OLED Radar Sweep Scanner Kit with Arduino Uno + Ultrasonic
OLED Radar Sweep Scanner Kit — Arduino Uno Polar Plot Radar That Turns Ultrasonic Data into a Live Display
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 a radar screen right on your desk—a sweeping line, glowing blips, and distance arcs appearing in real time as a sensor scans the room. This kit brings that classic radar aesthetic to life using an Arduino Uno, a HC-SR04 ultrasonic module, a micro servo, and a crisp 0.96-inch OLED display. Instead of a simple distance readout, you’ll build a polar plot that maps object positions within a 180° sweep, turning raw sensor data into a visualization that feels straight out of a sci-fi console.
What You'll Build
You’ll assemble and program a radar sweep scanner that continuously rotates the HC-SR04 sensor via an SG90 servo. The OLED screen draws a dynamic radar-style graph: a rotating beam, distance rings, and persistent blips that mark detected objects. Every sweep updates the display instantly, giving you a live view of obstacles, walls, or moving targets in front of the sensor.
What You'll Learn
- Interface an ultrasonic sensor and servo motor with Arduino simultaneously
- Program a polar coordinate system and convert distance/angle data into screen pixels
- Render real-time visuals on an I2C OLED display using buffer drawing techniques
- Manage multiple hardware modules without timing conflicts through non-blocking code

Who This Kit Is For
This intermediate kit suits CBSE Class 11-12 students working on physics or computer science investigatory projects that demand real-time data visualization. B.Tech ECE and EEE undergraduates can use it to demonstrate sensor fusion and embedded graphics for mini projects or hackathons like Smart India Hackathon. ATL Tinkering Lab mentors will find it a perfect hands-on module to teach polar coordinates, serial communication, and display programming.
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 for the AI assistant trained on this radar sweep project. It provides step-by-step debugging help, and you can also send photos or queries via WhatsApp for human support.
Can I export the radar data to a computer for analysis?
Absolutely. The Arduino Uno communicates over USB serial. Our code uses the same pins so you can send distance and angle values directly to a PC. A simple Python script (included in the AI companion) can log data and even recreate the polar plot on a larger screen.
What kind of range and accuracy can I expect from the HC-SR04 ultrasonic sensor?
The HC-SR04 reliably detects objects from 2 cm to about 4 meters. Accuracy is ±3 mm in ideal conditions, but soft fabrics or angled surfaces may reduce range. The radar sweep will plot blips proportional to detected distance, clearly showing walls and solid obstacles.
Can I power the radar from a USB power bank instead of the 9V battery?
Yes, you can power the Arduino Uno through its USB port using any standard 5V power bank or phone charger. The servo and OLED will operate normally. This is actually preferred for long-duration demonstrations or data logging sessions.
HC-SR04 on servo sweeps 180 degrees. OLED shows radar-style polar plot with distance arcs and blips.
