💻 Set Up Your Computer
1. Install Arduino IDE
Go to arduino.cc/en/software
Download and install the version for your operating system
Once installed, open it up — we’ll return to this soon
2. Plug in the Arduino
Use the USB cable to connect the Arduino to your computer
The green light should turn on — this means it’s receiving power
3. Confirm It's Detected
In Arduino IDE, go to Tools > Port
You should see something like
COM3
or/dev/tty.usbmodem...
If it shows up, you’re good to go!
