"Resist", The Resistance Checker
What is Resist
Do you hate having to figure out the resistance of a resistor by using a multimeter or calculating it with a color chart?
Resist makes it simple. With just one photo of a resistor, you can instantly find out its resistance value. Do not want to use the camera? You can also upload an image from your device.
Resist is a clean web app that detects resistor color bands from a photo and computes the resistance value. It is built with Flask, OpenCV, and a modern HTML, CSS, and JavaScript interface.
Displays the formatted value (Ω, kΩ, MΩ, GΩ) along with the detected bands
Two modes:
- Image Mode: Upload or capture a resistor photo and press Analyze
- Manual Mode: Select band colors and multiplier to calculate resistance without an image
Responsive UI for both mobile and desktop
Notes and Tips
- Good lighting and focus improve accuracy of band detection.
- Color thresholds for detection are defined in
resit.pyinColour_Range. You can adjust these for your camera and lighting. - Supported image formats:
.jpg,.jpeg,.png,.webp.
