Hello everyone…..Today I have taken something out of my flower garden….We all know,plants have their own lives,they can feel just as we feel..but they can’t express it…But what happens if a flower gains the ability to interact with you? Imagine a flower sitting at your desk looking at you,waiving it’s leaves,saying hello and bye….sleeping and waking up….wouldn’t it be fun? While Arduino and Arduino clones are here,why not build something similar ??
Presenting Flora -an interactive flower straight from my Arduino Garden….
Please,before proceeding further,kindly have a look at the video…….

Step 1: Necessary ingredients !

Oh,well,so I built this using-
1. Hard Cardboards
2. 5 Micro Servos
3. Arduino UNO or compatible clone
4. 1 Standard Servo
5. Suitable power supply for the Servos (I had some trouble regarding this)
6. Suitable supply for the atmega board
7. TCRT 5000 modules – 2 pieces, 10Kohm Resistances-2 pieces, 220 Ohm Resistances -2 pieces
8. LDR – 1 piece, 10K resistance-1 piece.
9. A small breadboard for easy connection…..you can also use a PCB if you want,or a veroboard………anything you want.
10. Lots of time to waste….

Thats it……..let’s begin……
Step 2: The head…..
Ok,this is the most complex and most funny part of the whole flower……as you have already seen,it auto closes,opens……so lets take a look at the structure of it…….
1. Draw,cut and colour a circular face like the one in the pic…….I didn’t draw any smile,cause I thought it wouldn’t suit Flora……your choice..
2 make Two hexagonal Cylinders ,such that one can slide inside the other…..it should be hexagon cause there are six petals of Flora…these two would be neck of flora….
3. make the petals out of paper and stick them to the bigger cylinder with small patches of paper,so that they can open and close….se the picture….I have given the pic for three petals,first attach three,when they have dried ,attach three others…
4 Stick the face to the inner cylinder…..see picture
5. Now,slide the small cylinder into the big one….
6. Here comes the Tricky part…..using small patches of paper,attach the petals to the back of the face….just like hinges in an umbrella…..I have given two pics,one with petals closed,one with opened…..study the pics to realize what i am talking about….this part is really tricky….it took me sometime to get it done properly….
7. Now the petals should open and close as the cylinders slide……..if it doesn’t then you must have done something wrong…
8. Cut the backside of the larger cylinder so that we get some paper fringes like those in the picture…..
Step 3:
IMPORTANT– before using any servo,center all of them…….
Stick the head to a micro servo as shown in picture with hot glue…….
And then take two pieces of hard cardboard,stick one to the bigger cylinder and other to the servo horn………..see the position of the screws…..PLEASE see the pictures carefully………
And then attach two more servos to the first one in the way I have shown in the picture……follow these steps exactly…these are quite vital steps.
I don’t have any servo brackets,so I used empty pen refills with some hot glue to make another shaft opposite to the Servo shaft…..see the pictures……And then used pop-sickle sticks to stick the servo horn to the body of the next servo……I will be doing this throughout this tutorial……kindly try to understand it as clearly as possible….
Step 4:
then I used some Ply-wood sticks to make a Servo bracket that would hold the last servo….see pictures.
the shaft opposite to the servo shaft is the empty refill I told about previously……..
