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...
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,通过库管理器下载并安装即可。 创建代码...
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...
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...

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...
To use this capacitance meter using the serial monitor for data output, connect the Arduino to your PC, open the Arduino IDE, and upload this code to the Arduino: const byte pulsePin = 2; const unsigned long resistance = 10000; volatile boolean triggered; ...
Step 1:Connect the Wio-E5 module directly to the “UART” slot of the Expansion Board. Step 2:Connect the DHT11 into the “A0/D0” socket as shown below. Software Preparation If this is the first time you work with Arduino, we strongly recommend you to seeGetting Started with Arduinobe...
How to use I2C to connect an LCD to the Raspberry Pi. Learn how to scroll, position, and clear text, print the date, time, IP address, and sensor data.
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 ...
