## Description

![piicodev-colour-sensor-veml6040-lime](https://core-electronics.com.au/media/wysiwyg/tutorials/michael/piicodev-veml6040/piicodev-colour-sensor-veml6040-lime-small.jpg)Use the PiicoDev® Colour Sensor to measure the RGBW components of light, or even extract the colour of an object so you *can* compare apples with oranges. Onboard is a high accuracy colour sensor - the VEML6040 boasts 16-bit precision for each channel (R, G, B, W). By using PiicoDev adapters and cables, you can connect to this sensor without soldering - or use the standard breakout header if you prefer breadboard prototyping. Whichever you prefer, the PiicoDev [guides](https://core-electronics.com.au/guides/piicodev/) will get you measuring colour in no time!

**Features**

**PiicoDev Overview**

[PiicoDev](https://core-electronics.com.au/piicodev.html) is a [![](https://core-electronics.com.au/skin/frontend/white/default/images/ce_original_blue.png)](https://core-electronics.com.au/original) ecosystem designed for rapid prototyping and maker education. The range includes:

- [Starter Kits](https://core-electronics.com.au/piicodev.html#category_1322)
- [Sensors](https://core-electronics.com.au/piicodev.html#category_1380)
- [Outputs](https://core-electronics.com.au/piicodev.html#category_1381)
- [Adaptors & Expansion Boards](https://core-electronics.com.au/piicodev.html#category_1307)
- [Platforms](https://core-electronics.com.au/piicodev.html#category_1310)
- [Cables](https://core-electronics.com.au/piicodev.html#category_1309)
- [Accessories](https://core-electronics.com.au/piicodev.html#category_1323)
 
Here are some of the features we have baked into PiicoDev:

- **Unified MicroPython libraries.** The same MicroPython code examples will work on all supported platforms.
- **Simple-and-expandable connections.** Modules can be connected using a 4-pin connector and daisy-chained to expand projects.
- **Breakout pins.** Every module has a breakout section for optional advanced uses.
- **Consistent size.** We have taken care to ensure modules are consistent sizes so that they easy for 3D printing cases, stacking and experimenting with.
- **Creative freedom.** Simmer all of these features together and you end up with lots of creative freedom while still being a hands-on electronics experience.
 
PiicoDev modules are designed by our team in Newcastle and manufactured in Australia and overseas. They’re made for makers and educators alike — affordable, reliable, and easy to use. [Get in touch](https://core-electronics.com.au/contacts/) if you have any questions.
