The Arduino serial begin statement is piece of initialisation code that communicates with the built in serial module within your Arduino. You use it to set up a speed of operation that you want the serial hardware to use.There are other parameters that are hidden from you that setup the ...
Battery Monitor To ensure the battery is functionally optimally, the board supports a battery voltage monitor feature. The feature is enabled via the interconnection that exists between the board’s analog converter and the battery. Smallest Arduino Board Selection Board Arduino has a wide range of ...
serial port. The way you do that is through writing sketches that are converted to code. If you've ever taken a programming class for something like C++, Java, or a web-based language like PHP then you might appreciate how simple they've made it to program an Arduino board. Most of ...
How this TDS sensor works is that it is an electronic pen that is able to measure the conductivity of the water as the electrical conductivity of water is directly related to the concentration of dissolved ionized solids in the water. Ions from the dissolved solids in water create the ...
Open Serial Monitor by clicking “Tools–>Serial Monitor” Step 8 Wait for the string “Welcome to Dragino” and input the following commands input “AT” input “AT+CSQ” input “AT+CIMI” Now you can explore more with this NB-IoT shield and build your own NB-IoT based senso...
Time to download the code to your Arduino! Select your micro controller by selecting "Board>Arduino UNO". Then select your COM port by selecting “Serial Port” and selecting the COM port number you saw earlier. In our example COM36 is in use. ...
We will write a code that will print status of pushbuttons on the serial monitor. To write code, you can use the example of the Arduino IDE under File – Examples – Digital – Button. Alternatively, you can use the code below. It is connected via a pull-down resistor to give us ...

Then I used "make monitor" to monitor the serial port output. By toggling the GPIO0 button I am able to see ESP32 is entering download mode with the indication: "waiting for download". (Even to this stage takes me several days, but its a another story ) The question is now what is...
Here is an example Arduino sketch for a basic motion detector: const byte pirPin = 3; // PIR connected to pin 3 void setup(){ pinMode(pirPin, INPUT); // Set pin as input Serial.begin(9600); // Start serial monitor } void loop(){ byte state = digitalRead(pirPin); // Read ...
