Fly Eye Compound Lens Analyser Kit with Arduino Mega
Fly Eye Compound Lens Analyser Kit with Arduino Mega – Map Light Direction Like an Insect Eye
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit lets you construct an 8‑channel light direction sensor array that captures illumination intensity from different angles simultaneously, exactly as a fly’s compound eye does. By arranging eight BH1750 ambient light sensors in a hemispherical pattern and reading them through a TCA9548A I2C multiplexer, you’ll generate a real‑time sensitivity map. The data is timestamped with a DS3231 RTC, displayed on a 1.8‑inch TFT, and logged to a microSD card. It’s an ideal foundation for bio‑inspired vision research, smart lighting control, or an advanced engineering capstone project.
What You'll Build
You’ll create a self‑contained instrument that scans eight independent light channels up to 200 times per second and plots the directional intensity profile. The TFT screen shows live lux readings per sensor and a simple compass‑like indication of the brightest source. All records are saved to microSD with precise timestamps, so you can later analyse how the pattern shifts as light sources move. The final assembly sits on a dual prototype board and runs from a 9V battery, making it portable for field tests or classroom demonstrations.
What You'll Learn
- Multiplexing up to eight I2C devices with the TCA9548A and managing address conflicts on Arduino Mega
- Calibrating multiple BH1750 sensors for uniform response and compensating for orientation offsets
- Integrating a DS3231 real‑time clock and microSD module to build a timestamped data logger
- Interpreting directional light intensity patterns and relating them to compound‑eye principles used in biomimetic engineering

Who This Kit Is For
This advanced kit is built for B.Tech ECE/EEE students developing a final‑year project on bio‑inspired sensors or autonomous light tracking. It’s equally relevant for Smart India Hackathon teams needing a rapid directional sensing prototype, and for research scholars at IIT, NIT, VIT, or BITS exploring insect‑vision algorithms. CBSE Class 12 students with strong Arduino experience can also use it for science exhibitions or ATL tinkering lab extensions.
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 launch the AI build companion; it walks you through each step and even troubleshoots connections. You can also message us on WhatsApp for a real‑time response from our support team.
Can I increase the number of sensor channels beyond eight?
Yes, the TCA9548A multiplexer can address up to eight I2C buses. By cascading multiple multiplexers, you can expand the array to 64 or more BH1750 sensors with minor code changes.
How is the light direction actually determined from the sensor readings?
By comparing the instantaneous lux values from the eight sensors, the Arduino identifies which channel shows the highest intensity and interpolates the direction using its known orientation. The TFT then displays the dominant angle, and logged data lets you plot full polar sensitivity profiles.
Does the kit require soldering?
Yes, the prototyping boards, sensor headers, and display connections need to be soldered. The kit includes a soldering iron and lead‑free solder wire, and the AI companion includes a soldering guide specific to this project.
Multiple BH1750 sensors in a compound lens array measure light direction sensitivity pattern.
