DIY Arduino Nano multimeter with LiPo battery, charger and more

Arduino enthusiasts and makers searching for a new project to keep them busy this weekend may be interested in a new DIY Arduino Nano multimeter created by YouTuber Electronoobs. Using a small OLED screen in combination with the Arduino Nano together with a couple of buttons and 16-bit ADC for precise measurements the multimeter has been finished within simple 3D printed casing. Power to the multimeter is p ...

With MCP73831 you´ll charge lithium cells easily and safely

Li-Ion a Li-Polymer cells are becoming a No.1 choice for many applications, where they persuade by high energy density, low weight, low self-discharge and for majority of applications also by their favorable flat shape (Li-Po). Their price is also affordable (in regard to their properties) and so there´s usually only one “difficulty” - to solve charging, or more exactly - overall management of these cells. ...
