What is a Single Pole Double Throw Switch? A switch may contain one input terminal that can move between two outputs. Thus, we are speaking about a Single Pole Double Throw (SPDT) switch. Here, you can wire 2 units simultaneously. [Read more…] about What is a Single Pole Double Throw Switch (SPDT)?
What is a Single Pole Single Throw Switch?
What is a SPST Switch? A switch may contain one movable input to contact one output connection point (a terminal). If this is the case, we are speaking about a Single Pole Single Throw (SPST) switch.
The working principle of such a switch type is very straightforward. Its only application within a circuit is to keep a single device on or off. That is why it is commonly named as an on-off switch. [Read more…] about What is a Single Pole Single Throw Switch?
How to make LED Cube 4x4x4 Using Arduino
Welcome to my tutorial on how to make led cube 4x4x4 with Arduino Uno.
In this page I just hope to give you a little bit of clarity. Maybe some tips or tricks kind of what you need how to build this cube. Which is pretty sweet you can see.
In the description of it working so that’s going to be the final product. But in this one I’m going to show you how to make it so without further ado.
Lets’s start!
The LED cube consists of four 4×4 matrices (horizontal layers). All the LEDs on each layer are connected to one another by anodes that are wired to the А1, А2, А3, А4 pins of the Arduino NANO board.
The cathode legs of every LED are soldered together to form the vertical columns of 4 LEDs, each of which is connected to the pins L11 – L14, L21 – L24, L31 – L34, L41 – L44. [Read more…] about How to make LED Cube 4x4x4 Using Arduino
How to Safely Discharge a Capacitor
I don’t want to sound boring, however, before starting this tutorial I would like to refresh your memory on some physics, and below is a little bit of a theory.
Capacitor is a device made up of two metallic plates separated by insulating material. It is an electric and electronic component that stores electrical energy during power surges and releases it back to the circuit when the circuit voltage drops below the capacitor’s voltage value. When the circuit voltage drops, capacitors may regulate the voltage of the circuit until they get total or partially discharged.
Capacitance is the ability of a system to store an electric charge. Farad is the unit of electrical capacitance.
