Reading the Zumo 32U4 Proximity Sensors
There are three IR proximity sensors on the Zumo. All of them are on the lower sensor board that contains the downward facing light sensors. In addition to the sensors, there are four IR emitters. There are two front IR … Continue reading
Zumo 32U4 Drive to Edge
This post discusses a common issue with any sumo event or competition that involves navigating to a line. Our goal with this post is simply to drive the robot placed on a light colored surface until it reaches a dark … Continue reading
Zumo 32U4 Downward Light Sensors, Part 2 – Calibration
This post will discuss how to calibrate the downward facing light sensors, and to read the calibrated values. I went a little over the top on the calibration function, but it makes it that much nicer. You can certainly do … Continue reading
Reading the Zumo 32U4 Downward Facing Light Sensors, Part 1
The Zumo 32U4 has 5 downward facing light sensors on the front light sensor array. The light sensor array board also has 3 IR sensors used for proximity sensors or IR receivers for remote control. However, two of the light … Continue reading
Zumo 32U4 Simple LCD Display Test
I realized that before we can work on reading the light sensors, we probably should cover an easy way to display the data. There are a couple of ways to display data on the Zumo. One, which we will cover … Continue reading
Zumo 32U4 Motor Encoders
In the previous post, we walked through how to turn the motors on for a specific amount of time. In this post, we will turn the motors on for a specific amount of encoder pulses. Like the EV3, encoders count … Continue reading
Zumo Simple Driving Program
These blog posts on the Zumo will start out very simple. This is assuming the reader has little to no Arduino experience. The goal of this post is simply to teach the reader how to write a program that will … Continue reading
Pololu Zumo 32U4
Last week, I got a Pololu Zumo 32U4. I am quite impressed with this little robot and Pololu did a heck of a job putting this guy together. I’m in the process of teaching a group of kids how to … Continue reading
Air Vortex Cannon
Air Vortex Cannon Instructions Jason and I made this a long time ago, but I’m updating my site and figured this would be a good first post. These instructions detail a homemade air vortex cannon. This is very similar to … Continue reading
