Last Sunday Session 25th June

Just a reminder there be the final Sunday session this coming Sunday 25th June. We will celebrate the success of our winning Ninjas at CoolestProjects and another successful term CoderDojo Dun Laoghaire and hope that some of the Wednesday Ninjas will come to share in the fun.



WebSite Competition – CoderDojo Dun Laoghaire Sunday 04th March

This coming Sunday, after many weeks of hard work, we will see Liam, Jack, Ian, and Darrach present their projects in the hope of winning the coveted award of ‘Voted Best Website 2017’. This will be followed by an award ceremony and prize giving as well as an interview with the proud winner of the coveted CoderDojo Dun Laoghaire Web Design Trophy. An event not to be missed!

Rock Paper Scissors using the MicroBit

The Microbit is a fun little device, it allows you to program it in a variety of languages with a variety of different programming IDE’s.

The 20GBP device supports motion sensing (Titling, Shaking) and can display images on a 5×5 LED matrix. Microbits can be connected together over a radio link and share data and the device is small enough to be powered by two AAA batteries.

This project uses these capabilities to re-create a fun game – rock paper scissors using two MicroBits. I recommend using the Microsoft PXT IDE which lets you switch between Blocky and JavaScript and has the Radio add-in that this project needs…

1. Connect the two MicroBit’s wirelessly with the Radio library
2. Shake the device to make a selection
2. Randomly choose one of the three choices
3. Display the result on the LED
4. Send the result to the other Microbit
5. Work out which device won and display that to the user

How would you modify your program to make the game fun for the visually impaired?
Would it be fun to extend it to include Rock, Paper, Scissors, Lizard and Spock…

Making friends with your new assistant – Alexa

Some of you may have already met her or her friend Siri, they perform a similar function, they are good listeners and really want to help you with your problems. I am of course talking about Amazon’s AI tool which has started to be embedded in a number of devices – including Amazon’s own Echo device.

Here’s how it works:

1. You wake up Alexa – Amazon echo is listening for you to say Alexa – other devices need to have a button
2. You talk and the device records
3. The recording is forwarded to the Amazon AI
4. The AI decodes what you have said and determines an answer
5. The response is played back to you.

Well the good news is there’s a public API for developers and a some Python code out there to allow us to connect to it. There’s a small amount of wiring but not much! Try it out…

And when you have connected to it, now you can connect it back to you (eg using IFTTT)…
