In this case, Codgers do not need to be either male or ancient! Coding for Codgers will be open to anyone (Codgettes?).
Your children and/or grandchildren at school are learning 'Coding' - ie how to write computer programs. This group, in Martlesham Heath, is for people who would like to try it themselves. No experience necessary - this is not going to be a serious training course, it's just for fun.
Five of us met for the first time on Friday 28th October 2016 in The Runway cafe at Martlesham Heath. Everyone had a good time - with coffee and cake.
The next meeting is on at 10:00 in The Runway.
If you are interested, please contact me (Ken@CodingForCodgers.co.uk) for further information.
This warning triangle shows the computer we first played with. It costs less than £10. The program controls the three lights and the pattern depends on the code you write.
It contains a PICAXE computer (see What is PICAXE for more information).
Where do we go after that?
This first example works out the possiblities for a single line One Line
Schoolchildren are being given these to play with and learn about programming - so we thought we would try. We now have the traffic lights controlled by a BBC Micro Bit.
Among other things, we've been working on programs to solve Sudoku puzzles. There is an intellectual challenge in solving Sudoku puzzles. The challenge here is firstly to work out how we would do it on paper, then write programs to automate the process.
Here's a selection of web pages which run our programs to solve the puzzles. As time goes by we will add new ones which should be able to solve the more difficult problems.
Now we are stuck! If you click puzzle X1 or X2 then click Solve, the program will get stuck and not find a solution.
Can you finish them by hand? If so, please let us know what you did - and more importantly why you did it.
If we know the method used, we can include that in the program and it should be able to solve the more difficult puzzles. As we can't solve them by hand, we don' know what next to put in the program.
We can make a guess and find the solution, but that counts as cheating. Sudoku puzzles should all be solved by logic - with no guessing
Have a look at our latest program s109.htm. Click on any of the buttons from "Puzzle 1" downwards to see a puzzle - which will have all the potential values in the empty squares. Click "Solve" and the puzzle will be solved.
Try X1 or X2 and you will find that "Solve" gets so far, then gets stuck. In X1, you can guess at "5" for the bottom right "25". Change it, then click "Solve" again - the puzzle will be completed.
The challenge is to find the solution without guessing. If you can do that, and explain how you did it, then we can build your new rules into the program and it should be able to solve other puzzles.
REWARD Free coffee and cake for the first person with a solution!
We built a set of traffic lights - including a pedestrian crossing light
The lights are built out of Lego and yellow sticky tape. The computer is a PICAXE 18M2 ( a larger version of the computer for the Warning Triangle) and the program is written in PICAXE's very basic form of Basic
