Here's my plan. I am tired of shop-bought junk at Christmas and also my kids opening all the advent calender doors by the 2nd December. I know its August but I think Ill need 4 months to get this to work as I am a complete beginner to Python, Pi and anything clever.
Im planning a somewhat different machine, based on projects Ive seen so far. The first is the Skutter as shown in the Mag Pi magazine and the second is either an LED or 7-segment displays to display the date. I know nothing about either!
The rough plan is:
- Have 25 push-to-make buttons on a 'calender' (to be decorated by the wife!)
- A display (LED or 7-segment displays, depending on how hard it is!) to display the day (1-25)
- Each button will make a ground which will be fed to the Pi via the GPIO
- Each button will essentially make the same ground but the Pi will only increment the the number and the day by checking the day's date.
- The present for each day will be collected from a store and handed (over a TBC structure) to the wide-eyes of my kids once the day's button is pressed, by the robotic arm as featured in the 'Skutter' project in the Magpi
What I cant do yet is:
- Creating circuitry and code for the display
- Receiving feedback from the robotic arm as to its position. I could run it open loop but suspect I will get into trouble. The Mag Pi article is due to add more detail which will hopefully be in time.
Thats it for now, if anyone can point me in the direction of helping with the things I cant do, it would be much appreciated. Otherwise Ill tick over until a last minute panic at the end of November.
