In this tutorial I show how to put together the Communications station and then how to program your robot to complete the first mission. If you have just bought the EV3 Mars space challenge and have no idea how to complete any of the missions, this is the tutorial for you. When I first got …
In this final lesson on Lego EV3 we’re going to use everything we’ve learned to build a reaction time tester. You’ll also learn about Timers, which is used to measure how much time has gone past. Basically the program will play a sound at a random time, and you will need to press a button …
In this tutorial, we learn how to save the reading obtained from an ultrasonic sensor to a text file ONLY when the user presses a button.
In this tutorial we talk about how to display dynamic content on the screen. We’re going to set up a voting booth so that when a button is pressed, the number stored in a variable increases by one, and the number is updated on the screen, and when another button is pressed, another number updates …
In this lesson we show you how to write a program to display some text on the brick’s screen and wait for the user to press a button on the brick to end the program.
In this lesson we talk about how to use the data logging block in the programming interface so you can program your robot to do other things (e.g. moving around) as it is logging data.
In this lesson you learn how to use lego to record some ultrasonic sensor readings over a time period e.g. 15 seconds by using the experiment feature of the EV3 software. You then learn how to export this data to a CSV spreadsheet file which can then be opened in Microsoft Excel to do some …
In this lesson we create a robot that randomly roams around the room and avoids obstacles using the ultrasonic sensor. We also cover the concepts below: – What is a variable and how to use it – How to interrupt / resume a loop – How to have multiple programs running (multiple start blocks)
In this lesson we learn how to make the robot roam randomly around the room, by generating a random number between -100 and 100 and assigning this number to the steering property in the Move steering block.
In this video I talk about how to place a switch block inside another switch block, so you can utilise two sensors together. I show you how to program a car that follows a line AND stops to make a horn noise whenever an object is blocking its path.
