Introduction The purpose of these pages is to introduce the student and hobbyist to electronics projects. My hope is generate interest for those thinking about entering a high tech field, or simply to have fun. Ive been a part time adjunct professor at a local community college teaching electricity and electronics. My electronics website reflects what Ive taught or been asked to look into by visitors. I have 4. 0 years experience in electronics from vacuum tubes to modern solid state and industrial controls. In college I had a year each of physics, chemistry, and biology along with C, C. Pascal, and assembly. How to use this Website. This site has been up for about 1. Arduino, some PICAXE Microchip PIC and semiconductor components such as transistors, zener diodes, etc. I assume the user has at least some knowledge of Ohms Law and can use a volt ohm meter. All of the example circuits have been built and tested I do not use simulation software such as SPICE. I dont use or have circuit boards for the projects, one will have to design their own. When I do build a projects I use point to point wiring by hand. I have limited financial resources and part of the lesson is use what resources one has. Nothing here is intended to be used as commercial product or used in one. Most of the projects use low voltages, but the few that dont such as AC power controls are presented as information only you assume all risk. New Arduino Stepper Motor Coil Winder. You.

I taught myself the coding for Arduino, PICAXE, Raspberry Pi, Microchip PIC, Debian and Slackware Linux, CSS etc. I approach in a way to give my students a basis for their own projects. Every page on this website was hand coded by me every project built and tested. My education philosophy is learn the basics, find working examples, then use what works as a foundation for further learning. Modify and try new ideas. Id say my job title would be applied technologist. First and foremost read this safety warning. Unless one wants to use batteries, the only practical solution is a plug in the wall power supply. General Electronics Learning and Projects. At 3 inches long this basic Arduino does ten times what the KIM 1 will do. Cost is under 5. Arduino Micro controller Projects. My Arduino section is growing. For example we can interface the thermocouple amplifier and an LCD display to the micro controller to display the temperature in say the flue of a wood stove. Again the idea is modular, small projects that can be built into bigger projects. For more technical details on the Arduino see ATMEGA1. Arduino Micro Controller Projects. Arduino Microcontroller Projects presents a number of tested projects and examples for Arduino. Maxim Filter Design Software. The emphasis is hardware control which suggest one has an electronics background. Its also helpful to have a background in digital logic and binary code. The projects will explain this as needed. What differs here is I avoid the use of Arduino only code and code libraries in order to port the basic code to Python or Microchip PIC C. Raspberry Pi and Linux. Raspberry Pi and Linux is an ARM processor based mini Linux computer clone. It has addressable hardware IO to connecting external circuitry. These projects are in Python a high level interpreted language finding many modern applications. Here I again concentrate on hardware interfacing and an introduction to setting up the operating system in Debian Wheezy and installing a real time hardware clock. The Linux I setup here can be used in any Debian based system even a common PC. Python is SLOW compared to C used on Arduino, but is great for a user interface. So I look into alternative interface setups to use say An Arduino to handle low level electronics. I also use light Debian programs for Raspberry Pi ported over from Damn Small Linux and Puppy Linux because as a PC Pi is slow and weak. Many of the operating systems often touted elsewhere some will hardly operate. Instead of LXDE I use JWM and Openbox. Here I concentrated on building a fast Linux based operating system to get some weaknesses in Raspberry Pi. Connecting PC Printer Port to External Electronics. Below are listed a series of projects using pyparallel and electronics. We will use a common PC printer port to learn basic python and electronics interfacing. Starting with routines I wrote to aid students Id advise walking through this in sequence. Have fun and send comments andor corrections to lewisbvu. Connecting a PC Printer Port to Electronics with Python is closely related to Raspberry Pi. It too is a nearly identical Linux system but differs in being designed to use a hardware printer port as I O to connect electronics projects. The projects here too are in Python and with modifications will work on Raspberry Pi and vise versa. It differs in I never bothered to setup the I2. C interface found in Raspberry Pi instead interfaced an Arduino to better handle low level electronics. Now a available for download a custom live Linux distribution to use a PC printer port for electronics control without installing or altering the PC in any way.

Microchip PIC Projects PIC1. F2. 55. 0, PIC1. 6F6. A, PIC1. 2F6. 83. Microchip PIC1. 8F2. BOLT system board but can be used without it. Centered on the PIC1. F2. 55. 0 is programmed in C like Arduino and the programs are often interchangeable. I present a lot of code examples. Also included in that section is assembly language projects for the PIC PIC1. F6. 28. A and PIC1. F6. 83. While cheap and versatile controllers theres a steep learning curve in using assembly. Introduction to PIC1. F6. 83 Programming. PICAXE Microcontroller Projects. Finally we come to the PICAXE Microcontroller in this case a medium range PICAXE 1. M2. While built hardware wise on a Mircochip PIC controller it has an easy to learn built in proprietary basic. Its designed for students rather more than serious applications. The PICAXE series of micro controllers rank as the easiest and most cost effective way to use Microchip processors. I wanted an easier and less expensive way to introduce my students to the PIC micro controller. Here I hope to get those starting out past poorly written literature and lack of simple working code examples.
