Picked at random: The SiLabs Si7210 [1] is a Hall effect magnetic sensors with 0.1% linearity and an I2C interface, no Arduino ADC to tame. The Si7210 tops out at 0.2T. Eval bords for the series ...

In this project, we will learn how to design ECG Display using Pulse Sensor with OLED & Arduino. We will use 0.96″ OLED Display with 128x64 resolution for BPM & ECG waveform display. The I2C OLED uses ...

The magnetic compass has been a crucial navigational tool for around a thousand years or so, perhaps longer. While classical versions still work perfectly well, you can now get digital magnetometer… ...

In the Arduino IDE, go to the Library Manager, search for LIS2DML library and install it. Next, search for U8G2 library and install it as well. Now you can begin the coding by including the above ...

Code for Arduino, Heartbeat Sensor and OLED Interfacing. The complete code for the project is as follows. You can copy, paste and upload the code on your arduinp board. #include <Adafruit_SSD1306.h> ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

OLED screens can function as quantum sensors to map magnetic fields, allowing smartphone users to detect defects. ... Smartphone and TV Screens Become Magnetic Field Mappers with OLED Technology.
