An application of using a microphone with an arduino is if you want to build some type of sound alarm circuit, in which sound triggers a circuit event such as flashing sirens or turning on a buzzer. For example, if you have a room that should be very quiet and someone breaks into it,...
The UART or serial module that is attached to the back of the LCD is responsible for sending and receiving serial communications between the Arduino and the LCD and it has a onboard potentiometer to adjust the brightness of the screen. What you need for this project is: An Arduino UNO Seri...
Issue 1: I saw a post about the problem of the FreeRTOS scheduler not started on Core1, or not enabled Core1, which could resolve the Arduino sketch not running (but I don't know how to configure it within ESP32-Arduino libraries/board from inside Arduino IDE. Could it be a efuse ...

How to Connect a Pot Using three Leads Since a Potentiometer normally has three leads, it can be used either in a 2-way deferentially varying resistance mode or in the form of a 1-way single variable resistor. We leaned in our previous explanation how a pot may cause a variable different...
Simple Arduino Sketch for PCF8591 This example outputs the raw ADC values to the serial terminal, for each analogue input. On the breakout board these are connected to the LDR (Light Dependent Resistor), the thermistor and the potentiometer. ...
var potentiometer = (bytes[0] << 8) | bytes[1]; return { potentiometer: potentiometer }; } 2. [OPTIONAL] Once you have the decoder code defined in TTN, you can test the payload which is being sent from the device to verify if the decoded value is the right one. ...
