Learning to code doesn't have to mean locking yourself away for months with a Python textbook.
These days almost anyone can learn to code and build computer programmes (including their own games). All you need is some imagination, some patience and some gadgets. We can only really help you with the last one.
Here, as a gift to all our loyal readers (and those that got here by accident), are a couple of hands-on projects to get you started...
Build it: DIY gamer kit
■ So you dug out your old Nokia 3210 to play a nostalgic game of Snake but there’s less life in it than a Tory MP’s 60th birthday party. Don’t worry. TWSU’s DIY Gamer Kit has all the ingredients you need to make your own handheld console, with Snake pre-coded for you.
■ Sounds too easy, right? Depending on your skill level you can buy it pre-soldered, or for £10 less do all that yourself. There are 40 pieces that need to be assembled on the circuit board, including an 8x8 display and four-way D-pad. It should take about 90 minutes.
■ After about five minutes, when you’ve remembered how tedious Snake is, download the Arduino Game Library from the TWSU website and you’ll be able to install others, such as Breakout and Flappy Bird. It’ll also allow you to tinker with the games’ source code.
■ Once you have the Arduino software you can also start writing your own games for it. There’s a whole section on the TWSU website with tips, guides and cheat sheets to help. Don’t expect Far Cry 4 – it’s only an 8x8 screen – but it’s a good way of picking up the basics.
Project #1 (easy): learn a programming language
Learn a new languageUsing a Raspberry Pi Model B, the Kano kit is designed to teach the basics of coding using its own Blocks programming language. It comes with a keyboard (including a touchpad), case, speaker, Wi-Fi dongle and its Kano OS pre-installed on an 8GB SD card. You just need to add a monitor or TV screen.
Time to swot upIt also comes with a manual – and you might just have to read this one. Everything slots together neatly and it’ll gradually introduce you to the different principles of coding. After typing a few commands you can dive right into Pong and start messing about with the size and speed of the ball.
Give it a PiKano isn’t just a tool to teach coding. Don’t forget there’s a Raspberry Pi under there, so it can access the internet, stream video, run a home server, or do any of the projects posted online, including a fart detector, Wiimote-controlled robot butler, and a time-lapse camera housed in an old coffee tin.
Project #2 (hard): build the button of power
Arduino is like the gadget-making equivalent of Raspberry Pi: while the famous tiny-puter is ideal for creating code, Arduino is an amazingly powerful way to get into building your own gadgets.
On Decoded’s Future Tech In A Day course (decoded.com), Stuff was shown how to make a live Twitter sentiment-o-meter; an entry-level project, yes, but you have to take baby steps before you can build a fire-breathing animatronic pony. Here, an adapted design from Instructables.com by bigbuttonfun.com will create a button that can perform any task that can be automated by web service IFTTT. The button sends an email to your Gmail account, and when IFTTT sees, it can do whatever you want it to: tweet, text, switch all your lights off or heating on, and much more besides. Truly, a Button of Power.
Step 1 - Create the trigger emailVisit futuretech.decoded.com and create a unique Arduino identity by clicking the button. On the ‘Configure your Tech in a Day’ page, under ‘Add a new Trigger’, select ‘Send an Email’, give the trigger a name, then enter the Gmail inbox you want to send an email to, and a message if you so wish. Click ‘Add the trigger’.
Step 2 - Write the codeDownload the Arduino software from arduino.cc and create a new sketch from the file menu. Copy the code at this page into the sketch, adapting with your own Ethernet Shield’s MAC address where appropriate (it’s on a sticker on the box) and ensuring your Arduino’s unique identity is referenced. Step-by-step instructions are available at futuretech.decoded.com/api/
Step 3 - Build your button1 x Arduino Uno (£25 (RM140))1 x Arduino Ethernet Shield (£30 (RM170))1 x AD101 breadboard (£3.60 (RM20))1 x 105T switch (RM9)10KOhm resistor (a few ringgit)4 x jump wires (RM12)1 x USB wall plug1 x Ethernet cablePlace the Ethernet Shield on top of the Arduino Uno, making sure the pins line up, and push them together. Assemble components as shown in the photo. Connect to your computer via USB and upload the sketch, then hook up to your router via Ethernet. Now, pressing the button on the breadboard will send the email. Now use the USB wall plug.
Step 4 - Create your IFTTT recipeNow you can formulate recipes on IFTTT.com for when an email lands in your account. Building recipes is simple; so get thinking.
