Arduino Uno and all many other big form factor Arduino boards are equipped with a standard 2.1mm DC power jack. Arduino Uno accepts 7-12V dec through this port and the onboard voltage regulator ...

Here we design a simple and small project that is portable power supply (voltage regulator). We know that all electronic devices require DC power supplies. And usually at our homes, the AC power ...

All we need to do is apply a voltage in the specified range to get the desired regulated output to the Arduino. A supply voltage of 6 Vdc to 12 Vdc applied to Vin, or RAW will power the Arduino’s ...

Switch number one connects the 9-volt battery connector to the regulator, serving as a power switch. Each of the other seven switches adjusts the output voltage by 1.5 volts.

For this project, we will be creating a Power Regulator LED Shield Board specifically designed for an Arduino UNO. This shield board will serve two primary functions: Voltage Step-Down from 12V to 5V ...

The Arduino Uno already has a 3.3V pin, but it can only provide upto 50 mA. For my purposes (esp8266), I needed to supply a constant 3.3V with current that could go as high as 170 mA. The Uno's 5V pin ...

A small panel DC digital voltmeter will be used to monitor the 5-V regulator’s voltage of the Arduino. Although there is an onboard LED, the DC voltmeter will serve as a visual indicator alerting the ...
