How to Build a Simple LED Cube 4x4x4 - Part 4

Software
The software is derived from my earlier LED cube, the charlieplexed version. Of course the "hardware layer" had to be changed, because physical control of the LEDs is different. But the rest is very similar.

To add a bit more structure, I partitioned it into several files. There is the main routine (in LEDCube444.c), the file HWControl.c for low level hardware support and a collection

Electrical Contactors AC1, AC2, AC3, AC4

Image
Electrical Contactors Utilization Categories:- Electrical Contactors are categorized according to the current making and breaking values for contactors. This will depend on the following: The type of load to be controlled (Inductive load, Lighting load, Motor load, Resistive load, Capacitive load) The operating cycle conditions. For any applications there are different contactors available depending upon load application which every electrical engineer you must know before designing any systems.  You may have often seen the ratings described on contactor name plate depicting various parameters. One of most important to be considered are as described in this article.  AC1 - These type of contactors are used for Non-inductive or slightly inductive loads they are used for Heaters which are resistive loads. AC2 - These type of contactors are used in Starting of slip-ring motors AC3 – They are particularly used for Starting of squirrel-cage motors and sw...
