Hello, future engineers!! Welcome to my blog! My name is Muhamad Fariz  Ramadhan from STI 2020 ITB. I made this blog to help you guys out about embedded system especially setting up ESP32 to get some conditions. At this time, I am going to show you how connecting ESP32 using Web Server. *DON'T YOU KNOW??* source: smarthuby.com We can connecting ESP32 to our mobile devices such as computer, handphone, and others. The ESP32 will communicate through a web server connected to WiFi. What is WiFi actually? Wi-Fi is the wireless technology used to connect computers, tablets, smartphones and other devices to the internet. Wi-Fi is the radio signal sent from a wireless router to a nearby device, which translates the signal into data you can see and use.   So, now we're going to connect ESP32 to WiFi and communicate through a web server. Let get started! STEP 1 : Required Hardware BMP280 source : elekrtolead. 1. ESP32 Development Board 2. Laptop / PC 3. Micro USB cable 4. BMP280 (soldere

Hello, future engineers!! Welcome to my blog! My name is Muhamad Fariz  Ramadhan from STI 2020 ITB. I made this blog to help you guys out about embedded system especially setting up ESP32 to get some conditions. At this time, I am going to show you how connecting ESP32 using Bluetooth. *DON'T YOU KNOW??* There is two types of Bluetooth. 1. Bluetooth Classic  2. Bluetooth Low Energy (BLE)    So, now we're going to connect ESP32 to Bluetooth and display the texts in serial monitor xor in mobile device. Let get started! STEP 1 : Required Hardware source : bluetooth.com 1. ESP32 2. Breadboard 3. BMP280 4. LED 5. Resistor 330 Ohm 6. Jumper wires male-to-male 7. USB Type-A Cable 8. Android Smartphone with Bluetooth 9. Laptop/PC Desktop STEP 2 : Required Software 1. Download Some Application in your Mobile  a. nRF Connect for Mobile b. Serial Bluetooth Terminal STEP 3 : Circuit time & Demonstration 1. Learn the concept     Here is the schematic circuit. source : randomnerdtutorial

ESP32 with Multiple I2C Devices

Hello, future engineers!! Welcome again to my blog! My name is Muhamad Fariz  Ramadhan from STI 2020 ITB. I made this blog to help you guys out about embedded system especially setting up ESP32 to have some conditions. At this time, I am going to show you how connecting ESP32 to BMP280 sensor and OLED for serial communication. *DON'T YOU KNOW??* Besides using serial monitor that served by Arduino UNO, we can see the information between data processing peripherals by Serial Communication Protocols, here are several types of it. Inter- Intergrated Circuit (I2C) Half duplex, serial data transmission used for short-distance between board, modles and peripherals. Uses 2 pins Serial Peripheral Interface (SPI) Full duplex, serial data transmission used for short-distance between devices. Uses 4 pins. Universal Asynchronous Receiver- Transmitter (UART) Asynchronous, serial data transmission between devices. Uses 2 pins. In this tutorial, I'm going to show you how to connect I2C communi
