Summer holiday fun

What a great summer holiday! Some new workshops and some traditional ones. We introduced 2 new ones which proved highly successful and we will be repeating later on.

The new ones were Morse code programming and Make a tune on a programmeable chip. It was great fun to see the children engage with music and explore different tones. As for Morse code, some great examples and children developed their Scratch skills which will help them in later life.

We are now working on some new ones for half term and after Christmas as well.

On Minster FM talking about coding

Got a text when in Tesco. A mum had seen my advert in Shine and could she book her son on some workshops. Oh, and she works at Minster FM and would I like to do an interview with her about what I do?

So my son and I turned up at the Minster FM studios to be met by Victoria Charles who does the morning show on Minster FM. We had a quick tour round – and had to be very quiet as we were in the studio next to the presenter as he was talking live.

Then the interview – great questions and a fun, interested presenter. The last time I was in the radio was when I was 10!!

The interview is here. I need to work on the video.

A Happy New Year to you all

So it’s the start of 2014 and the start of ScratchMyPi. It’s exciting starting a new business and I am sure this will be successful. I wrote my first computer program when I was 12 using a VIC 20 and Basic.

Computing in the old days

Computing in the old days

It was fun to use but what was hard was getting the computer grammar right. Put the wrong text in or miss a colon and you would get a syntax error.

 

But it taught the basis of computer programming. Thinking about what would happen and developing a sequence to make it happen.

That was a long time ago. Now we have much more user friendly programs like Scratch.  I first started using Scratch about 8 years ago and was impressed by how easy and obvious it was to use. But don’t be deceived. Scratch is very powerful and you can make fantastic things happen. All you need is a flow chart and patience to debug programs.

Linking Scratch to a microcontroller takes the power of Scratch a whole lot further.   A microcontroller is simply a chip with inputs and outputs.

Arduino microcontroller

An Arduino microcontroller. Each pin can control and input or and output.

A program can sense inputs from sensors. If you can think of a sensor, we probably have it.

Sensors include temperature, noise, light, water level, touch and heat.

The Arduino is able to recognise the strength of the “sense” – and gives you a reading.

What you do with that reading is up to you. With a number (variable) in Scratch, a lot can happen. Colours can change, objects can move. They simply respond to the variable.

You can link the sensor to an output. As the temperature gets warmer, a LED gets brighter. Or a motor spins faster. You can control the outputs from Scratch. Simply select a variable and the output alters.

It’s really exciting getting to do this with primary children. I don’t think there’s another company using Arduinos and the Pi as control devices in a primary school. The technology is simple to program – it just needs careful setting up which is my main priority. I believe that things need to be simple and reliable to ensure that children feel successful.

So we start the New Year and I am sure we will have plenty of bookings, I’ll put examples of children’s work and projects on here.
