Welcome to my instructable!

The project I want to share with you today is Arduino Color Picker, a device that will let you pick any color from real life object(s) and display it in convenient way so you can use it for example in any drawing software, GUI web development and much more!

Step 1: Parts List

Picture of Parts List

For this project we will need:


  • 3D printer, if you don't own it, you can get printed case from Shapeways: click here
  • phillips screwdriver
  • soldering iron
  • solder

I have been trying to make this but I'm afraid it is simply not possible with your code. Something about the dfrobot vs the more readily available components. dfrobot is not sold in the states and ordering from their website makes everything about 3 times more expensive. I tried to do it with components readily available in the states unfortunately my coding experience is very limited and I'm struggling to make it do literally anything. Do you have any suggestions. I have never had so much trouble building anything off of instructables in my life. I have the tcs34725 but the get data command is different I know this is part of my problem. I have adapted your original designs to use 3.7 volt rechargeable battery as well but that should have no real effect on the coding. I don't see anywhere in your code that you assign addresses for the 2 I2C devices (necessary since I am going to replace the LCD with a ssd1306 OLED which makes more room for the battery and consumes less power plus the contrast makes it easier to read. Is there any advice you can give me. I'm struggling to get any output using your code even to a simple i2c lcd.

Great idea! The commercial versions are insanely expensive and this looks really professional. :)
