using tkinter animation with example py

tinaburton commented 6 years ago

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. Tina
