Each one is in the editor’s parts panel. - Arduino Uno Rev 3 Board Arduino Uno R3 - Breadboard & Breadboard Holder Full-size breadboard The holder has nothing to place. - Red LEDs and Yellow LEDs LED - RGB LED RGB LED - 350 Ohm Resistors and 10 kOhm Resistors Resistor - 10K Potentiometer Potentiometer - 12mm Buttons Pushbutton - Piezo Buzzer Piezo speaker - TMP36 Temperature Sensor Temperature sensor - Servo Hobby servo - DC Motor DC motor - 5-Volt Relay DPDT relay - Shift Register 74HC595 shift register Vilros does not name the chip on the page; the 74HC595 is the common eight-output shift register. - P2N2222A Transistors Transistor (NPN or PNP) Set to 2N2222, the same transistor. - 1N4148 Diodes Diode - Instruction Manual The printed 72-page manual; nothing to place. - USB Cable The editor connects the board for you. - Jumper Wires Drawn as wires between pins; nothing to place. Parts list read from Vilros’s product page. An item with no part beside it has no match in the editor yet. For the manual ## A link and a QR code for this page Print either one beside a lesson, or tape it inside the box lid. Both open this page. mokxi.com/k/vilros-arduino-uno-ultimate-starter The code is black on white with a quiet border, so it prints and scans at any size from 2 cm up.

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.
