Rotary Encoder with Arduino and Nokia 5110 LCD Tutorial

Introduction Today we will take a look at using a rotary encoder with Arduino and displaying rotation data on the Nokia 5110 LCD display. A rotary encoder is an electro-mechanical device that converts angular position or the rotation of a shaft into analog or digital values. They are mainly of two types, absolute and incremental rotary encoders. The output of the absolute encoders indicates the current posi ...

DIY Arduino Battery Capacity Tester

I have salvaged so many old lap-top batteries ( 18650 ) to reuse them in my solar projects.It is very difficult to identify the good cells in battery pack.Earlier in one of my Power Bank Instructable I have told, how to identify good cells by measuring their voltages, but this method is not at all reliable.So I really wanted a way to measure each cell exact capacity instead of their voltages. Few week ago, ...
