This library allows you to communicate with I2C / TWI devices. On the Arduino boards with the R3 layout (1.0 pinout), the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. The Arduino Due has two I2C / TWI interfaces SDA1 and SCL1 are near to ...
Which pins to use for this differs on some arduino models, but on the UNO and NANO you use pin A4 (SDA) and A5 (SCL). If you’re using another arduino, google the pinout and look for SDA and SCL pins. (For example, google “arduino mega pinout”, and check the images). I firs...
I2C is a very popular communication protocol. In the Grove system, I2C is used by 80+ sensors for communication, 19 of which are related to environmental monitoring. Today more and more MCUs uses 3.3V communication levels, but the traditional Arduino Uno still uses 5V, which leads to many m...

How to set up multiple sensors connected to one Arduino Uno? You can connect several sensors to a single I2C bus. Exact maximum amount depends on many factors, mostly on the wiring length. To have several sensors working on a bus, you have to assing an individual address to each sensor....

Here an Arduino Uno or Arduino Nano is used.You simply connect the device to the I2C pins on your Arduino. If you don't use the default I2C pins then Arduino software will use a bit banged (slower) method to control the device. This means you can have more than one I2C bus on a ...
This Stemma QT breakout makes all that frustration go away - solder in any 'standard' PEC11-pinout rotary encoder with or without a push-switch. The onboard microcontroller is programmed with our seesaw firmware and will track all pulses and pins for you
