 # tinygo-arduino-examples
 Compilation of LCD screen, ADC, and output examples.
+
+## It is suggested you run tinygo with Go 1.15 until [#44557](https://github.com/golang/go/issues/44557) is fixed
+
+## Run an example
+To run any example navigate to the example directory in command line
+
+```console
+cd lcdscreen_adc
+```
+Then flash the arduino. You must know the port it's on. On windows they typically are of the form `COM1` through `COM4`. On Linux the port may look something like `/dev/ttyACM0` or `/dev/ttyUSB0`.
+
+```console
+tinygo flash -target=arduino -port=/dev/ttyUSB0 .
+```
+
+If everything goes OK, some progress bars should pop up and the process should end with a thankful message:
+
+```console
+avrdude: verifying ...
+avrdude: 7036 bytes of flash verified
+
+avrdude done.  Thank you.
+```
+
+You now have tinygo running on your Arduino!
+
+## To create your own "sketch"
+
+1. Create a directory and create a `.go` file of any name. Say we make `twister.go`. 
+2. Create the module. Run `go mod init my_awesome_module` (with any module name you find appropiate for your program)
+3. Start coding in this directory. You may create more files if you wish to distribute you functions
+    * To enable intellisense on VSCode follow the [instructions on IDE integration on tinygo.org](https://tinygo.org/ide-integration/). You basically have to create the same [`.vscode/settings.json`](.vscode/settings.json) file this repo has but with you own `GOROOT` Path (this may differ between installations)
+4. Run `go mod tidy` when done programming. And flash your sketch with 
+
+```console
+tinygo flash -target=arduino -port=/dev/ttyUSB0 .
+```
