Lets make a speedometer

This is our very first project and no matter where you are in the school you want to make sure you work through it and understand the concepts presented. These things will follow you along to a lot of other projects and we want to make sure that no matter your age you grasp what is here. So do NOT skip this lesson.

Step One

In this quick lesson we’re going to establish a couple of rules that we have to apply in all of our math problems from this point on. Follow along in this quick tutorial to establish those 2 easy to remember rules.

Step Two

In this video we dive into Python, the programming language that we’ll be using throughout this course. We won’t get into much detail in this video but I wanted to give you a very quick intro and explain what functions are.

Step Three

In this video we take a look at the microbit controller we’ll be using in our first project and how to make it do some basic things. We’ll be quickly moving onto using sensors with the card so this is just a quick overview of some of the basics before we get started.

Step Four

In this video we take a look at a very basic electric circuit so that we can better understand what is going on when we connect a battery.

Step Five

In this video we go a step farther and look at a specific switch circuit we’re going to be using in our next project.

Step 6

In this video we show you some ways to get help with the documentation on the microbit along with a few things about the hardware itself.

Step 7

In this video we dive into a bit more detail on the microbit controller as well as the use of the keyestudio adapter card.

Step 8

Lets take a quick look at what a multimeter is and how you can use it to find the secrets in almost any circuit board.

Step 9

This video takes us through wiring up our first ever electronic circuit and shows the python program we wrote to make it work.

Step 10

In this video we take a look at the math involved in our first project and how to calculate the speed and distance of Jacob’s bicycle so that we can eventually write a program to figure it out.

Step 11

In this video we take a look at using the Raspberry Pi to complete our speedometer project and how we might do that. We take a look at the GPIO pins (General Purpose Input/Output) to plug in our switch and then write some quick python code to work with it.

Step 12

What would happen if you didn’t have me here to help you along the way? Could you figure this stuff out on your own? I say yes!
