YEARS 12 & 13 · FRENCH STI2D
Understand.
Connect.
Program.
From a first indicator light to a connected beehive, learn to connect a need, a circuit and an Arduino program.
Start the introduction →6 lessons · 5 illustrated setups · 5 complete programs
Observe the beehive.
Understand the data.
UNO R4 WiFi + DS18B20
Explore the project ↗THE INFORMATION CHAIN
The supply provides energy to the system. A control pin carries information: it is not a power supply.
LEARNING THROUGH EXPERIENCE
One path, six steps.
Understand the board
Observe, identify and upload.
Open the lesson ↗01Year 12 · Digital outputControl an LED
An output, a current, a timing diagram.
Open the lesson ↗02Year 12 · Digital inputRead a logic state
Read a button and filter contact bounce.
Open the lesson ↗03Years 12 → 13 · ADC and PWMMeasure a voltage
Move from the continuous world to a digital value.
Open the lesson ↗04Years 12 → 13 · Digital sensorAcquire a temperature
Understand conversion and errors.
Open the lesson ↗05Year 13 · Synthesis projectThe connected beehive
Measure, process, communicate and validate.
Open the lesson ↗IN YEAR 12
Observe and explain.
Identify inputs and outputs, read a schematic, upload a program, record values and compare expected and measured results.
IN YEAR 13
Design and justify.
Define requirements, manage several tasks, handle an invalid measurement, characterise a prototype and discuss its energy impact.
Which board do you need?
The first four practical lessons use a UNO R4 Minima or UNO R4 WiFi. The beehive project uses the UNO R4 WiFi. The Minima has no built-in Wi-Fi. The RA4M1 runs the program; UNO R4 GPIOs operate at 5 V.
The examples use Arduino C++ : basic C syntax, with Arduino libraries and objects.
