Arduino Oscilloscope Probe Calibrator Kit - 1kHz 3.3V Square Wave Generator
Arduino Oscilloscope Probe Calibrator Kit - Build a Precise 1kHz Square Wave Generator
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 your Arduino Uno into a professional-grade tool. This kit teaches you to generate a rock-solid 1kHz 3.3V square wave-exactly what's needed to compensate oscilloscope probes for accurate waveform analysis. Whether you're a young hobbyist setting up your first electronics workbench or a STEM educator demonstrating signal integrity, this build pays for itself the first time you trust your scope measurements.
What You'll Build
You'll assemble a dedicated signal generator that displays the output frequency on a 16x2 LCD via I2C. Two LEDs blink with the square wave, giving you instant visual confirmation. Plug your oscilloscope probe onto the breadboard test point, adjust its compensation screw, and watch the square-edge flatten into a perfect waveform. From unboxing to calibrated scope in one afternoon.
What You'll Learn
- Generate precise digital signals using Arduino's tone() and digitalWrite commands
- Interface an I2C LCD backpack to display real-time frequency readings
- Understand square wave characteristics: rise time, overshoot, and probe compensation theory
- Assemble a permanent calibration fixture on a breadboard for repeated bench use

Who This Kit Is For
Perfect for CBSE Class 11-12 students exploring waveform analysis in physics practicals, and for B.Tech ECE/EEE undergraduates setting up their hostel-room electronics bench. ATL Tinkering Lab instructors use this kit to demonstrate signal generation without expensive function generators. Young hobbyists aged 10+ can follow the pictorial booklet independently, building confidence with Arduino and breadboarding.
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 to chat with our AI companion that knows every wire and code line for this calibrator. It guides you through debugging, from LCD contrast to timing loops. Alternatively, WhatsApp us for direct engineer support within 24 hours.
Can I use this kit to calibrate any oscilloscope probe?
Yes. The 1kHz 3.3V square wave matches the standard compensation signal required by most passive probes (1x/10x). Whether your scope is a basic DSO138 or a four-channel Rigol, the clean rising edge helps you adjust the probe's capacitor until the waveform is flat and distortion-free.
Is this kit safe for a 10-year-old to build alone?
Absolutely. The build uses a 9V battery (not included) and low-voltage signals. There's no soldering-all connections are on a breadboard. With the AI companion's visual steps, a 10-year-old can complete it in a parent-supervised afternoon.
Can I reprogram the Arduino for other projects later?
Yes. The Arduino Uno is fully reprogrammable. Once you've used the calibrator, you can upload any sketch-turn it into a temperature monitor, a game, or the brain of your next robot. The kit components are reusable building blocks.
