The problem with the attention of students

We all know that it is very hard to control students’ attention even in an in-person classroom and it is even harder in a remote learning environment from home.
Now with remote learning, a teacher must be even more engaging, and the best teachers integrate more and more playful based learning so that students are interested and involved.
In this article, we will share how to achieve that, what are the best practices and benefits and how to convince your decision-makers to allow more play-based learning in your virtual and physical classrooms.

In this course, you will learn how to program the game "Keep 'em clean". This is a game where the player controls a number of "people" on the screen using movements detected by a camera.

The goal of this lesson is for students to have fun with a new robot. 

The goal of this lesson is to introduce students to the setting for measuring the reflected light of the color sensor and to recall how to follow a line.

Third wheel experiments, changes in the robot, students could choose the task all by themselves. Make sure you have a lot of fun and students complete their tasks. Here is what you should know when conducting this class.

Mission

The robot should park in the parking positioned in the north-east corner of the field.

Scores

At the end of the match the robot is completely in the parking area in the north-east corner of the field: 50 points.

There are two types of inertia to familiarize yourself with. One you know intuitively, while the other is more obscure. Both must be considered when building your own robots, especially in future competitions.

As the name indicates, ultrasonic sensors measure distance by using ultrasonic waves. One of the “eyes” on the sensor head is the transmitter and emits an ultrasonic wave and the other “eye” is the receiver which receives the wave reflected back from the target. 

A clutch is a mechanical device that is used for engaging or disengaging power transmission. Now we will see how we can make such a device using LEGO.

Your first task follows, and we will explain how to use tasks.

We are about to connect the whole car with the lights and motors to the controller. Let's recap to know what is ahead of us, what would the process be and what is the end result of the next couple of sections when at the end we have a car controlled by the phone

The power in the car comes from the batteries. The batteries are in a batteries holder. About 5 of them. Two cables are connected to the batteries holder. It is very important to identify which of those cables is the plus and which is the minus.

We would start connecting a lot of things to the Raspberry Pi. It will be good if we could have some way of referring to the pins on the Raspberry Pi. For example like Pin 5 or Pin 26. Luckily there is such a way. 

In the set for the Perfect Course, you have 3 different type of cables. They are called Breadboard Jumper Cables. We would need to use them to extend the default cables on the car and to connect the car components to our new controller

We need to extend the cables to be able to connect them to our Raspberry PI. We must also add new connectors at the end of the cables.

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? 

Give it a name and you will have power over it. I learned this from an MIT professor. So let's give the part of the car names. Then we could refer to them. Talk to them. Change them. Do all kinds of things with them. Give it a name and you will have power over it.

The course is designed to be used with almost every remote controlled car. The process of opening the car will be different for different cars but there are basic principles that you could follow.

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.

In the course, we are going to use the following components and hardware elements. It is important to know their names and what are they used for.

Let's attach the ball storing pipe to the FTC robot. In previous tutorials, I've shown you the complete robot, but for this, I've removed the pipe and will show you how to attach it.

Take the hacksaw, the drill and let's cut the pipe.
