Page 16: Keyestudio Uno Development Board
(2)Keyestudio UNO Development Board You need to know that Keyestudio UNO development board is the core of this solar tracking device. Keyestudio UNO Development Board： This development board satisfy requirements microcontrollers. All you need to do is to connect it to a computer via a USB cable and power it by an external power supply of DC 7-12.
Page 17 Microcontroller ATMEGA328P-AU Operating Voltage Input Voltage DC7-12V (recommended) Digital I/O Pins 14 个 (D0-D13) 6 个 (D3，D5，D6，D9，D10， PWM Digital I/O Pins D11) Analog Input Pins 6 个(A0-A5) 32 KB (ATMEGA328P-PU) of Flash Memory which 0.5 KB used by bootloader SRAM 2 KB (ATMEGA328P-PU) EEPROM 1 KB (ATMEGA328P-PU)
Page 18 ICSP (In-Circuit Serial Programming) Header ICSP is the AVR, an Arduino micro-program header consisting of MOSI, MISO, SCK, RESET, VCC, and GND. It is often called the SPI (serial peripheral interface) and can be considered an "extension" of the output. In fact, slave the output devices under the SPI bus host.
Page 19 V Pins (VCC) Power the external sensors and modules. Select the voltage of 3.3V or 5V via a slide switch. Digital I/O It has 14 digital input/output pins, labeled D0 to D13 (of which 6 can be used as PWM outputs). These pins can be configured as digital input pin to read the logic value (0 or 1).
Page 20 Microcontroller Each control board has its own microcontroller. You can regard it as the brain of your board. Microcontrollers are usually from ATMEL. Before you load a new program on the Arduino IDE, you must know what IC is on your board.
Page 21 ATMEGA 16U2-MU USB to serial chip, can convert the USB signal into serial port signal. Slide Switch You can slide the switch to control the voltage of pin V (VCC), 3.3V or 5V. Voltage Regulator To control the voltage provided to the board, as well as to stabilize the DC voltage used by the processor and other components.
Page 22: Install Driver
You can supply an external voltage input DC7-12V through this pin to the board. Analog Pins The board has 6 analog inputs, labeled A0 through A5. Can also used as digital pins, A0=D14, A1=D15, A2=D16, A3=D17, A4=D18, A5=D19. For analog port, you can connect through female headers, or through pin headers (labeled S) of 2.54mm pitch.

7.Projects Now with all these preparations done, let’s start our projects. We will start from those basic projects involved only one single sensor or module and then move to a more intricate one , solar tracking, combining these components together. Note: (G), marked on each sensor and module, is the negative pole and connected to“G”, “...
Page 85 For the starter and enthusiast, this is a fundamental program---LED Blinks. LED, the abbreviation of light emitting diodes, consist of Ga, As, P, N chemical compound and so on. It is often applied to numbers and text display as an indicator in the circuit. The LED can flash diverse color by altering the delay time in the test code.
Page 86 USB Cable*1 (4) Connection Diagram： The pin -, + and S of LED module are connected to the pin G, 5V and D3 port of expansion board.

Page 88 //******************************************************************* (6)Test Results： After uploading the program, the LED blinks with the interval of 1s. (7) Code Explanations: pinMode(LED，OUTPUT) - This function can denote that the pin is INPUT or OUTPUT. digitalWrite(LED ， HIGH) -When pin is OUTPUT, we can set it to HIGH(output 5V) or LOW(output 0V).

Page 90: Project 2: Adjust Led Brightness
Project 2: Adjust LED Brightness (1) Description： In previous lesson, we control LED on and off and make it blink. In this project, we will control LED brightness through PWM to simulate breathing effect. Similarly, you can change the step length and delay time in the code so as to demonstrate different breathing effect.
Page 91 as 0 and HIGH as 1, and let the Arduino output five hundred 0 or 1 signals within 1 second. If output five hundred 1, that is 5V; if all of which is 1, that is 0V. If output 010101010101 in this way then the output port is 2.5V, which is like showing movie.

Page 94 (6) Code Explanation When we need to repeat some statements, we could use FOR statement. FOR statement format is shown below: FOR cyclic sequence: Round 1：1 → 2 → 3 → 4 Round 2：2 → 3 → 4 Until number 2 is not established, “for”loop is over, After knowing this order, go back to code: for (int value = 0;...
Page 95 We know that digital port only has two state of 0 and 1. So how to send an analog value to a digital value? Here,this function is needed. Let’s observe the Arduino board and find 6 pins marked“~”which can output PWM signals.
Page 96 In the above figure, the green line represents a period, and value of analogWrite() corresponds to a percentage which is called Duty Cycle as well. Duty cycle implies that high-level duration is divided by low-level duration in a cycle. From top to bottom, the duty cycle of first square wave is 0% and its corresponding value is 0.

As shown in the picture below, BH1750 is composed of a photodiode, an operational amplifier, an ADC acquisition, a crystal oscillator, etc.
Page 126 and then converted into a 16-bit binary number through the logic circuit and stored in the internal register (Note: The stronger the light, the greater the photocurrent, and the greater the voltage, so the intensity of the light can be judged by the value of the voltage. However, it should be noted that the voltage and the light intensity are one-to-one correspondence, but not proportional.

Project 9: Servo (1)Description： Servo motor is a position control rotary actuator. It mainly consists of housing, circuit board, core-less motor, gear and position sensor. Its working principle is that the servo receives the signal sent by MCU or receiver, and produces a reference signal with a period of 20ms and width of 1.5ms, then compares the acquired DC bias voltage to the voltage of the potentiometer and obtains the voltage difference output.

Page 134 servo is connected to Gnd (G), the red wire is linked with 5v (V), and the orange wire is connected to digital pin 9. When connecting the steering gear, an external power supply must be used. Because the current requirement for driving the steering gear is relatively large, and the current of the development board is far from enough.

Project 11： Solar Panel Device with Multiply Functions (1)Description: In previous projects, we just focused on a single function of a certain sensor or module. Can we combine them together and make a device which is able to display various functions? The answer is positive. And in this lesson, we will write a set of test code to make the solar tracking device perform all functions illustrated before.

And when the ambient light sensor detects changes in light intensity, servos rotate to the position where the light is the strongest and LCD1602 shows the value of the light intensity and temperature and humidity detected by the BH1750 and DHT11 respectively. We could push the button on the servo to adjust the accuracy of the angle to make it rotate faster.
