How to Display Images on OLED Using Arduino: Hello there fellow learners, in one of our previous blog on OLED, we learnt how to wire and code OLED. We also learnt to display simple text using Arduino code. So today in this blog, we will learn how we can
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...

OLED display: The display will have twoSDAandSCLpins. Connect these to the NodeMCUsD2andD1pins respectively. DHT11 Sensor: Connect this to NodeMCUsD4pin. MQ-135 Sensor: Connect this to NodeMCUsA0pin. PIR Sensor: Connect this to NodeMCUsD3pin. ...
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
You can also go one step further and display the time on your OLED screen after reading it from DS3231. For this, you need to install theAdafruit GFX SSD1306 libraryin Arduino IDE. Once installed, connect the ESP32 with the OLED and RTC module in the following configuration. ...
