Following the Advanced Sensor Calibration course section, it is time to extract the logic for getting a calibrated value into a new block. This block will have an input and on this input, we give the port number. The block will return the calibrated value for this port number. We've built all the other blocks only because of this almost final video here.

To correctly upload the blinking diode program to the controller we must first check some of the configurations of software. These are the "selected controller" and COM port

In this video tutorial, we demonstrate how to release the cargo of a mission model. This mission model is an Airplane. We have to push a lever down to release it. We use an active attachment with a gear wheel.

What should you do as a teacher when the students are calculating the gear ratios and number of needed rotations?

In this video lesson, we will show you how to build a menu as a MyBlock in LEGO Mindstorms NXG-G. Having a menu is a must at robotics competitions since it saves time and gives easy access to program functionalities.

This lesson shows how you could use the rotation sensors of the motors of a LEGO MINDSTORMS NXT robot. This technique is very powerful during the competition. We give ideas on how to show the value of the sensor on the display, how to check if you have completed a given job or you are still doing it and other even more advanced topics. Understanding the rotation sensor is a must if you want to use the full capabilities of the motors.

In this video tutorial we are demonstrating the impact of slow and fast acceleration on the robot. In the Scratch program there is an acceleration block for fast and slow acceleration. The robot behaves in different way. Let's explore them so that you know what to use for FIRST LEGO League competitions.

Every electronics tutorial, book or course about Raspberry Pi or Arduino will use a motor driver. Very few of the courses will actually explain why do you need a Motor Driver, what is it for? 

When you first start the EV3 brick, you see the recent programs menu. Let's see what it is all about.

In this episode of the Basic NXT Programming series I will cover the sound sensor. I will explain how to program the sound sensor, stop on common problems faced, when the sound sensor is used and finally we will build a program that will allow us to control the robot's speed through the volume of the sound.

This is a 10 out of 10 tutorial demonstrating the consistency and reliability of a LEGO Education SPIKE Prime robot when the robot delivers a mission model to a specific position on the field.

In this video tutorial we take a next step in programming reliable and consistent robots and this is to learn how to stop at a second intersection. We need this because most of the time when we want to reach a mission model on a robotics competition field, the model will be located away from us and we must use all kind of technique to reach it. In this tutorial - we stop at a second intersection.

One of the very common tasks on different FIRST Technical Challenge competitions is to collect objects. In this case, these are colourful specifically shaped plastic object or in simple terms - balls.

A special fourth case for a turning with robots with two wheels.

Now that we know how to make the robot move forward let's see we can make it move backward. 

One of the interesting things in this sequence of videos is the program. The program detects when the system has reached the maximum speed and then stops the motor from rotating. We detect this with the EV3-G software

Level 2 from "FLLCasts Certified VEX IQ Robot Driver - Class R1" certification path is to start on the border of the field, move through to the last obstacle, turn and return back to the first one. turn once again and go up to the second one, turn around one last time and sprint towards the finish line at the border of the field.

With the set for the course, you also have an SD card. It is important that you understand why and how is the SD Card is used. 

Yes, we know. Starting with the phone when you have a toy car and a Raspberry Pi might seem strange, but this is why we do it.

Unpacking the VEX EDR set and learning the names of the different parts included in the set

We use a sensor so the robot must be reliable and accurate right? Wrong. The robot is not reliable and accurate only because we use sensors and that's really important during FIRST LEGO League competition. There is a reason for this and in this tutorial we demonstrate and explain how the robot behaves with a basic use of the Motion Sensor to move straight. As a result you will learn why is it important not to stop at this stage and to go to the next level with more advance use of sensors.

In this tutorial, we show you how to display all the values from an EV3-G array on the EV3 brick display. We are using an array Read Operation along with a loop. We are also detecting the loop counter and using it as an index to an array. It's basically the only viable way to do it. The process is commonly referred to as - "Iteration over an array" (although we still do not have an iterator in the programming language, we promise that one day we would do the super advance videos on "iteration" using the LEGO MINDSTORMS robots")  

In the EV3-G software, you could use negative numbers for power and rotations. In this episode, we would look at what is the meaning of this numbers and make a few notes of where the teacher must be more careful.

In this video tutorial we accomplish the basketball mission from the FIRST LEGO League 2020 reply competition. We use the LEGO Education SPIKE Prime competition robot called Gazon. You will learn the principles of accomplishing a mission of two parts - put the ball in the basket and lift the basket.

This video tutorial shows how the LEGO Mindstorms EV3 Rider Robot Motorcycle with Cart robot works. You can ride a friend with you.
