A Windows 10 IoT core application that switches on an LED based on digital light sensor reading. Story It took me some time to figure out reading the status of the Digital Light Sensor is straightforward and it simply depends on reading the GPIO value! The idea of the project is very simple, just switch […]

The Raspberry PI or R-pi from http://www.raspberrypi.org/ is well known these days. It is not an accident that I have one, I have been doing Linux stuff since 1991, and professionally since 1996 I can not skip over these developments, have to keep up with the new kids. 🙂 Times have changed, hardware has become very affordable,

IMSLP is one of the greatest things to happen in the classical music world in recent memory. For those who don’t know, IMSLP.org is an online library of any and all sheet music that is no longer under copyright protection. You can find pretty much anything written by Beethoven, Bach, et al up until early

A quick little post for my future reference really. Wanted to get an i2C Analogue to Digital Converter (ADC) working on a Raspberry Pi. No real application as yet, but sure to be one in the future. Most of the information to make this work was taken from posts by Grumpy Mike on the Raspberry Pi

The original plan for the Analog-to-Digital Converter was to use the Dallas 1-Wire system and use the DS2450 1-Wire Quad A/D Converter which was advertised as being a 16 bit device but after buying two of the chips which are around £5 each I found that near the end of the spec PDF they say

Initially, I was working on a maze solving robot. Instead of using ultrasonic and infrared on Arduino Mega for wall following like my friends did, I try to do something different using the digital compass and Raspberry Pi 2. This experience is totally new for me as I’m now using Python instead of C++ (well

The Raspberry Pi is a great little educational computer, but all models of the Raspberry Pi miss a critical ingredient for electronics experiments – an Analog to Digital converter. I am constantly working on upgrading my lab, and one of my needs is to measure many channels of analog signals, with reasonably high precision. I

Raspberry Pi has a Broadcom BCM2835 chip, which controls 26 GPIO (general purpose input/output) pins. There are C library or RPi.GPIO python package available online that can be used to control the pins. The RPi.GPIO package is by default included in most Raspberry Pi system, such as Raspbian, a RPi version of Debian linux system. One
The goal of this project was to create a low cost Raspberry Pi Media Panel–a nice looking screen that could stand in the living room or attach to the refrigerator with the primary purpose of streaming personal photo and video content full time, but also be able to do some other cool things when needed…like

All right this is the review on the next two lessons on linear hall sensors. Lesson 02 uses an analog linear hall sensor and an analog to digital conver IC ADC0832. The lesson 03 uses a linear hall sensor with added comparator, which allows some sensitivity tuning of the sensors by adjusting the potentiometer. The
