Code that
touches the
real world.
A hands-on Arduino + Processing curriculum. Wire sensors, write firmware, stream live data to your screen — and build a weather station, a radar and a self-watering garden along the way.

Two foundations.
Five real projects.
Each module has learning objectives, vocabulary, step-by-step labs with tested code, interactive simulators, levelled exercises with solutions, and a self-check quiz.

First Steps with Arduino
Make a microcontroller do something real — in under ten minutes.
Processing — Real-Time Visualization
Turn raw sensor numbers into live graphics on your screen.

Temperature & Humidity — DHT11
Build a mini weather station that streams live climate data.

Light Sensor — Photoresistor (LDR)
Read the brightness of the room and paint it on screen.

Sonar — Ultrasonic Sensor HC-SR04
Measure distance with sound and build a working radar screen.

Arduino Ohm Meter with Processing Display
Turn your Arduino into a measuring instrument.

Automatic Irrigation System
A plant that waters itself — sensing, deciding and acting.
The Workbook
All 42 exercises in one place. Filter by level and type, track what you’ve finished.
One pipeline.
Every project.
Learn it once in the foundations, then recognise it everywhere: a sensor measures, Arduino sends a line of text, Processing parses it in serialEvent() and draws it in draw().
Learn by doing. Check yourself. Level up.
Clear objectives
Every module opens with “by the end you can…” goals and a vocabulary list.
11 simulators
Blink, map(), voltage dividers, sonar echo, radar, ohm meter, irrigation — try before you wire.
42 levelled exercises
Predict, calculate, build, code, debug and design tasks — Basic to Challenge, with hints and solutions.
Self-check quizzes
36 questions with instant feedback and explanations. Your best score is saved locally.
Safety first
Clear rules for electricity, water and power supplies — written for the classroom.
10 code corrections
Every sketch from the original was reviewed; bugs and inconsistencies fixed and documented.
Cross-curricular
Physics, maths, biology and art links make every project count in more than one subject.
Works offline
A static site with a one-click launcher — run it from a USB stick in the lab, no internet required.
Every circuit, documented.
The original handbook, upgraded for students.
We kept every lab from the Digital Challenge handbook and added the scaffolding high-school learners need: objectives, vocabulary, worked maths, safety notes and a full answer key.
