5.1. A basic understanding of the Arduino Robot

In this article, I would like to explain a basic understanding of the Arduino Robot.





1. Hardware composition

The Arduino Robot is composed of two boards and two wheels.
The upper board is the Control Board, the lower board is the Motor Board.

2. I/O equipment

The Control Board and the Motor Board has some I/O equipment as follows.

	Board	I/O	Items
	Control Board	Input	I2C
			Knob
			Control Pad
		Output	LCD
			LEDs
			Speaker
	Motor Board	Input	IR Sensors
			I2C

Control Board I/O equipment

Motor Board I/O equipment

3. Control Board I/O Pins

Control Board has some pins as follows.

Control Board TK/TKD pins

・TK0 to TK7 pins
　TK pins are used as analog input for sensors, like distance sensors, analog ultrasound sensors.


・TKD0 to TKD5 pins
　TKD pins are used as digital I/O. A HIGH or a LOW voltage value can read/write through pins.



4. Motor Board I/O Pins

Motor Board has some pins as follows.

Motor Board B_TK pins

・B_TK1 to B_TK4 pins
　B_TK pins are used as analog/digital inputs.
　A HIGH or a LOW voltage value can read/write through pins.


For now, I just want to know these TK/TKD/B_TK pins play a role in analog/digital I/O pins.

I'll describe later about the details of these pins.



5. For more details about the Arduino Robot

The Arduino Robot has some other features. If you want to know these details, please refer to the Arduino official website.



In this article, I explained a basic understanding of the Arduino Robot. I would like to explain how to try some samples of the Arduino Robot in the next article.
