Breadboard Regulated Power Supply 5V/3.3V

image-903
In any electronic product or project there is always a need for a source of power for the system to work. This is called a power supply. To get power hassle-free to the power lines of a breadboard can be a challenge, you will need a convenient and safe way to get either a regulated 5V DC or 3.3V DC depending on your application  on your breadboard power rails. In this project we are going to design step by step a simple  Breadboard power supply that takes power from a 6 to 15V DC power supply and outputs a selectable 5V or 3.3V regulated voltage using a switch. This board can be easily inserted into a breadboard using a .1" (0.254 cm) headers mounted on the bottom of the PCB. Pins labeled VCC and GND plug directly into the power lines of a breadboard.

Arduino Shield Tutorial – Make Your Own Relay Shield

Arduino shields are boards that can be plugged on top of the Arduino PCB to extend its capabilities. This makes prototyping with Arduino plug and play. Instead of soldering or wiring external devices or sensors, you can simply hook your board with a shield. This speeds up development time even for absolute beginners. This is a practical tutorial, we're gonna build a fully working complete Arduino Relay shield, we're gonna go through all the steps

Arduino shields are boards that can be plugged on top of the Arduino PCB to extend its capabilities. This makes prototyping with Arduino plug and play. Instead of soldering or wiring external devices or sensors, you can simply hook your board with a shield. This is another practical tutorial, we're gonna build a fully working complete Arduino LCD Keypad shield, we're gonna go through all the steps, we'll start from scratch explaining and simulating the circuit diagram in Proteus, then we're gonna create a Printed circuit Board with Eagle but any PCB design software can also be used, then we're gonna generate the manufacturing files to manufacture the PCB with PCBWay our favorite low cost PCB manufacturing company and finally were're gonna test the operation of the shield with a simple Arduino sketch.
