I tried to give this version a character, as I always felt there is somebody "thinking inside the box", so here I tried, I hope I succeeded to give "her" a life!
I am really happy to share with you all the steps, with all hopes that you will be easily building yours and giving it a bitter or better character! My version is based on Arduino, you may think it is an overkill, but given the flexibility it gave me, I think it is worth it.
Here is a video of everything put all together. Later, we will move into the parts, steps, schematics and code
Let me know your comments and/or questions if any.
Hope you enjoy!
Step 1: How it works?
If you saw the above video, each time the switch is toggled, the machine responds in a different way, and this is done by simply writing different functions with different timings in the Arduino code, (I am calling them "Moves"). Each time the switch is toggled, I am calling a new move until all are done, I start over. You can add as many moves as you want, as long you have enough memory on the Arduino.
The Arduino is always ON, this is why I added a switch for the battery to save some power when the machine is not in use. I am already planning to use an interrupt on the switch, instead of the current simple HIGH/LOW detection, and coupling it with sleep mode. This shall save power when the machine is not in use ,and also allowing it to be always ready (but this will also complicate the code) So, for now, it is just a simple ON/OFF switch, and the board is always powered.
