How I2C Talks on Two Wires
SDA, SCL, and device addresses explained.
Two Wires, Many Devices
I2C lets many chips share just two wires, so you can add sensors and screens without running out of pins. 🔌
Meet SDA and SCL
I2C uses two lines: SDA carries the data, and SCL carries the clock pulses that keep both sides perfectly in step.
