When AC mains power is on, step-down transformer X1 generates about 15V AC and converts it to above 18V DC after rectification and filtering. DC voltage thus available is split into two: one for ...

It is really easy to test the Arduino shield. Just place the shield on to the Arduino UNO and give it a 12V supply from the input barrel jack. The shield can take input voltage of maximum up to 34V ...

In this project we are going to make a Buck Converter Circuit using Arduino and N-Channel MOSFET with a maximum current capacity of 6 amps. We are going to step down 12v DC to any value between 0 and ...

The main power source is the ship's batteries, which are charged using photovoltaic panels. The voltage on the accumulators is between 13 and 14 V which is fine for the stepper motor driver, but too ...

Arduino based Fire Alarm – Circuit and Working. Fig. 2 presents the circuit diagram for the fire alarm using a flame sensor and Arduino Nano. The system is powered by a step-down transformer (X1), a ...

Set up the Arduino Uno with the required libraries and connect the Arduino USB host shield and Bluetooth dongle. Upload the provided Arduino sketch to the Arduino Uno. Confirm that the Arduino Uno is ...

For instance, let we have a +12V dc power supply and we want to obtain +5V dc to feed our load that tends to draw 0.5A under 5V. From the series 78, the LM7805 is suitable for this purpose. When we ...

A pair of 12V, 10A, 4MHz step-down power modules from Texas Instruments measuring 11 x 15mm are said to be 20% smaller than any other 10A power module-based solution. The SWIFT TPSM84A21 and TPSM84A22 ...
