First thing we need to do is complete the connections. Connections are very simple, just 4 wires, SCL, SDA, VCC and GND. We just have to connect SCL to SDA and SDA to SCL of Arduino and power pins to VCC and ground of Arduino. Connections for OLED to Arduino Vcc - 5V Gnd - Gnd...
接线很简单,只需要 4 根杜邦线。屏幕的 4 个引脚和 Arduino 按照下面的表格接好即可。 Vcc – 5V Gnd – Gnd SDA – SDA SCL – SCL 准备程序框架 打开Arduino IDE 如果是首次使用 OLED,需要通过 sketch 菜单、include library、manage library 选项安装代码库。搜索名为 SSD1306 和 Adafruit GFX 的库,通过...
Step2: Find the address of the OLED Display. For that upload the following code in Arduino. Then open the serial monitor and note the address of the OLED display. Connect only the OLED display to the Arduino, do not connect the RTC module. Otherwise, you will get three addresses. #includ...
Make connections as shown. Make sure you connect Ground Pin of RFID reader to Ground Pin of Arduino. I am using the SoftwareSerial Library of Arduino which enables digital pins to be used in serial communication. I have used pin 9 as the Rx of Arduino. (You can also use the hardware R...
How to Add an E-Ink Display to Your Project: Lots of projects involve monitoring of some kind of data, such as environmental data, often using an Arduino for control. In my case, I wanted to monitor the salt level in my water softener. You might want to
Untitled ESP32-C3 board with 0.42″ OLED display Onboard display (the cutest thing ever): 72×40, I2C (SCL: 5, SDA: 6) Onboard LED: GPIO 8 Note: The display on this board seems to work better with Arduino IDE (select “ESP32C3 Dev Module”) rather than MicroPython. Use the u8g...
Make a weather station by connecting sensors that return Pressure, Humidity and Temperature. Display the results on an OLED screen. Or make a robot by controlling some servo motors! (or a 3D printer). Much more... A microcontroller is a self contained processing unit with in built RAM, Fla...
To use this meter with an LCD screen, connect the LCD to your Arduino (seeHow to Set Up an LCD Display on an Arduinoif you need instructions). Pin 11 will be used for the LCD, so wire the capacitance meter using pin 8 instead of pin 11. Here’s the code: ...
ESP32: Guide for MicroSD Card Module using Arduino IDE If you want a specific datalogging example with sensors, we also have the following projects (you can easily modify the projects to use other sensors): Altimeter Datalogger: ESP32 with BMP388, MicroSD Card Storage and OLED Display ...
