Start Emulating an Apple I on Your TV Wirelessly with a $3 ESP8266: A Cool and Creative Hack



If this is your very first time programming or coding, we suggest starting with MakeCode - it is super fast to get started not just with Circuit Playground Express, but coding in general! (Once you've got the hang of MakeCode you can then take a look at CircuitPython or Arduino.)


The block editor is the easiest way to get started with MakeCode. You can drag and drop blocks from the category list. Each time you make a change to the blocks, the simulator will automatically restart and run the code. You can test your program in the browser!

MakeCode has a built-in simulator that re-loads and re-runs code when restarted. This is an easy way to both ensure that our code compiles and simulate it before moving it onto the board. The refresh button re-loads the simulator with your latest version of block code.


CircuitPython is a programming language designed to simplify experimenting and learning to program on low-cost microcontroller boards. It makes getting started easier than ever with no upfront desktop downloads needed. Once you get your board set up, open any text editor, and get started editing code. It's that simple.


Mu attempts to auto-detect your board on startup, so if you do not have a CircuitPython board plugged in with a CIRCUITPY drive available, Mu will inform you where it will store any code you save until you plug in a board.


The Traceback (most recent call last): is telling you that the last thing it was able to run was line 10 in your code. The next line is your error: NameError: name 'Tru' is not defined. This error might not mean a lot to you, but combined with knowing the issue is on line 10, it gives you a great place to start!


If you choose to load libraries as you need them, or you're starting fresh with an existing example, you may end up with code that tries to use a library you haven't yet loaded. This section will demonstrate what happens when you try to utilise a library that you don't have loaded on your board, and cover the steps required to resolve the issue.


There are many different channels so you can choose the one best suited to your needs. Each channel is shown on Discord as "#channelname". There's the #help-with-projects channel for assistance with your current project or help coming up with ideas for your next one. There's the #show-and-tell channel for showing off your newest creation. Don't be afraid to ask a question in any channel! If you're unsure, #general is a great place to start. If another channel is more likely to provide you with a better answer, someone will guide you.


Beyond the Adafruit Learn System, which you are viewing right now, the best place to find information about CircuitPython is circuitpython.org. Everything you need to get started with your new microcontroller and beyond is available. You can do things like download CircuitPython for your microcontroller or download the latest CircuitPython Library bundle, or check out which single board computers support Blinka. You can also get to various other CircuitPython related things like Awesome CircuitPython or the Python for Microcontrollers newsletter. This is all incredibly useful, but it isn't necessarily community related. So why is it included here? The Contributing page.


If you're currently running CircuitPython and would like to start using Arduino, plug in your board, and then load your Arduino sketch. If there are any issues, you can double tap the reset button to get into the bootloader and then try loading your sketch. Always backup any files you're using with CircuitPython that you want to save as they could be deleted.


With bossac version 1.9 or later, you must give an --offset parameter on the command line to specify where to start writing the firmware in flash memory. This parameter was added in bossac 1.8.0 with a default of 0x2000, but starting in 1.9, the default offset was changed to 0x0000, which is not what you want in most cases. If you omit the argument for bossac 1.9 or later, you will probably see a "Verify Failed" error from bossac. Remember to change the option for -p or --port to match the port on your Mac.


We go from any computer on the same network to the browser and type: _PaspberryPi:7100/admin or you can start X from your Raspbian with Midori and go to the next url: :7100/admin (user admin user , password admin).


Assuming no prior knowledge, our detailed practical examples will guide you through building hardware and software solutions using the Raspberry Pi and Arduino. You will learn how you can use thermistors and relays to keep cool and stay in the shade whilst also utilizing electrical motors and photoresistors. These meticulously designed tutorials will form the basis of automating your entire home and getting you started with dozens of potential projects.


Note that running this script on your system "hijack" Raspbian to make it yours. That is, many applications are installed and when you restart, boot to X with Google Chrome in background. Undo the changes is complex. Also it is a very early alpha version, but I've tried it and *it works**. 2ff7e9595c
