Let's start to make something with arduino uno r3.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Prepare Your Development Kit Like Arduino Kit and Arduino IDE in Your Computer
- 1* Arduino Uno R3
- 1* Led
- 1* buzzer
Step 2: Make Circuit in Your Boar
led or buzzer has 2 pin. loger pin must connect to the high voltage(+) and another pin connect to loq voltage(-). in this case, high voltage is the thirteenth port and low voltage is the GND(ground) port. use dark cable for your GND and bright cable for high voltage
Step 3: Write Your Code
we can write code for arduino uno in arduino IDE using programing like C++. after you finish write your code, you can compile and upload your program from menu skecth and then upload. but before that, you must select your microcontroler tipe and port that using to conect for microcontroler. your code must contain function or method setup() and loop(). in setup() we declare or initialization variable that use in code. in loop() we write the function which will run.
