For the Arduino Uno R4, this library defines two I2C buses. The first, "Wire" is configured for the SDA/SCL pins on the pin header, where "Wire1" is configured for the Qwiic connector.

This Arduino sketch demonstrates how to use an I2C-enabled LCD display with an Arduino board. The LiquidCrystal_I2C library is used to control the LCD, and the sketch also includes a function to ...

[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 … ...

By having the ADC range match the sensor range of interest, we make greatest use of the ADC resolution. A design consideration for this architecture is that an internal PWM frequency needs to be much ...

A new fully featured Arduino development board has been created called the Prestissimo Uno+ which is now available to back via Kickstarter with earlybird pledges available from just $20, AUS$28 or ...

The 12-bit MCP3221 analog-to-digital converter (ADC) incorporates an I2C interface in an SOT-23 package. The 400-kHz clock rate of the two-wire serial, I2C interface enables ...

Using the Arduino ADC and DAC features to realize a full-fledged multichannel anayzer with only a few common components allowed to operate a used NaI scintillation counter (from Ebay) and compare the ...

Electronic engineers, developers and hobbyists looking for a fully featured Arduino Mega compatible PLC may be interested in a new Indiegogo campaign ...

This paper presents the implementation of the I2C controller on FPGA for interfacing a low-cost ADC with an on-chip I2C bus interface. The objective of the I2C controller core is to establish and ...
