Jan 16, 2011 · Arduino have 6 analog pins labeled as Analog 0 to 5. Analog pins are mostly used to read analog sensors and sent to the 6 channels Analog Digital Converter (ADC). The ADC will convert the voltage (0V to 5V) to integers from 0 to 1023 (10 bit resolution). The Arduino Shield connectors are a hybrid of R2 and R3 configurations. They have the added SDA and SCL pins of R3 on one side, but do not have R3's IOREF and unused pin on the other. The power selection jumper duplicates the job of the IOREF pin, only it is a manual setting rather than automatic. Arduino Leonardo Compatible Board Features

Oct 05, 2018 · Connect the SDA pin to the I2C data SDA pin on your Arduino. On an UNO & '328 based Arduino, this is also known as A4, on a Mega it is also known as digital 20 and on a Leonardo/Micro, digital 2 Connect the WAKE pin to the ground. This sensor uses I2C address 0x5A. The STATUS pin is used to indicate the operation status of BG96 module. It will output HIGH level when the module is powered on. SCL,SDA: SCL,SDA: I2C Serial Data for Accelerometer and Temperature&Humidity Sensor. 10,9: AT_TX, AT_RX: These pins function as UART communication for module. 8: RI: When BG96 has URC to report, RI signal will wake up the host.

Jun 12, 2018 · Interfacing Arduino with SSD1306 OLED and DHT11 sensor: Circuit connections are shown below where: SSD1306 OLED GND goes to Arduino GND (ground) SSD1306 OLED VDD to Arduino 5V SSD1306 OLED SDA pin (serial data) to pin A4 (Arduino UNO I2C SDA pin) SSD1306 OLED SCK pin (serial clock) to pin A5 (Arduino UNO I2C SCL pin) Then connect the digital pin 5 of Arduino to the D4 of LCD module. Then connect the digital pin 4 of Arduino to the D5 of LCD module. Then connect the digital pin 3 of Arduino to the D6 of LCD module. Then connect the digital pin 2 of Arduino to the D7 of LCD module. And finally connect the 3.3V of Arduino to the A of LCD which is the anode of ...
