hot hlue behind the buttons. But the final GERBER file has the wing pads for the buttons so ...
