Plug the RFID module into the breadboard with enough space around it. Connect the VCC pin to the Arduino's 3.3V (not 5V), and GND to the ground rail. For the data connections, wire SDA to Pin 10, SCK ...

“Supplino is a Quick & Dirty PSU (Power Supply Unit ... through a relay, so Arduino detaches the output power sensing an external pushbutton or on alarm events (short circuit/under voltage ...

Here is an Arduino based circuit with three independent pulse width modulated ... Remember to power the output load(s) from a worthy external dc power supply. Part number of the Mosfet is not very ...

One common mistake beginners make with Arduino is reversing this power connection ... in cases when you're using a 5V supply — from a Battery Eliminator Circuit (BEC) for instance.

It’s an easy to build high voltage power supply that interfaces with an Arduino. After harvesting ... [Andrew] used a MOSFET and MOSFET driver for this circuit (although he says this guy works ...

These materials can mistakenly connect two or more pins, so always ensure that your board and circuit are free of such debris before connecting a power supply to your Arduino project.

Yes, there is a chance to realize one simple non-arduino project of a forgetful plant waterer! If you are looking for this option, digital output of the module must be linked to the little circuit ...

No, what [Bogin] wanted was a serious power supply with short circuit protection and loads of current. He started the conversion by disassembling a 300 watt ATX power supply that uses a halfbridge ...
