Valentine robot dispenses candy kisses using Picaxe

Picture of Valentine robot  dispenses candy kisses using Picaxe
I had a Picaxe  18m2 project board and wanted to learn more about this microprocessor.  So I created this robot which is programmed to drop candy kisses , stored in a Valentine candy box ,  in  the pattern of a valentine heart.  


Below is a video of it working with the cover on the candy box off so as to better see the candy movement.   I still need to do some tweeking of the code to get a better looking heart but it is not too bad now




Also follows a better video showing the servos processing the candy.

- a swivel castor wheel from Home Depot - 2.00
- a piece of 8 inch shelf board for the platform - 
- 2 servos - Hextronic - Hxt900 - I had but I would say they cost about 5.00 each  
- a box of Valentine Candy - 10.00
- a SN75441 motor control IC - I had but about 2.00
- misc wires . PCB, small pieces of scrap wood , hot glue, headers , zip ties
- 7 double A batteries

Step 3: Prepare the motors and attach to the platform - also attach the swivel castor

I soldered small lenghts of wire to the terminals on each motor and the used wire ties to attach to each front corner. 

The smallest castor that I could fine was this one at Home Depot - it is 1 3/4 inches square.
