Back in Experimenting with Thermistors, I described the challenge I had with Bitcoin miners heating the warehouse area I use as a training space. Recently, we had three small upper windows installed that I can open. The original wind...
I know how to use plain UART on the Pico, with receive interrupt. See advanced_uart.c.
I also know how to make the UART show and work as a COM device. See hello_usb makefile.
I'm looking for help on the following: use the USB as a COM, and ...
Introduction
In this blog I explain how I created a solution, which displays real-time train arrivals data for a station platform (i.e. in one direction) on a 20x4 character OLED display using a Rasberry Pi PICO-W board. The motivation behind this p...
I saved up for 6 weeks to buy a 7" Touchscreen and I don't know how to install it on my Raspberry Pi B+ V1.2 because there are no instructions in the box and I can't find them online. The box doesn't even say what model s...
Hi all ! Hope everyone is well.
Just want to share my latest project - a water cooled Raspberry PI.
Why ? Well, since I was a teenager (I'm from the 80s) that I wanted to have a Water cooled Desktop PC. I first saw one in 2004 at a Lan Party (...
Interfacing Nine DS18B20 Temperature sensors with Raspberry Pi and Displaying sensor data Using Python
I have gone through some tutorials for interfacing the DS18B20, In those, They have given the explanation of how to interface the DS18B20 using Ar...
