Goal
Produce “time;value” lines usable in a spreadsheet.
Why it matters
A clean data format turns an experiment into an analysable result.
What you need
- Arduino UNO board
Nothing to buy: every component below is simulated in the browser.
Steps
- 01Print a header once inside setup().
- 02Every second, print millis() then the reading, separated by a semicolon.
- 03Check there is no stray space or text.
This tutorial runs inside the Circuitly simulator: your wiring and your code are checked automatically at every step.
Frequently asked questions
- Do I need to buy hardware for this tutorial?
- No. Everything runs in the browser: Circuitly simulates the board, the components and the code. Real hardware is optional if you want to rebuild the circuit afterwards.
- Which components are used?
- Arduino UNO board. They are already available in the simulator library.
- How long does it take?
- About 15 minutes, intermediate level, in 3 guided steps.
- What should I know before starting?
- The previous tutorial in the series, “Control the board from the keyboard”, is enough preparation. No software install is required.
- Is the code provided and checked?
- The simulator checks your wiring and your code automatically at every step, and shows the commented solution if you get stuck.
