Introduction: Getting Started of Arduino Kit (Absolute Beginner)
Hi Guys ,the Arduino Starter Kit provided by ElecFreaks (focused on Open hardware 4 years) is a great material to get users into learning step-by-step conveniently. For this kit, there is no need for soldering, plug then use, the construction of the working circuit can be done within one minute. It has 9 courses in total, content includes LED, infrared sensor, servo, and IR remote control. 16 modules total price about 75usd, this kit save to 59.98usd.
The kit uses the Freaduino UNO, which is the improved version of the official UNO and 100% compatible with Arduino. It provides easy-to-use brick sensor interface, 3.3v or 5v IO switch, power supply with DCDC circuit which support MAX 2A etc.

Step 1: Step1. Arduino Start Blink
<p>/*<br> PART1 ARDUINO START Blink
Turns on LED for one second, then off for one second, repeatedly.
Get the code from: Arduino IDE->File->Example->Basics->Blink
Pin 13 has an LED connected on most Arduino boards.
*/
int led = 13;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}</p>Step 2: Step 2. Button Control LED
<p>/*<br> PART2 BUTTON CONTROL LED
Press the button, led ON, press again led OFF
*/
int led = 5; // The D5 pin,driving LED
int button = A0; // The A0,read the button,Here used a analog pin as digital pin.
void setup() {
pinMode(led, OUTPUT); // initialize the LED pin as an output.
pinMode(button, INPUT_PULLUP);// initialize the BUTTON pin as an input.
}
void loop() {
if(digitalRead(button)==LOW){
delay(200); // wait for 200 microsecond,Avoid pressing the button and read many times in this very short time
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
while(1){
if(digitalRead(button)==LOW){
delay(200);
digitalWrite(led, LOW); // turn the LED off (LOW is the voltage level)
break; //End of the while loop,Back to the main loop
}}

/*
PART3 Vibration sensors CONTROL Passive buzzer Knock on the table, the buzzer will ring */ int vibration = A0;// The A0 pin,read Vibration sensors int buzzer = 6; // The D6 pin,driving the Passive buzzer,the pin must PWM pin(3 5 6 9 10 11 on UNO) void setup() { pinMode(vibration,INPUT_PULLUP);// initialize the vibration pin as an input. pinMode(buzzer,OUTPUT); // initialize the buzzer pin as an output. } void loop() { if(digitalRead(vibration)==HIGH){ analogWrite(buzzer,200); //driver Passive buzzer must PWM,so analogWrite,200 is PWM value,max 1024 delay(1000); //wait for 1000 microsecond analogWrite(buzzer,0); //turn off the buzzer } }
Step 4: Step 4:PIR Sensor Control Motor Fan
/*
}
PART4 PIR Sensor CONTROL Motor fan If someone passing from the front, the fan will turn */ int pir = A0; // The A0 pin,read PIR int motor = 6; // The 6 pin,driving the motor void setup() { pinMode(pir,INPUT);// initialize the PIR pin as an input. pinMode(motor,OUTPUT);// initialize the motor pin as an output. } void loop() { if(digitalRead(pir)==HIGH){ digitalWrite(motor,HIGH); delay(5000);// wait for 5000 microsecond digitalWrite(motor,LOW); //turn off the motor }
Step 5: Step 5:LDR Sensor Control Motor Fan
/*
PART5 Photodiode sensor CONTROL Motor Fan According to the intensity of light motor speed control */ int photodiode= A0; // The A0 pin,read Photodiode int motor = 6; // The 6 pin,driving the motor void setup() { pinMode(photodiode,INPUT);// initialize the photodiode pin as an input. pinMode(motor,OUTPUT); // initialize the motor pin as an output. } void loop() { int speed=analogRead(photodiode)/2;//because the read max value is 512 analogWrite(motor,speed);//According to the intensity of light motor speed control }
Step 6: Step 6:Soil Moisture Sensor Auto Watering
/*
PART6 Soil moisture Sensor CONTROL Relay According to the intensity of light motor speed control */ int soil= A0; // The A0 pin,read Soil moisture int relay = 6; // The 6 pin,driving the Relay void setup() { pinMode(soil,INPUT);// initialize the soil pin as an input. pinMode(relay,OUTPUT);// initialize the relay pin as an output. } void loop() { int value=analogRead(soil); if(value>200){//set the default value ,you can set it then more or less to do something digitalWrite(relay,HIGH);//turn on the relay } else digitalWrite(relay,LOW);//turn off the relay }
Step 7: Step 7:Encoder Sensor Control Servo
/*
PART7 Encode Sensor CONTROL Servos Turn the rotary encoder control servos */ #include int encodeB= A0; // The A0 pin,read encodeB int servos = 6; // The 6 pin,driving the servos Servo servo; //Get a servo controller int angle=90; //set the servo angle void setup() { pinMode(encodeB,INPUT);// initialize the encodeB pin as an input. servo.attach(servos); attachInterrupt(0,start,FALLING);//set encodeA interrupt,this board interrupt0 is pin 2 } void loop() { } void start(){ if(digitalRead(encodeB)==HIGH){ angle-=30; }else angle+=30; if(angle>=180)angle=180; else if(angle<=0)angle=0; servo.write(angle); }
Step 8: Step 8: Display Temperature and Humidity
/* Part 8 USE DHT11 Temperature and humidity sensor and Segment
* display Temperature and humidity*/ #include "DHT11.h" //load Temperature and humidity sensor library #include "TM1637.h"//load Segment display library #define CLK 4//pins definitions clk for TM1637 #define DIO 5//pins definitions dio for TM1637 TM1637 tm1637(CLK,DIO);//get Segment display controler DHT11 dht11(A0);//DHT11 A0 void setup(){ tm1637.init(); tm1637.set(BRIGHT_TYPICAL);} void loop(){ dht11.start(); tm1637.display(3,12);//Temperature Unit tm1637.display(2,(dht11.DHT11data)[2]%10); tm1637.display(1,(dht11.DHT11data)[2]%100/10); delay(1000); tm1637.clearDisplay(); tm1637.display(3,(dht11.DHT11data)[0]%10); // humidity tm1637.display(2,(dht11.DHT11data)[0]%100/10); delay(1000); }
Step 9: Step 9 :Display Number of IRremote
Note: If you used IRremote.h on 1.6.5 ,which need change RECV_PIN = A0 . That's why we do not recommend.
/* Part9 USE IRreceive and IR remote Displayed on the segment code */
#include //load IRremote library #include "TM1637.h"//load Segment display library #define CLK 4//pins definitions clk for TM1637 #define DIO 5//pins definitions dio for TM1637 TM1637 tm1637(CLK,DIO);//get Segment display controler IRrecv ir(A0);//an instance of the IR receiver object,A0 is IRreceive pin; decode_results result; // container for received IR codes long codes[10]= // this array is used to store infrared codes { 0xFD708F,0xFD08F7,0xFD8877,0xFD48B7,0xFD28D7,0xFDA857, //0 1 2 3 4 5 0xFD6897,0xFD18E7, 0xFD9867,0xFD58A7}; // 6 7 8 9 void setup(){ tm1637.init(); tm1637.set(BRIGHT_TYPICAL); ir.enableIRIn();} void loop(){ if(ir.decode(&result)){ int i=-1; while(!(i>9||result.value==codes[++i])); ir.resume(); // resume receiver if(i<10){ tm1637.clearDisplay(); tm1637.display(3,i);//IRremote value }}}
