This is the Sensirion SFM3304 library for Arduino allowing you to communicate with a SFM3304 sensor over I²C. Click here to learn more about the Sensirion SFM3304 sensor. The default I²C address of ...

Some Arduino Uno models have separate SDA and SCL pins and you can use them instead of the two analog pins if you wish. On a side note, I incidentally noted that MCP9808 is available in two address ...

Arduino basic library for XGZP6897D I2C differential pressure sensor from CFSensor Associated with a pitot tube, a differential pressure sensor is the basis for an airspeed sensor. This library was ...

[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino … ...

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

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 ...

Use an ATtiny85 to display sensor values on an I2C LCD (equiped with PCF8574): GY21P (Si7021+SHT21) I2C sensor, temperature and relative humidity DS18b20 Dallas sensor, one wire, temperature I had ...
