In this workshop, you’ll build simple circuits and write a little code to make lights and sensors do fun things. You’ll start with one blinking LED, then try a sensor that “notices” light. By the end, you’ll know how to:
- Plug parts into a breadboard
- Connect to the Arduino the right way
- Upload code and see your project come to life
You don’t need experience. We’ll go step by step.
Quick safety rules:
- Unplug the USB cable before moving wires.
- If something gets hot or smells weird, unplug right away and ask for help.
- Do not connect an LED straight from 5V to GND without a resistor.

Safety First
Electronics are safe when you go slow and double-check your wires. If you are not sure, ask a staff member before plugging in.
Circuit Safety
Introduction to the Arduino and Components
In this step, you’ll get to know the Arduino and the parts you’ll use today. We’ll build circuits with LEDs and a breadboard.
Getting to know Arduino
Make a basic LED circuit
Use a breadboard to connect your components
Getting started with Arduino
In this step, you’ll open the Arduino app, plug in your board, and upload your first program to make an LED blink.
Getting Started with Arduino IDE
Connect LED to Arduino
Adding two LEDs
Adding & Reading Sensors
A sensor helps your Arduino notice the world (like light or touch). In this section, you’ll use a sensor and make your Arduino react.
Working with Sensors
Using the Serial Monitor
Optional: Additional Sensors
These are extra challenges if you finish early. Pick one with a staff member.
