23 How IoT Sensors are connected?

24 GPIO Separate line for each Sensor GPIO_C GPIO_B GPIO_A SoC Sensor A Sensor B Sensor C GPIO pins are especially good to use when programming simple sensors or actuators which only require single data line. For example: LEDs, Relays, Buzzers, Buttons, Passive Infrared sensor (PIR) Many more!

I2C Shared line for all Sensors SCL (clock) SDA (data) SoC Sensor A Sensor B Sensor C I2C pins are especially good to use when programming more complex

25 I2C Shared line for all Sensors SCL (clock) SDA (data) SoC Sensor A Sensor B Sensor C I2C pins are especially good to use when programming more complex sensors or actuators which require multiple data lines. For example: Ultrasonic sensors, Stepper motors and servos, LCD screen, LED matrices Many more!

26 Why IoTDK is good?
