In this tutorial i will show you how you can make webpage control distance measurement using nodemcu microcontroller. you can see the all reading on your smart phone using wifi connection
Let's Start,
Required Hardware
Required Software
Arduino Sofrware Link
Connecting the Hardware
* Nodemcu pins need wired are below:
* pin D0 on Nodemcu ---> on ultrasonic -- trig Pin
* pin D1 on Nodemcu ---> on ultrasonic-- echoPin
* Vcc on Nodemcu ---> on ultrasonic pin Vcc / +5v
* Gnd on Nodemcu ---> on ultrasonic pin Gnd
Circuit Diagram
Setting Up Arduino IDE
First we download the library , Now open arduino ide software then click on sketch ==> include library ==> manage library ==> and search for ESP8266Wifi and download the library. and also download WiFiClient and ESP8266WebSerber library.
Next, select the board , go to Tools ==> Board ==> Search for Nodemcu 1.0(ESP-12E Module) ==> and select this board.
If you don't have ESP8266 board installed then follow the steps, Go to Tools ==> Board ==> Board manager ==> and search esp8266 by ESP8266 community, and download the board.
Code
Download the skecth below the link , and open code , and we need to do some changes, just type your wifi ssid and wifi password.
To know more about other project visit us on official website IoTFever.tech
if you need my help in any other or custom project then visit us on offical website
Now , upload the source code.
Final Step
After the successful upload of code then turn on your Hotspot , and wait for connecting nodemcu , open serial monitor you see message Conneting , then after conneting it will show one IP address , and you will see the distance measurement reading of your ultrasonic sensor, to see this reading on mobile screen ,just type this IP address in your mobile browser , you will see reading measure by ultrasonic sensor.
and here you are finish with project , Enjoy your project.
