Int vresistor = A0 // A variable resistor is attached to the Arduino’s analog pin A0. SoftwareSerial nodemcu(2,3) The Rx pin number 2 and the Tx pin number 3 So let’s define a serial port on Arduino’s pin number 2 with the name Nodemcu and pin number 3. So with the help of this, you can make multiple serial ports. #include means that this is a preprocessor directive and. Our basic application setup is completed. Now click on the terminal to open the settings. Now click anywhere on the screen and search for the Notification and click to add. This is the authentication token, we will simply copy this and paste in our programming. Then click on the create button, an authentication token will be sent on your email id, which will be then used in programming. As I said earlier this variable resistor will be used as the sensor.Ĭlick on the New Project and Set the project name as Arduino Nodemcu, if you want you can set any other name.Ĭlick on the chosen device and select Nodemcu. So as you can see the Nodemcu Rx pin is connected with Arduino’s pin3 and the Nodemcu Tx pin is connected with Arduino’s pin2 and the ground is connected with the ground.Ī variable resistor is connected with the Analog pin A0 of the Arduino, while the remaining two legs of the variable resistor are connected with 3.3v and ground.

Well my friends no worries at all, we can define multiple serial ports using the Software serial library, which I will explain in the programming. So now the question is if we are using the Arduino’s default serial port for debugging purposes then how we will communicate with Nodemcu Module? To power up the Nodemcu ESP8266 wifi module, a wire from the output of the voltage regulator is connected with the Vin pin of the Nodemcu ESP8266 wifi module, and make sure all the grounds are connected together.Īs the Nodemcu will communicate with Arduino through serial communication, so for this we need a serial port, as I always say never use the Arduino’s default serial port for communication with other devices, Use Arduino’s default serial port only for the debugging purposes.

As you can see a 330-ohm resistor is connected in series with a 2.5v LED.

The capacitor connected at the output is compulsory. Two 470uf capacitors are connected at the input and output sides of the LM7805 voltage regulator.

The female power jack J1 is connected with the Input and GND legs of the voltage regulator. J1 is the Female Power Jack and this is where we connect a 12v adaptor or a Solar Panel or a 12v battery. Let’s start with the 5v regulated power supply based on the lm7805 voltage regulator. This circuit schematic is designed in cadsoft eagle 9.1.0 version. I would appreciate your support in this way! I may make a commission if you buy the components through these links. Soldering iron kit: “best” You guys should definitely purchase this: The Amazon Purchase links are given below: Let’s continue without any further delay!!! I’m going to use a variable resistor as the sensor for the best understanding. I will also show the value of the sensor on the serial monitor of Arduino. You can monitor your sensors from anywhere in the world using the Blynk app device terminal widget. The only difference is that the Arduino Serial monitor only operates when the Arduino is attached to the laptop or device, while the Blynk app Terminal Widget program is completely wireless and can be used to control remotely. The Terminal Widget program from Blynk app is just like the Serial Monitor from Arduino. Typically the serial monitor is used for debugging purposes. If you’re using Arduino, you’ll know which serial monitor is being used for.
