Barnstaple Raspberry Pi jam

The Raspberry Pi Jam is this week, Saturday 2nd October, 10-12 pm. This is half an hour earlier than it used to be back in pre-Covid times.

Just to remind you what happens:

It is a drop-in session as always so you can stay as long or short as you wish. Children over 8 years old can be left but parents are welcome to stay. There will be refreshments for which there is a voluntary contribution. Please bring your Raspberry Pi if you have one or any other tech/code project you are working on. If you don't have a Pi, don't worry, we have some to share.

We are still encouraging people to be Covid safe by wearing a mask.

Hope to see some of you there.

Best wishes

Matt Chamings

Add more functions

I have added a few more maths functions to the application and also provided a clear function. There are still a few items to add to help improve debugging but the application is starting to take shape.

Notes

window = Tk()
window.title('Maths Application')
window.geometry("570x150") # w x h
window.resizable(0,0)
  1. The above code is being modified as I go. So I am changing the window size depending on what is being displayed.

  2. I have also made the Window title reflect the purpose of the application.

  3. That the source code now has 'result' as a label rather than output. This will show up future screenshots.

addition app

The code for the above is as follows.

#!/usr/bin/env python
import Tkinter # note use of caps
from Tkinter import *

window = Tk()
window.title('Maths Application')
window.geometry("570x150") # w x h
window.resizable(0,0)

#define button actions
def btn1():
	#convert box text in to integers	
	ent1 = int(entrytext.get())
	ent2 = int(entrytext2.get())
	
	#add the 2 integers and store in variable add
	add = (ent1 + ent2)
	print (add)
	
	#insert value of variable add in	to box outtext 
	outtext1.insert(0,str(add)) # insert response

def btn2():
	#print("subtraction")
	ent1 = int(entrytext.get())
	ent2 = int(entrytext2.get())
	
	#subtract the 2 integers and store in variable sub
	sub = (ent1 - ent2)
	
	
	#insert value of variable sub in	to box outtext 
	outtext1.insert(0,str(sub)) # insert response	
	
def btn3():
	#print("multiply")
	ent1 = int(entrytext.get())
	ent2 = int(entrytext2.get())
	
	#multiply the 2 integers and store in variable mul
	mul = (ent1 * ent2)
		
	#insert value of variable mul in	to box outtext 
	outtext1.insert(0,str(mul)) # insert response		

def btn4():
	#print("divide")
	ent1 = int(entrytext.get())
	ent2 = int(entrytext2.get())
	
	#multiply the 2 integers and store in variable div
	div = (ent1 / ent2)
		
	#insert value of variable mul in	to box outtext 
	outtext1.insert(0,str(div)) # insert response	
	
#clear boxes
def clear():
	#print("clear boxes") # leave in for legacy testing
	entrytext.delete(0, END) # clear input box
	entrytext2.delete(0, END) # clear input box2
	outtext1.delete(0, END) # clear output box
	
btn_tog2 = Button( window, text ='+', command=btn1) # add
btn_tog3 = Button( window, text ='-', command=btn2)  # subtract
btn_tog4 = Button( window, text ='x', command=btn3) #multiply
btn_tog5 = Button( window, text ='/', command=btn4) #divide
btn_tog6 = Button( window, text ='Clear', command=clear) #clear
btn_exit = Button( window, text ='Exit',command=exit)	 #exit

# define some labels
box1 = Label(window, text="1st Value")
box2 = Label(window, text="2nd Value")
box3 = Label(window, text="Result")

#define entry box 
entry1 = StringVar() # this is our entry box
entry2 = StringVar()
entrytext = Entry(window, textvariable=entry1) # this is our entry box
entrytext2 = Entry(window, textvariable=entry2) # this is our second entry box

#define out box 

entry2 = StringVar() # this is our output box
outtext1 = Entry(window, textvariable=entry2) # this is our output box

#display boxes
entrytext.grid(row = 3, column = 2,)  #display entry box
entrytext2.grid(row = 3, column = 3,)  #display entry box
outtext1.grid(row = 3, column = 4,) #display output box

#place labels
box1.grid(row = 1	, column = 2, padx = 5, pady = 5)
box2.grid(row = 1	, column = 3, padx = 5, pady = 5)
box3.grid(row = 1	, column = 4, padx = 5, pady = 5)

#buttons
btn_tog2.grid(row = 4, column = 2, padx = 1, pady = 1) # addition button
btn_tog3.grid(row = 4, column = 3, padx = 1, pady = 1) # subtraction button
btn_tog4.grid(row = 5, column = 2, padx = 1, pady = 1) # multiply button
btn_tog5.grid(row = 5, column = 3, padx = 1, pady = 1) # divide button
btn_tog6.grid(row = 4, column = 6, padx = 1, pady = 1) # clear button
btn_exit.grid(row = 3, column = 6, padx = 1, pady = 1) # exit button

window.mainloop()


The code that I used for a previous application to detect if numerical values have been used is below but provided 'as is' for now.

def response():
		
	msg = "error : must be a text value"

	i = circletext.get()
	y = i.isdigit()
	l = len(circletext.get())
	#print l
	if y == True or l == 0:
		circletext.insert(0,(msg))
		
	else:	
		x = random.choice(RESPONSES)
		circletext2.delete(0, END) # clear prev output
		circletext2.insert(0,str(x)) # insert response

I will integrate a version of this in to the main code.

Addition Application

So following on from the previous posts, I am how sharing a small application, that makes use of what we have been learning.

This presents 2 input boxes and an output box, any values entered in to the first two, the sum is placed in to the last box.

addition app

This is not perfect, but getting there slowly.

We need to:-

  • Fix the name of the button from button1
  • Detect if the user has entered numerical values
  • Detect for empty boxes
  • Make labels more useful
  • Fix spelling in comments
  • Fix clarity of comments

The code for the above is as follows.

#!/usr/bin/env python
import Tkinter # note use of caps
from Tkinter import *

window = Tk()
window.title('App 1')
window.geometry("650x125") # w x h
window.resizable(0,0)

#define button actions
def btn1():
	#convert box text in to integers	
	ent1 = int(entrytext.get())
	ent2 = int(entrytext2.get())
	
	#add the 2 integers and store in variable add
	add = (ent1 + ent2)
	print add
	
	#instert value add in	to box outtext 
	outtext1.insert(0,str(add)) # insert response
	
btn_tog2 = Button( window, text ='button1', command=btn1)
btn_exit = Button( window, text ='exit',command=exit)	

# define some labels
box1 = Label(window, text="Entry 1: ")
box2 = Label(window, text="Entry 2: ")
box3 = Label(window, text="Ouput1: ")

#define entry box 
entry1 = StringVar() # this is our entry box
entry2 = StringVar()
entrytext = Entry(window, textvariable=entry1) # this is our entry box
entrytext2 = Entry(window, textvariable=entry2) # this is our second entry box

#define out box 

entry2 = StringVar() # this is our output box
outtext1 = Entry(window, textvariable=entry2) # this is our output box

#display boxes
entrytext.grid(row = 3, column = 2,)  #display entry box
entrytext2.grid(row = 3, column = 3,)  #display entry box
outtext1.grid(row = 3, column = 4,) #display output box

#place labels
box1.grid(row = 1	, column = 2, padx = 5, pady = 5)
box2.grid(row = 1	, column = 3, padx = 5, pady = 5)
box3.grid(row = 1	, column = 4, padx = 5, pady = 5)

#buttons
btn_tog2.grid(row = 3, column = 5, padx = 5, pady = 5)
btn_exit.grid(row = 3, column = 6, padx = 5, pady = 5)

window.mainloop()

Lego WeDO Session Write up

Today I was involved in a Lego WeDo [2] session at Paignton Library,

I wrote a session plan [1] a while back and submitted this to the library.

The session went quite well, despite a few teething problems with wifi and sotware. We started off using the models I had previously built to experiment with the WeDo kit.

wedo prep

However the kit did seem to prove popular, we had one person drop in and have ago who was already at Lego Club. So the idea that this being within the Lego club area, was good as it attracted further interest.

What we need is a set of our own tablets + software installed and working so that we can just get on and build projects at future sessions.

  1. Session Plan – pdf
  2. Session Plan – LaTeX Source
  3. Lego WeDO
  4. Lego Software
