Intro

Membuat alat pemantau quota 4G berbasis IoT.

Goal

Menampilkan sisa quota internet pada paket modem bolt realtime berbasis IoT

Gear

-PC dengan PHP server (saya menggunakan wamp)
-ESP8266 (saya menggunakan versi esp-01)
-LCD 16x2 (dengan i2c backpack)
-FTDI loader
-Jumper Wire
-Breadboard/Prototypeboard
-Wifi Network

Flowchart

Gambar 1. Flow Chart

Gambar 2 FTDI + ESP-01 + LCD 16x2

Code

Pada Server
-Menggunakan Library DOM Simple Parser http://simplehtmldom.sourceforge.net/

Pada ESP8266
-Wiring Flash

Gambar3. Wire Map Flash

ESP8266 - FTDI
VCC     - 3.3V
GND     - GND
RX      - TX
TX      - RX
CH_PD   - 3.3V
RST     - PUSH BTN - GND
GPIO0   - GND (FOR FLASH, 3.3V FOR RUNNING)

Gambar4. Wiring ESP-01 to LCD

ESP8266 - i2c 16x2 LCD BACKPACK
GPIO2   - SCL
GPIO0   - SDA
GND     - GND

LCD 16x2 = 5V
ESP8266-01 = 3.3V

-Menggunakan Library LiquidCrystal i2C https://github.com/agnunez/ESP8266-I2C-LCD1602

Note

- ESP-01 menggunakan tegangan 3.3V, dan LCD 16x2 menggunakan 5V
- ESP-01 i2c SDA=GPIO0, SCL=GPIO2
- LiquidCrystal i2C library https://github.com/agnunez/ESP8266-I2C-LCD1602
- buat file cookies.txt pada direktori server
- pada server CURL telah terinstall & enable
- DOM Simple Parser Library http://simplehtmldom.sourceforge.net/
- DOM Simple Parser install pada ./lib/dom/

1. LiquidCrystal_I2C library

https://github.com/agnunez/ESP8266-I2C-LCD1602

Download+extract arduino - libraries folder - restart arduino ide

2. Set Dev Board
-Pick Board Generic ESP8266 Module

3. Try burn/flash/upload

Files - Example - LiquidCrystal i2C - Hello World
Verify - Upload

4. Wire MAP

Cheat Sheet ESP8266-01

ESP8266 - FTDI
VCC - 3.3V
GND - GND
RX - TX
TX - RX
CH_PD - 3.3V
RST - PUSH BTN - GND
GPIO0 - GND (FOR FLASH, 3.3V FOR RUNNING)

ESP8266 - i2c 16x2 LCD BACKPACK
GPIO2 - SCL
GPIO0 - SDA
GND - GND

LCD 16x2 = 5V
ESP8266-01 = 3.3V

Catatan:
- 3.3v ≠ 5v
- selesai upload  GPIO0 dicabut + reset (agar supaya mode flash off)
