Microcontroller projects and information related to microcontrollers
This is a project I built for work as an add on to our battery tester which is able to test up to six batteries at once. The battery tester is controlled by a PLC and does not show voltages in real time so we had no idea how long the battery runtime was remaining.…
In one of my past arduino projects I accidentally damaged a Arduino Mega328 MCU (or it may have been faulty to begin with) but I decided to keep hold of it in case I needed it for a very basic project that didn’t need many ports. The chip’s pins all functioned OK but it had…
I’ve been working on a new Arduino project; the ultimate alarm clock which shows the time and date on a 16×2 LCD module and features multiple alarms with repeat / auto arm and radio function. I used a Tiny DS1307 RTC and EEPROM module which is a breadboard / veroboard compatible PCB containing a DS1307…
Back in October I posted about a basic NIMH battery tester based on an Arduino nano I made some time back which was a successful project and works quite well however it could only test one battery at a time and didn’t apply a constant current load. It was good but not very accurate and…
Introduction I’ve been playing around with a red 5×7 dot matrix LED display module which I have had in my spares box for a while. I thought about making some sort of scrolling message display as an Arduino project but could not find any more of these modules online as I’d need at least another…
I’ve been using the Arduino for a while now and made a few projects but at work we use the 8051 as the primary micro for our in house equipment. Yeah it’s outdated but Silicon Labs have taken the original 8051 design and vastly improved it with clock speeds of 100Mhz. It can easily outperform…
A close relative of mine has been having lots of wifi connection issues over the last few months but just on a couple of devices. A scan of the wifi neighborhood showed only a couple of signals from adjacent houses which were too weak to cause a problem. I tried changing the channels, 150 or…
***Updated*** now version 5 which has a vastly improved display layout and better voltage reading accuracy. Download can be found towards the bottom of this page. During my clearout of old junk I came across an LCD display fitted into a small plastic case with a PC parallel cable attached which was originally used for…
