Etch-a-Sketch Digital Display Kit with Arduino Uno
Master Precision Control and Graphics with the Arduino Uno Etch-a-Sketch Digital Drawing Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine drawing smooth continuous lines on a crisp color display using two precise rotary knobs—just like a classic Etch-a-Sketch, but reinvented with modern electronics. This kit lets you build a digital drawing board that responds instantly to your hand movements, culminating in a satisfying screen-clearing shake effect triggered by a button. Perfect for anyone exploring the intersection of art, user input, and embedded graphics.
What You'll Build
You'll assemble a handheld digital sketchpad powered by an Arduino Uno, capable of drawing in multiple colors on a vibrant 2.4-inch TFT screen. Each rotary encoder controls an axis, letting you create intricate line art with no latency. A dedicated button wipes the canvas with a playful shake animation, just like the original toy.
What You'll Learn
- Read and debounce rotary encoder signals for accurate real‑time position tracking
- Drive an ILI9341 TFT display with full graphics primitives and custom libraries
- Solder through‑hole components on a prototyping board to build a durable permanent circuit
- Program Arduino to handle multiple non‑blocking inputs and trigger animation sequences

Who This Kit Is For
This kit is designed for electronics engineering students, particularly those in B.Tech ECE/EEE programs, preparing for Smart India Hackathon projects or final-year display assignments. It's equally suited for makers in ATL Tinkering Labs exploring advanced Arduino graphics and hobbyists who want a durable, self-contained drawing instrument with soldering practice built in.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Use the AI companion via WhatsApp or scan the QR code on the box. It gives step‑by‑step help specific to this kit, and our human team will step in if needed.
Do I need prior soldering experience?
Some basic soldering is helpful, but the kit includes a soldering iron and detailed instructions. Our AI companion also guides each joint, making this a great learning project.
Can I modify the display to show different drawing effects?
Yes, the code is fully open. You can add color palettes, brush sizes, or even a stamp tool by tweaking the graphics libraries—the AI companion can walk you through the changes.
What if the TFT screen doesn’t light up?
Check the backlight power lead and the Arduino voltage supply. If the issue persists, reach out via WhatsApp and we’ll replace any defective display promptly.
Two rotary encoders move X and Y axes on TFT to draw. Button clears screen with shake shake effect.
