Art project early stage

Hi Phil

This is a really sensitive movement detector - you might be able to contain its’ range / orientation with some artistic bit of metal …

Wanting to create: sound triggered by walking past

Hi Jessie And a friend provided this link to a simple RADAR sensor Some info here and a HEAP of info about it here And a simple code to test it - you could merge in the MP3 Player code instead of the led.on line from machine import Pin led = Pin(25, Pin.OUT) radar = Pin(22, Pin.IN, Pin.PULL_DOWN) detect = False while True: detect = radar.value() if detect: led.on() else: led.off() I have tried it - it does give a solid trigger but is interesting to aim, in…

It is really simple to interface - just takes one pin

machine import Pin
led = Pin(25, Pin.OUT)
radar = Pin(22, Pin.IN, Pin.PULL_DOWN)
detect = False

while True:
    detect = radar.value()
    if detect:
        led.on()
    else:
        led.off()

cheers
