In this circuit, a MOSFET protects a reverse-connected battery from excessive current. The MOSFET conducts only when the battery is correctly connected, which lets the battery charge or discharge. In ...

Shift-out: again? Yes, shift-out registers again, now daisy-chained! But let me write down a short foreword. As probably occurs for most of the subjects, especially those related to the Arduino board, ...

Here are 4 simple 12V power supply circuits with output voltages around 12V. First power supply circuit is built with BD139, one zener diode and a few passive components. Each of the schematic is very ...

“Supplino is a Quick & Dirty PSU (Power Supply Unit) made with some widely available breakout boards, an Arduino Nano (or an Arduino Nano Every) and a graphical LCD. Power output is given by a DC/DC ...

IoT and wearable devices have become essential tools in our everyday lives. From health monitoring wearables to smart home sensors, they rely heavily on battery power to function. However, optimizing ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...
