This project is a beginner-friendly Arduino sketch designed to demonstrate how the Serial Monitor works in real-time. It calculates and displays the area of a circle using a simple mathematical ...

The serial-monitor tool is a command line program that interacts via stdio. It accepts commands as plain ASCII strings terminated with LF \n and sends response as JSON. Install a recent go environment ...

Plug the RFID module into the breadboard with enough space around it. Connect the VCC pin to the Arduino's 3.3V (not 5V), and ...

The Serial Monitor on the computer and the Serial Port on the Arduino must have the same data rate (baud rate). Usually, the baud rate is 9600, so the programming statement is Serial.begin(9600). Set ...

You can use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and print it out to the serial monitor or to display it on an LCD ...

6. Connect the Arduino to your computer using the USB cable. Open the Serial Monitor in your IDE to see the values from the sensor – this will also help you to calibrate your plant monitor. The IDE ...

Every new generation of computers repeats the techniques used by the earlier generations. [Kim Salmi] created an ASCII-based quadcopter simulation game using an Arduino that displays on the ...

He wanted to do a little more with the equipment so he ditched the watch and built an Arduino-based heart rate monitor ... which is shown on the 2.8″ LCD screen seen above.
