Arduino Mega Mega2560 I2C on pins A4 and A5 for Arduino UNO shield ... No, the I2C is fixed to the specific pins for a ATmega2560 microcontroller. I can think of two things, perhaps someone else can think of a third one. You could try a software I2C library on pin A4 and A5. Here is a list of those libraries: Arduino I2C libraries · Testato/SoftwareWire Wiki · GitHub MegaQuickRef - ArduinoInfo Each of the 54 digital pins and 16 analog pins on the Mega can be used as an input or output, using pinMode (), digitalWrite (), and digitalRead () functions. The analog pins will sample voltage levels and report a digital value using analogRead (). Analog pins and a subset of the digital pins do Pulse Width Modulation (PWM) using analogWrite ().

Connect two I2C devices to Mega 2560 - Arduino The I2C bus is a 'bus'. Connect all the SDA together and all the SCL together. In the sketch (the software) you can select a device because every device has its own I2C address on that bus. Run to i2c_scanner to see if your wiring is okay, it will scan all the devices on the bus.

Arduino Mega - I2C pins (20/21) unreliable - Arduino Stack Exchange The I2C pins on the Arduino Mega 2560 board are 100% reliable, but you have to use them correctly. The Wire library could halt when something is wrong with the hardware I2C bus. In that case the sketch stops. The Wire library should have timeouts programmed in case something is wrong with the hardware, but sadly it doesn't have timeouts.

Arduino Mega Pinout - JavaTpoint There are 54 digital Input/Output pins from pin numbered from 0 to 53. The 15 pins from the digital I/O are PWM (Pulse Width Modulation) pins numbered from D2 - D13 and D44 - D46. The digital pins have the value either HIGH or LOW. SPI-SCK It stands for Serial Peripheral Interface.

Serial Communication between NodeMCU and Arduino This project is all about serial communication between ESP8266-12 (NODE-MCU) and Arduino. As we know ESP-12 have one analog pin where we can connect our analog sensor, But what else if we need more than one analog pin to connect more analog sensor and again if you want to send data to server like adafruit.io or your own server.

What data type are the analog pin labels (A0, A1, etc)? As you can see in Arduino.h, the analogRead () has uint8_t as parameter. You can define them as byte or uint8_t and you don't have to use the sizeof (). The type of A0 is defined in the file pins_arduino.h: #define PIN_A0 (14) static const uint8_t A0 = PIN_A0; Nevertheless, what you have with integers is 100% okay as well.
