Hello, I’m back. In this project I’ll show you how to visualize BMP180 sensor readings in a web server. To start, we will create a domain website on 000webhost.com. The tutorial can be found on my latest project:
After creating the site, go to Tools > Database Manager > Create Database.
Remember the credentials since it will be used in the later part.
Go to Manage Database > PhpMyAdmin > id_ex_esp_data > SQL. Insert this SQL query below and click Go.
CREATE TABLE Sensor ( id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, value1 VARCHAR(10), value2 VARCHAR(10), value3 VARCHAR(10), reading_time TIMESTAMP DEFAULT…
Hello! In this project I’ll show you how to build ESP32 client to insert sensor reading data into a MySQL database using PHP script.
On this project, we’ll need:
This is the high level overview of this project by randomnerdtutorials.
I need to buy a domain and hosting server. The tutorial recommends using BlueHost or Digital Ocean. But, I found a free hosting 000webhost. First, sign up…
Hi, I’m back. On this project I’ll create a web server which display readings from BMP180 sensor. The BMP180 sensor measures temperature, humidity, and pressure. Let’s start!
There are 4 pins on the sensor which will be connected to the ESP32. Follow the pins below:
BMP180 — ESP32
Actually the BMP180 sensor with LCD can be seen on my previous project.
Following the previous project, I’ve already installed the BMP180 library. …
Hello! I’m back :) On this project I’ll show you how to develop a controlling system with Wi-Fi communication to turn on and turn off the LED with a web server.
To do this project, I need:
First follow this schematic from randomnerdtutorials.
This is the raw code…
Hello! On this project I’ll show how Bluetooth Classic and Bluetooth Low Energy work on ESP32. Bluetooth is used for wireless communication in personal area networks (PAN). Bluetooth is a wireless technology that uses low-energy radio waves to send wireless data between Bluetooth-enabled devices. Bluetooth version 4.0 is known as Bluetooth Low Energy or BLE, which remains in sleep mode constantly except for when a connection is initiated.
On this project I will show you how to communicate with Bluetooth Classic by typing message and to switch on the LED via application.
Hello, I’m back!. On this project, I’ll show you how to display temperature, pressure, and altitude on 1602 LCD. This project is a combination of my last 2 projects. Kindly read them before jumping to this project :)
Since my BMP280 was not working properly, I bought a new sensor: BMP180. Let’s see if this works.
I followed the tutorial from randomnerdtutorials. But I didn’t find the combination of BMP180 and LCD. …
Hi! I’m back. On this project, I’ll show you how to display Hello World on I2C LCD. Let’s start!
Or: (LCD — ESP32)
I followed this schema from randomnerdtutorials.com like this:
Hello, it’s me, Chintya. In this post, I will tell about how I spent my time outside college: competitions.
I’ve participated in some science competitions (smth like math, etc.) at high school before so I kinda know what it feels like. Of course, I lost most of the time. But, I keep doing that because it’s fun! I enjoy it more than school :)
My first competition at college was a business plan competition. It was my first year and I didn’t know anything about business. I just participated because I was invited to a team. As expected, my team…
Hello! I’m back with my 3rd project: internal ESP32 sensor. On this project, I’ll show how internal sensor: touch sensor and half-effect sensor work. Actually there is one more sensor: temperature sensor, but I’m not sure if it will really work on my ESP32. Let’s see!
We will learn how capacitive sensor (touch) works. If the sensor is touched, the number shown on the serial monitor will be less than the threshold. What is threshold number? To know, I did the 1st trial.
We will use:
