1 BASIC ARDUINO WORKSHOP Mr. Aldwin and Mr. Bernardo 1

2 BASIC ARDUINO WORKSHOP Course Goals Introduce Arduino Hardware and Understand Input Software and Output Create simple project 2

3 Arduino Open-source electronics platform based on easy-to-use hardware and software. Reads inputs like sensor, button, text Create action as output by activating a motor, turning on an light, sending messages. 3

38 ARDUINO QUICK REFERENCE Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs like sensor, button, text and create action as output by activating a motor, turning on an light, sending messages. TINKERCAD.COM- ARDUINO AND ELECTRONIC SIMULATOR Built your project and test different electronic components including Arduino uno using Autodesk online simulator LEARN MORE USING EXAMPLE The open-source Arduino Software (IDE) makes it easy to write code and upload it to the board. It runs on Windows, Mac OS X, and Linux. The environment is written in Java and based on Processing and other open-source software. //this program blink LED at pin 13 void setup(){ pinmode(13,output); void loop(){ digitalwrite(13,high); //LED on delay(1000); //delay 1 second digitalwrite(13,low); //LED off HARDWARE DIGITAL INPUT digitalread(11); read whether it receive HIGH or LOW ANALOG INPUT analogread(a0) ; read voltage from 0-5 volts (A0-A5) ANALOG OUTPUT analogwrite(10, 0-255); give pwm signal (pwm 3,5,6,9,10,11 pins) Pulse Width Modulation or PWM, is a technique for getting analog results with digital means. Digital control is used to create a square wave, a signal switched between on and off. This on-off pattern can simulate voltages in Volts) between full on (5 and off (0 Volts) by changing the portion of the time the signal spends on versus the time that the signal spends off. Serial.println(analogRead(A0)); SERIAL MONITOR EXAMPLE //Program will read input and display to serial void setup(){ pinmode(10,input); Serial.begin(9600); //baud rate speed void loop(){ int button1=digitalread(10); Serial.println(button1); read analog pin A0 and display to serial DIGITAL OUTPUT PROGRAM //program to blink LED at pin 13 void setup(){ pinmode(13,output); void loop(){ digitalwrite(13,high); //LED on delay(1000); //delay 1 second digitalwrite(13,low); //LED off DIGITAL INPUT AND OUTPUT PROGRAM // program that reads input and turn on the LED void setup(){ pinmode(10,input_pullup); pinmode(13,output); void loop(){ int button1=digitalread(10); if (button1==1) { // button is pressed digitalwrite(13,high); //LED on else if (button1==0) { // button is not pressed digitalwrite(13,low); //LED off ANALOG INPUT AND OUTPUT (PWM) PROGRAM //LED dimmer or motor speed control void setup(){ pinmode(a1,input); pinmode(9,output); //pwm pin Serial.begin(9600); void loop(){ int button1=analogread(a1); Serial.println(button1); analogwrite(9,button1/4);
