Arduino – multi-cell voltmeter

Right at the start of the saga which is my multi-cell voltmeter/potential BMS, I considered and rejected the simplest way of doing this, namely using voltage dividers to drop the voltage from the cells down to within the range of

Arduino – multi cell battery voltmeter progress

As reported in the last post on this topic, I soldered headers onto the two 16 channel MUX and started testing. Since then I have spent a bit more time trying to get it all to work. The major change

Arduino – voltage drop

I started working again on the multicell voltmeter, I soldered some header pins onto the two 16 channel multiplexers, and plugged them into a breadboard with arduino. Some basic testing proved that my optimism was completely unfounded. So using best

Multi Cell Voltmeter

The big order of Arduino related products has started to arrive, the key components, the Arduino mega 2560 clone and the TFT LCD screen arrived two days ago, along with some of the voltage sensors, and most of the jumper

New Project – Electric Bikes, Arduino and Programming

Exciting times – a new project, bringing together Electric Bikes, Computers and Programming! During my troubles with batteries (which are pretty much sorted now) I realised I needed a way of looking at the voltage of all the 12 cells,
