ESP32 connect OLED display ( SSD1306 )

ESP32 connect OLED DisplayWe have ESP32 WiFi Module and We'd like to connect to some small display.Easy way to interface with small display is OLED on I2C Bus. because of use 4 wire to connect.We choose to OLED is  0.96 inch 128x 64 OLED  and SSD1306 Library from Adafruit.and we test on Nano32 development board from Gravitech and Maker Asia.Wiring DiagramOLED SSD1306 Pin SCL  to  ESP32 GPIO 22OLED SSD1306 Pin SDA  to  ESP32 GPIO 21IDE and  LibraryWe use [...]

ESP8266 Weather Station with Color TFTLCD

ESP8266 Weather Station with TFTLCDIn this project, we'll learn how to make a weather station using an ESP8266 WiFi Module and a 2.2" TFT LCD display. ( 240 x 320 65K)This project pulls weather data using the Wunderground API. It displays the date, time, current weather conditionals, 4-day forecast and even moon phases.HardwareESP8266 WiFi Module ( ESP8266 DevKit or NodeMCU )TFT LCD 2.2 Inch  : TFT01-2.2SP from Electrofreak (SPI Bus )Wiring DiagramTFT LCD Pin VCCTFT LCD [...]
