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 ...
Arduino Uno/Nano example pinsconstuint8_tdPinIn =12;//any pin; connect switch against GND and +V (or use only GND and INPUT_PULLUP below)constuint8_tdPinOut =13;//any pin; connect LED with resistor or just use 13 = LED_BUILTIN on Uno/Nanoconstuint8_taPinIn =14;//needs analog...
The pinout for the DIP version and SO16 (SMD) are identical: [Source: Datasheet] PCF8591 Inputs Thefour ADC channels can be configured as single ended or differential inputs. For single ended input, these work the same as an Arduino ADC input i.e. they measure the input signal compared...
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....

Uses a standard I2C pinout Raspberry Pi I2C and Arduino I2C Ref:Arduino Project Hub I2C is also used and compatible with the Raspberry Pi and Arduino to allow data exchange between microcontrollers and peripherals with a little wiring. Raspberry Pi = It’s a low-cost, credit-card sized comput...
The sensor expansion board fits on STM32 Nucleo Arduino Uno compatible header as shown. Ensure that the sensor expansion board is installed correctly. With this setup, I2C clock line (SCL) gets connected to PB8 (D15) I2C data line (SDA) g...
