What is a Color Code?
A Color Code is a short sequence of 2 to 4 colors that
Ozobot Evo can read and responds to. Evo uses optical
sensors and respond with pre-programmed behaviors–by
speeding up, slowing down, changing direction, or making
cool moves (see Color Code chart).
Ozobot Evo's Optical Sensors
Evo's optical sensors can read a range of colors and line
widths, enabling the bot to perform different movements.
Getting Started
It is important to calibrate your Evo before each session
and/or when you change surfaces. Calibration helps
improve code and line reading accuracy.
Evo will calibrate on a black circle (about the size of the
robot's base). When drawing, you can create your own
black circle with markers.
PSST! Helpful Hint:
Print out the 5x5mm graph paper
on the last page for practice!
RGB: 73/183/73
RGB: 17/131/198
CMYK: 72/0/100/0
CMYK: 82/40/0/0
HEX #49B749
HEX #1183C6
Front sensors detect
lines to follow
Middle sensor detects colors
How to Calibrate
Step 1:
Draw a black circle, slightly
bigger than your bot. Place
Evo on it.
RGB: 236/32/39
CMYK: 0/99/97/0
HEX #EC2027
Go
Button
Step 2:
Press and hold Evo's Go
Button for 2 seconds (or
until its top LED flashes
white), then release.

RGB: 0/0/0
CMYK: 30/30/30/100
HEX #000000
Step 3:
Evo will rotate left, right
move outside the circle, and
blink green when calibrated.
If Evo blinks red, start over
from Step 2 then release.
