AlanBell / stepper.py

A hello world for the 28BYJ-48 Stepper motor

	#!/usr/bin/python3
	import time
	import machine

	#the stepper motor can be driven by energising the 4 coils in different sequences
	#considering them as binary values converted to decimal (so coil activation 0110 would be 6)
	#we can express the sequences like this
	wave=[1,2,4,8]#wave low torque, low power consumption?
	fullstep=[3,6,12,9]#full step (more torque?)
	halfstep=[1,3,2,6,4,12,8,9]#half steps, longer sequence but can be stepped through faster

silly thing to render QR codes with unicode block characters

	!#/usr/bin/python3
	import pyqrcode
	#first create a code, and convert it to text as a pattern of 0 and 1
	code = pyqrcode.create("westbrit.ie")
	text=code.text()

	def blockify(block):
	#this converts a representation of a 2x2 block into a unicode character
	bricks={
	"0000":" ",
