ELEGOO UNO R3 Basic Starter Kit: every lesson, simulated

The eleven lessons of the kit’s tutorial, in its order, each one a circuit you can run in your browser with the kit’s parts on the kit’s pins. Start with a blinking LED and finish with a light meter on eight LEDs.

Lesson by lesson

Every lesson in the kit’s order

Lesson numbers and titles follow the English tutorial V1.0.19.7.24, from the download dated 2019.09.16. Each circuit uses the kit’s parts on the pins the lesson uses.

10 of the 10 lessons with a circuit run here, 1 setup lesson needs no circuit.

0
Installing IDE
No circuit
Installing the Arduino IDE. Nothing to install here: the editor and the compiler run in the browser.
1
Add Libraries and Open Serial Monitor
Runs here
Printing from the board to the serial monitor. The libraries the lessons use are already built in.
Open the guided lesson
2
Blink
Runs here
The board’s own LED on pin 13: on for half a second, off for half a second.
Open in the editor Arduino Uno blink
3
LED
Runs here
An LED and a 220 ohm resistor straight from the 5 V pin, no code. Swap in the 1k or the 10k and watch it dim.
Open in the editor An LED on the 5 V pin
4
RGB LED
Runs here
An RGB LED with red on pin 6, green on 5 and blue on 3, fading from one color into the next with analogWrite.
Open in the editor RGB fade on pins 6, 5 and 3
5
Digital Inputs
Runs here
Two push switches on the internal pull-ups: the one on pin 9 turns the LED on pin 5 on, the one on pin 8 turns it off.
Open in the editor Two buttons, one LED
6
Active buzzer
Runs here
An active buzzer on pin 12 sounds while the pin is HIGH: a run of quick beeps, then slower ones.
Open in the editor Active buzzer
7
Tilt Ball Switch
Runs here
A tilt ball switch on pin 2 with the pull-up on. Tip it over and the LED on pin 13 lights.
Open in the editor Tilt switch
8
Eight LED with 74HC595
Runs here
Eight LEDs from three pins through a 74HC595 shift register: data on 12, clock on 9, latch on 11.
Open in the editor Eight LEDs on a 74HC595 (pins 12, 9 and 11)
9
The Serial Monitor
Runs here
Type a number from 0 to 7 into the serial monitor to light that LED on the shift register, or x to clear them.
Open in the editor Serial monitor drives eight LEDs (74HC595)
10
Photocell
Runs here
A photocell on A0 decides how many of the eight LEDs light: more light, longer bar.
Open in the editor Photocell bar graph on a 74HC595

FAQ

Questions about this page

Is this made by ELEGOO?

No. Mokxi is independent and is not affiliated with ELEGOO. The page follows the kit’s lessons so you can use the two side by side; the circuits, sketches and explanations are Mokxi’s own.

Do I need the kit?

No. Every lesson that runs here runs in the browser, so you can try them before you buy a kit, or keep going while a part is missing or broken.

Is the code the same as in my manual?

The pins and the parts are the same, and the sketches use the same libraries where the kit does. The code itself is written for this page, with comments that explain each step, so it will not match the manual line for line.

What do "with a change" and "coming soon" mean?

A lesson marked "with a change" runs, but something differs from the kit, and the note under it says exactly what. "Coming soon" means we cannot simulate that lesson yet, and the note says why. We do not mark a lesson as running unless it does.

Is it free?

Yes. Every lesson on this page opens with no account. A free account saves your own copies of the circuits.
