using tkinter animation with example py

[tinaburton]

Hello;
I am using your code in the hope of attaching an animation to correspond with the heart rate.
However it doesn't work and I am totally new to python coding. could you help?
here is the code I have included in your example.py
from pulsesensor import Pulsesensor
import time
from tkinter import *
import random

tk = Tk()
WIDTH=1500
HEIGHT=800
canvas = Canvas(tk, bg="brown4", height=HEIGHT, width= WIDTH)
tk.title("drawing")
canvas.pack()

##below is the class to create multiple balls that are coloured
##and move and detect the edge and bounce

class Ball:
def init(self, color, size):
self.shape = canvas.create_oval (10, 10, size, size, fill=color, outline=color, stipple="gray25")
self.xspeed =random.randrange(-1,5)
self.yspeed =random.randrange (-1,5)
def move(self):
canvas.move(self.shape, self.xspeed, self.yspeed)
pos = canvas.coords(self.shape)
if pos[3]>=HEIGHT or pos[1]<=0:
self.yspeed=-self.yspeed
if pos[2] >=WIDTH or pos[0] <=0:
self.xspeed=-self.xspeed

colors=["red4", "red3", "OrangeRed2","OrangeRed4","firebrick3"]
##this is make 100 balls
balls=[]
for i in range (100):

this is to set the colour and size of the balls which is randomised, so they can

            balls.append(Ball(random.choice(colors), random.randrange(150, 200)))

##this is to call the balls
##while True:

p = Pulsesensor()
p.startAsyncBPM()

try:
while True:
bpm = p.BPM
if bpm > 0:
print("BPM: %d" % bpm)
for ball in balls:
ball.move()
tk.update()
time.sleep(0.02)
tk.mainloop()
else:
print("No Heartbeat found")
time.sleep(1)
except:
p.stopAsyncBPM()

Hiya; I have not had time to work on it very much. The main problem was in stabilising the signal from the heart rate monitor. I have been advised to put it inside of a dark holder (like a thimble or something similar). Hope this helps.
