The last of the posts on the Hug avoider and the 4Tronix's Eggbit
4Tronix's Eggbit (in fact I bought three of them https://shop.4tronix.co.uk/collections/bbc-micro-bit/products/eggbit-three-pack-special :-) recently) is a cute add-on for the microbit. In three previous posts I looked at eggbit using microcode to produce a hug avoider - warns when people at too close.
In this post using the buttons and adding (via Microbit V2 with its speaker) simple speech
1. Buttons
Pins for the buttons
- pin8 - Green button
- pin12 - Red button
- pin14 - Yellow button
- pin`6 - Blue button
if pin12.read_digital()==1:
#Red Button
blank_it()
if pin8.read_digital()==1:
#Green button
startingMessage()
if pin14.read_digital()==1:
#Yellow button
rainbow()
if pin16.read_digital()==1:
#Blue botton
display.show(Image.ASLEEP)
2. Speech
The basis on the code is take from https://microbit-micropython.readthedocs.io/en/latest/tutorials/speech.html
mess1 = [
"This is the hug avoide",
"please keep back",
]
# Take from https://microbit-micropython.readthedocs.io/en/latest/tutorials/speech.html
for line in mess1:
speech.say(line, speed=120, pitch=100, throat=100, mouth=200)
sleep(500
The speech is difficult to hear but is fun and there are possibly ways to improve this starting with the information on https://microbit-micropython.readthedocs.io/en/latest/tutorials/speech.html
