ENGR 7B Lecture Notes - Lecture 1: Computer Language, Semicolon, Error Bar
ENGR 7B – Lab – Intro to Arduino
IDE
• Integrated Development Environment
• Text program allowing you to write code to instill in Arduino
• Opening up Arduino program = opening up IDE
• Job includes taking human readable code we write and converting it into
commands the computer can follow (machine-readable)
o This job is called compiling
Sketch
• When you save a file in Arduino, it is called a “sketch”
o Contains all the computer code that you’ve written
o File extension is “.ino”
▪ Used to be “.pde”
Language
• Very similar to C++
• Basic concepts are exactly the same
• Code written will be human-readable
o Will be organized for humans to follow with ease
IDE Interface
• All default sketch names are “sketch_date”
o Ex: sketch_jan12a
o Ex: sketch_dec19b
o How to change?
o Go to save and change name
▪ Note you cannot have spaces in name of Arduino program
▪ Ex: Hello World = not accepted
▪ Ex: Hello_World = valid
• Buttons
o Verify = checks the code for any messages and displays errors on bottom
screen
o Upload = uploads code onto the Arduino board
▪ How to know if it’s working?
• When plugged in, two LEDs will be blinking very fast
• Tx and Rx
o Transmit and receive
o Serial Monitor = opens up serial monitor window and allows you to see
connection between computer and Arduino
