Garage Bugler Alarm - Arduino Nano / Pi Pico, PIR sensor and magnetic door switch.

I made alarm with an Arduino and it stopped downloading at the end so had to switch to a Pi Pico using Arduino IDE and C+ for my first time. I prefer C+ to Python so I will be using this in future.

LOST ME THE SECOND MUSIC STARTED.

you aint got a garage mate lol well not last time i was over . i got something i need you to look at 8 channel mixer that wont power up could be any thing i have no multimeter since the lcd died lol iots old style capacirtors in there lol

Workshop then lol. Have you not been in the Workshop? Might be easy if it`s got no power.

I also hate buglers - that nasty sound, not a even as cool as real trumpet, let alone a fluegelhorn - playing some throwback screeching sounds. Bugles suck

Lol when I typed burgler the spell checker put a red line under it so I thought it was wrong. I`m not good at spelling. I gave up with English as it`s not that logical at school. I was programming at 12 year old so my mind was more interested in that. Great comment. Made me laugh mate.
