[Original camera setup to manually produce 360° animation.]I wanted to automate the creation of 360° animated GIF photos. This sort of thing has been done many times in various ways by many people, so I am re-inventing the wheel here, but I don't have their solution to hand. The obvious way to do it appeared to be to use an Arduino board to control a stepper motor and synchronize the camera. I had previously created such animations by manually moving the camera and taking many photos, then ma…

Overview To help train electrical engineers in digital electronics Digital Equipment Corporation (DEC) produced a digital logic trainer together with a training course. It allows students to connect up various configurations of basic logic gates following a workbook to get a hands on idea of what it was all about.

There are a huge number of Arduino shields, but some seem to be poorly documented and/or discontinued and it is hard to find a complete set of data on them and drivers for them. [Arduino Shields] Overview Arduino shields are generally mini circuit boards designed to plug directly on top of an Arduino micro-controller board and provide some extra functionality. Some are designed to plug into one specific Arduino model only, others might fit one or more models. A wide range is available, alm…

I have two LCD modules, recovered from now forgotten devices, that I wish to use in Arduino projects. These are 2 line by 20 character LCD status displays, controlled by two NEC μPD7228 controller chips. Overview I looked for an Arduino library that would talk to this chip-set, but failed to find one. I did find a small sample of code written by H. Imayuki (8 Mar 2010),

Overview In the late 1970's an evaluation kit for the Intersil all in one Analog to Digital (ADC) chips with built in display drivers, ICL 7106 (LCD) and ICL 7107 (LED), was produced. These very successful chips are still produced today and are the engine of many digital multimeters. Although the boards are labeled
