Welcome to my channel! My name is Ethan, and I teach robotics!
My tutorials and videos relate to the LEGO Mindstorms EV3 platform, teaching programming skills, engineering principles, and tips for the FLL (First LEGO League) competition. Through my videos, I hope I can inspire and help youth in their pursuit of STEM fields.

FLL Must-Haves: Drive Straight using Motor Encoders!
We usually drive straight with a move tank or move steering block. However, factors such as motor drift can cause our robot to drive off course. By using the motors built-in sensors, or motor encoders, we can ensure our 2 motors move the same speed and distance.
This lesson also teaches you how to compress a longer, more complicated program into a MyBlock, as well as applying techniques from other videos to streamline your code!

FLL Must-Haves: File Save for AutoCalibrate!
มุมมอง 2744 ปีที่แล้ว
Writing an automatic calibrate saves our highest and lowest values to variables, which can be deleted and is only saved in our project. Saving it to a file save location allows the values to stay consistent, and also gives us more control within all programs and projects! When your robot has multiple uses, in competitions, home use, or even education, this lesson has both practical and educatio...
FLL Must-Haves: Automatic Calibrate!
มุมมอง 2934 ปีที่แล้ว
This automatic calibrate requires just a single button press from the operator! Extremely useful for competitions such as FLL, by cutting down time required to calibrate, and also removing any human error from the process. In addition, this calibrate can be used universally, across any lighting conditions or surfaces, and come back with the 2 most important values. The robot, while running over...
Display Screen for Calibrate: FLL Must-Haves
มุมมอง 1394 ปีที่แล้ว
We take the calibrate made in the last video and add a screen to it! In this video, I expand on the simple calibrate by making it easier to operate and run. The display shows instructions for how to use the calibrate, as well as shows the RLI (reflected light intensity) for black and white. This way, we no longer have to check on the computer if the calibrate worked. Like and Subscribe for more...
Simple and Easy Calibrate for EV3: FLL must-haves
มุมมอง 2834 ปีที่แล้ว
Write a calibrate program that teaches the robot the reflected light intensity of white and black. In this video, I teach you the most basic and simple way to write a calibrate, with manual input by the operator. These values can be used in any program, and if used properly, can be used in any lighting condition. A calibrate allows us to take our robot to any location and have it run smoothly! ...
Simple and Easy Line Follow for EV3: FLL must-haves
มุมมอง 2914 ปีที่แล้ว
Black and white lines are found everywhere in robotics, and are extremely important for the robot to re-adjust and more importantly, follow. Learn how to write a simple and quick line follow for any scenario! Using Loops, Switches, and a few move blocks, you can improve the consistency of your robot by a huge amount. Like and Subscribe for more videos just like this! Watch my loops and switches...
EV3 programming 8: File access, easy and versatile saving!
มุมมอง 1.1K4 ปีที่แล้ว
Learn how to use the file access block in our code! File access blocks helps us save numbers and text to our computer or the cloud instead of just in our project. This means that we can use the value in any program we want. In addition, file access blocks save into a document that has an infinite amount of space, making saving large amounts of information extremely easy.
EV3 programming 7: Creating custom blocks using MyBlocks!
มุมมอง 1.1K4 ปีที่แล้ว
In this video, I will be teaching you how to use MyBlocks to your advantage by creating, viewing, editing, and adding parameters to them. Programs in EV3 are long and complicated, and copying over certain areas of code can be TIRING. With Myblocks, you can set up a program in a matter of seconds, and save sections of code to reuse for later. It also streamlines your program and makes it easier ...
EV3 programming 6: Array Blocks and Array Operations
มุมมอง 1.9K4 ปีที่แล้ว
Array blocks store data in a compact, organized way at the cost of complexity. In this video, I teach you the concepts and basics of array blocks! Included is how you can set up arrays, read a specific number at an index, add a number at an index, and check if everything is running smoothly.
EV3 programming 5: Math Blocks and Constants!
มุมมอง 8994 ปีที่แล้ว
We continue with data operations blocks in the 5th episode of my EV3 programming series! In this video, I cover the basic concepts and applications of math blocks to add, subtract, multiply, and divide, as well as constant blocks and their differences from variables. These blocks will later be used for more complicated programs such as calibrates, drive straight programs, and more!
EV3 programming: Using Variables with sensors to save values and calibrate your robot!
มุมมอง 1.9K4 ปีที่แล้ว
In episode 4 of my EV3 programming series, I show you how to apply colour sensor values in switches, loops, and most importantly, variables! Using the advanced variable block, values can be saved throughout your program and can be plugged in wherever necessary. In this lesson, program a simple calibrate program that allows you to set values for colour sensor thresholds just by holding the robot...
EV3 programming: Using the color sensor to achieve autonomous control over your robot!
มุมมอง 9054 ปีที่แล้ว
In episode 3 of my EV3 programming series, I teach you how to use the color sensor to detect a black line, explain reflected light intensity (RLI), how the color sensor works, and how to attach it to our robot! By integrating the color sensor into our programs, we can control our robot just by it driving over a colored line, which triggers a command. Instructions to attach color sensor (also sh...

omg thanks dude u saved me fr can I get your insta plz?
Thx for uploading this video!
thanks for the info but a little clarification on variables
hi do u have this in ev3 classroom code
Thank you so much!
amazing explanation
Great Video. I like the way how you narrate the contents and video. As I'm not able to connect to you, wonder whether you are interested to help assist on video making of mindstorm with contents I've prepared with some minimal fees. let me know if you are interested and email me at mobilenews.mal@gmail.com
Looks very similar to mine. Great minds. If you are going to just use high and low I would also recommend normalising or mapping the values for use. Equation for mapping: mappedValue=(currentValue-min)/(max-min)*100. This will keep your Min and Max in 0 to 100 scale as you technically haven't calibrated with you code.
Really great videos, I have learned a lot from your channel. Keep it up, and look forward for more and more videos to come! Bravo!!!
EXCELLENTTTTTT!!!
Love the enthusiasm!
Great Video! Excited for the next one!
No way bro I was looking for this video for 40 years, finally someone smart enough to post this holy

Thank you so much for the great information!!! This will really help me complete my math homework. Love from Wakanda.
Wakanda forever
OMG ROBOTICS4U I AM YOUR BIGGEST FAN. I have seen all two of your videos!!! Love from Antarctica!!!
Very good job, young man . Pretty impressed, keep it up and looking forward to more videos to come.
Excellent video! LOVE to see more!
I live in Nebraska and am an aspiring engineer. I struggle to understand the concepts of robotics but this video was extremely helpful and informative. You just earned yourself a subscriber!!
