2. How to use

In this chapter, we will introduce the basic operations of ArduinoIDE in the section 2.1,

including custom library importation, program compiling and uploading. The detailed

operations and experiments of the devices on the board are presented in the section

2.2. The development board we used here is Arduino UNO PLUS. For more detailed

information about this development board, please refer toAppendix.

2.1 Arduino IDE

2.1.1 Library importation

Here we take the Arduino 1.0.6 (free installation) as an example to illustrate how to

import libraries. Firstly, start the software arduino-1.0.6.exe.

Then, click File -> Preferences, to enter the configuration interface.

Accessory Shield User Manual Waveshare

V1.1.6, March 10th 2015

Find out the folder libraries, and copy it to the folder pointed by the option

Sketchbook location:

Restart the software, and then click Sketch -> Import Library, to check the library

options: adxl345,ds3231,lm75,rgb_p9813 and ssd1306. If all of them are

available, the libraries are imported successfully.

2.1.2 Program compiling and uploading

1) Switch the BOOT mode of UNO PLUS development board to OFF, and set

VCC to 5V;

2) Connect the Accessory Shield module to the UNO PLUS development board,

and then the development board to your PC via a USB cable. You can see the

power light on the module lights up when the module is working properly.

3) This document presents the method of program compiling and uploading with

the Demo provided by Arduino IDE. Click File -> Example -> 01.Basics -> Blink,

to open the Demo.

V1.1.6, March 10th 2015

4) Click Tools -> Board -> Arduino Uno, to select relative Arduino development

board. Since the setting will be saved automatically, you only need to configure

it once.

5) Click Tools -> Serial Port -> COM4, to configure the serial port of the Arduino

development board for uploading. Please take a note that the port number in

used is various with different PCs, so you need to check the actual serial port

number by Device Manager before making the setting. In here, the serial port

number is COM4.

6) Click the button to start program compiling. If there is no error, the

software will give a prompt “Done compiling” and display the size of generated

file.

7) Click the button to start uploading. When finished, you can see the LED

on the UNO PLUS development board blinking in a frequency of 1Hz if the

Accessory Shield User Manual Waveshare

V1.1.6, March 10th 2015

program runs properly.

2.2 Basic experiments

Please make sure the libraries in the Demo are imported correctly, before

performing the basic experiments presented in the sections below.

2.2.1 5-way joystick

The Joystick has 5 action statuses: UP, DOWN, LEFT, RIGHT and ENTER. The

keys relative to different statuses are connected to corresponding Arduino pins. The

key-press can be judged by checking the corresponding IO levels.

Operation and phenomena:

Perform program compiling and uploading, and then click the button to start

the serial port monitor of Arduino IDE. If the program is running properly, the

on-board LED will blink in the frequency of 1Hz, indicating that the whole system

works well. When any key is pressed, the monitor will show the one has been

pressed, for example: you press UP, as the figure shows below.

2.2.2 Adjustable potentiometer

ATMEGA328P-AU is the main control chip of UNO PLUS development board. It has

a wide power voltage range, supporting 3.3V and 5V power supply. With a 10-bitAD

converter embedded, it can provide 2^10=1024 levels of AD conversion. For 3.3V

power supply, the resolution is up to 3300mv /1024 = 3.22mv.When theAD value is

1, it corresponds to the output voltage 3.22mv. For 5V power supply, the resolution

Accessory Shield User Manual Waveshare

V1.1.6, March 10th 2015

is 5000mv / 1024 = 4.88mv. When the AD value is 1, it corresponds to the output

voltage 4.88mv.

Accessory Shield provides an on-board 10k adjustable potentiometer with the

maximum adjustable output voltage of 3.3V. When the development board is

powered supply by 3.3V, the ADC output value is in the range of 0 –1023. For 5V

power supply, the ADC resolution is 4.88mv, and the AD value corresponding to

3.3V, the maximum output voltage, is 3300 / 4.88 = 676, so the ADC output value is

in the range of 0 –676 in this case.

Operation and phenomena:

Perform program compiling and uploading, and then click the button to start

theserial port monitor of Arduino IDE. If the program is running properly, the monitor

will display the current ADC value. When the potentiometer is adjusted, the

outputted sample value will change too, as the figure shows below.

2.2.3 Buzzer

In applications, active buzzer can be directly connected to the rated power supply to

work properly. But passivebuzzer, as well as electromagnetic loudspeaker, requires

an audio output circuit to work with. The buzzer we use here is an active buzzer,

which can either perform simple frequency sound with DC power source, or play

simple music withAC power source.

Operation and phenomena:

Perform program compiling and uploading to the board. If the program is running

well, you can hear the buzzer play some simple music.

2.2.4 RGB LED

RGB LED use PWM function to control the brightness generated respectively by

Accessory Shield User Manual Waveshare

V1.1.6, March 10th 2015

three LED chips (R, G and B) embedded in the LED light. And the mixture of RGB

can display rich colors.

Operation and phenomena:

Perform program compiling and uploading to the board. If the program is running

well, you can see the RGB LED displays gradient colors.

2.2.5 Temperature sensor: LM75B

The LM75B is a temperature-to-digital converter with I2C interface. In a simple

application design, it only requires a decoupling capacitance to work with.And there

are three selectable logic address pins so that eight devices can be connected on

the same bus without address conflict.

It has the following features:

Pin-for-pin replacement for industry standard LM75 and LM75A;

I2C-bus interface with up to 8 devices on the same bus, frequency range from

20 Hz to 400 kHz with bus fault time-out to prevent hanging up the bus;

Power supply range from 2.8 V to 5.5 V;

Temperatures range from -55℃to 125℃;

11-bit ADC that offers a temperature resolution of 0.125℃;

Temperature accuracy of:

±2℃from -25℃to +100℃;

±3℃from -55℃to 125℃;

Supply current of 1.0A in shutdown mode for power conservation;

ESD protection.

When LM75 servers as a slave, a 7-bit slave address is used.

1= HIGH, 0= LOW

MSB

LSB

The pins A2/A1/A0 of this module are tied to Ground, so the slave address is 0x48

in here.

Operation and phenomena:

Perform program compiling and uploading, and then click the button to start

theserial port monitor of Arduino IDE. If the program is running properly, the monitor

will display the current temperature value. Touching LM75 with your hand, you can

see that the outputted sample values change too, as the figure shows below.
