Basic project setup from start to finish

[toddsantoro]

Thank you this was just what I was looking for. Cheers!!!

@toddsantoro you're welcome. Just ask if you get stuck and we'll help you get back on track.

@mfalkvidd I'm stuck again... I wired up the motion sensor and compiled the code on the motion sensor page. It pushed everything to the Nano but I get this: Sketch uses 7,500 bytes (24%) of program storage space. Maximum is 30,720 bytes.
Global variables use 371 bytes (18%) of dynamic memory, leaving 1,677 bytes for local variables. Maximum is 2,048 bytes.
Invalid library found in /Users/xyz/Documents/Arduino/libraries/TAS_motion_sensor: /Users/xyz/Documents/Arduino/libraries/TAS_motion_sensor
Invalid library found in /Users/xyz/Documents/Arduino/libraries/TAS_motion_sensor: /Users/xyz/Documents/Arduino/libraries/TAS_motion_sensor

TAS_motion_sensor is my project folder and the ino file is also named that. WHat am I missing??? DO I need to add the serial gateway stuff to the Nano that has the motion sensor attached to it? I am also using the 3.3v for the radio and the 5v for the motion sensor and I am also using the 2 different grounds provided on the board too. Any help would get me past this first sensor and then I think I will be off to the races.

@toddsantoro From first glance.. you should not put your sketch in the libraries folder but in the sketches folder. Next time please publish the sketch (insert with the "</>" markt in de format menu)

[toddsantoro]

Here is what my Arduino folder looks like: https://www.dropbox.com/s/hfsg3d1xkcoydqq/Screenshot 2016-10-21 16.36.51.png?dl=0

Should I create another folder in there called sketches? Here is my sketch copy and pasted from the example on this page: https://www.mysensors.org/build/motion

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

@toddsantoro something in the Arduino IDE is referencing libraries/TAS_motion_sensor. Do you have any idea what it could be? As AWI said, nothing should expect TAS_motion_sensor to be in the libraries folder.

[mfalkvidd]

@toddsantoro where did you paste the example sketch? What is the file name and in which folder is that file? (use Sketch->Show sketch folder (ctrk/cmd+K) to locate it)

[toddsantoro]

@mfalkvidd I removed everything I have done and started new so that is why you do not see that in the library's folder. I would like to know the exact steps no matter how trivial they are to setting up the sensors project. I am a web programmer and that may be my issue because I know how I would set things up but that does not mean thaty are correct in this situation.

[mfalkvidd]

@toddsantoro the instructions are available at https://www.mysensors.org/about/arduino
After installing the library you can open the examples from File->Examples->MySensors. There is no need to copy-paste from the build page (but that should work as well).

[toddsantoro]

@mfalkvidd OK. I will give it a try. Thanks for your help and patience. I hope to automate my whole 417 sqft home and then help others to do the same.

[toddsantoro]

@toddsantoro Actually I have read that and I am still in the dark. From the Arduino GUI I go FILE > NEW. COMMAND + S and save it where? It defaults to the Arduino folder on my machine with just Libraries directory in it. Do I create a SKETCHES folder and save the project there? I just don't know what to do???

[mfalkvidd]

@toddsantoro save it in the suggested directory, next to (not inside) the libraries folder.

[toddsantoro170]

@mfalkvidd ok... what goes in the file? Copy paste from the example of do I somehow use the motion sensor library? I want to get a basic, best practices work flow going. Again thanks for your help.

[mfalkvidd]

@toddsantoro170 using the example file without modification is usually the best way to start.
