What is SDA and SCL?
SCL is the clock line. It is used to synchronize all data transfers over the I2C bus. SDA is the data line. The SCL & SDA lines are connected to all devices on the I2C bus. There needs to be a third wire which is just the ground or 0 volts.
What is SDA and SCL pins?
Arduino boards to share information with each other. The I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) that the Arduino Master board pulses at a regular interval, and a serial data pin (SDA) over which data is sent between the two devices.
Which Arduino has most Io?
The board with the most pins is the Mega 2560, which comes in with a whopping 54 Digital I/O pins (were 15 of them have PWM) and has 16 Input Analog pins.
What are the input and output pins of Arduino Mega?
