Progress Bar Loading Indicator Kit with Arduino Uno + LED
Progress Bar Loading Indicator Kit: Visualize Data on Arduino OLED in 1-2 Hours
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn a potentiometer knob and watch a smooth progress bar fill the OLED screen—from 0% to 100% with every twist. This kit combines hardware and code to create a loading indicator that teaches real-time data visualization in a tangible, immediately satisfying way. It’s the first step toward building dashboards, battery meters, and UI elements on tiny displays.
What You'll Build
You’ll wire an Arduino Uno to a 0.96-inch OLED and a potentiometer on a breadboard, then upload code that draws a filled rectangle proportional to the knob’s position. A clear percentage label sits beside the bar, updating instantly as you rotate. The final result is a compact, portable progress indicator you can hold in your hand and demo to anyone.
What You'll Learn
- Drawing filled rectangles on an OLED using the U8g2 library with exact pixel coordinates
- Mapping analog input (0–1023) to percentage values (0–100) for smooth visual scaling
- Controlling graphical output in real time with a single analog sensor
- Assembling a clean, breadboard-based circuit without soldering or permanent connections

Who This Kit Is For
This beginner-friendly kit is ideal for CBSE Class 11-12 students exploring data visualization as part of their computer science or electronics curriculum, young innovators in ATL Tinkering Labs building their first Arduino project, and curious minds aged 5-15 who want to see code turn into a real display. B.Tech ECE and EEE students can use it as a warm-up before tackling Smart India Hackathon challenges.
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?
Scan the QR code on the box to open the AI companion trained on this kit; it guides you step-by-step. You can also reach us on WhatsApp or email for direct help.
What can I build after mastering this kit?
Once you can draw progress bars and map values, you can create battery indicators, audio volume displays, or sensor dashboards on the OLED—small building blocks of a full UI.
Is any soldering required?
No soldering at all. Every component plugs directly into the breadboard; the kit is completely solderless.
Can I power the kit from a USB port instead of the battery?
Absolutely. The Arduino Uno can be powered from its USB port while building and testing, but the included 9V battery snap lets you go portable after uploading the code.
Potentiometer controls progress bar fill on OLED. Teaches rectangle drawing and percentage mapping.
