This covers a very configurable and more complex variant of measuring brightness and turning on LEDs.If you are looking for a more basic variant: It all began with a LDR and curiosity. The result is a night light for a ESP8266 like D1 Mini or Raspberry Pi Pico (W) which compensates darkness with many configurable…
Materials you need for this: LDRs (I am using 5528), breadboard, jumper wires, resistor (I used 56k) and a 5V power supply. The MicroPython code has been written for and tested on Pi Pico, Pi Pico W, D1 Mini and NodeMCU v3 ESP8266 .I bought it at berrybase.de and az-delivery.de (not referral links). The microcontrollers…
Jump to: Pico – D1 mini – Pi Zero Raspberry Pico A short Python implementation of a magnetic switch turning on a LED when it is not connected (e.g. window is opened). For simplicity reasons I used the builtin LED on the Pico. You have to use the pull=Pin.PULL_DOWN parameter for the input pin (sensor)….
As a software engineer I often write code that runs (hopefully) fine in the background, does its job and you probably never see it again. That dragged me to buy a unicorn hat for my first Raspberry Pico, as I’d like to see some fancy output of my spare time project. After some time of…
A small helper at night and a nice little excercise on the Pico: an LED that lights up when it is dark and something moves. I used a HC-SR501 as motion sensor, light sensor with digital output, a yellow LED of my Pico project complete kit (330 Ohm resistor with it) and of course the…
The pinout of Pi Pico and Pico W are the same. Just the onboard LED has changed. See below.
Coming from a Java background, I really wanted to and now I am enjoying to learn Python. It is refreshing to see the simplicity and extensive built-in functionality. As I like to see the code working I got me a Raspberry Pico with pins and a Picorino Unicorn hat with a 16×7 RGB LED field…
