Notes on Nuts and Bolts...

Notes on Nuts and Bolts             A screw thread is a helical groove on a shaft. When used for delivering power, it is called a drive screw. Drive screws aren't really all that efficient, as they loose a significant amount of power...

What is a constant power load , Constant current load and Constant resistance load ???

Constant resistance load:            In a constant resistance load the current will go down in proportion to the voltage drop as the resistance is fixed and the load must follow ohms law. Heaters approximate this type of load. Constant current...

What’s the Difference Between Sleep and Hibernate ?

Sleep Mode Sleep mode is a power-saving state that is similar to pausing a DVD movie. All actions on the computer are stopped and any open documents and applications are put in memory. You can quickly resume normal, full-power operation within a few seconds. Sleep mode...

Difference between USART, UART, RS232, USB, SPI, I2C, TTL ...

UART - Universal Asynchronous Receiver Transmitter: It is one of the most used serial protocols. Most controllers have a hardware UART on board. It uses a single data line for transmitting and one for receiving data. Most often 8-bit data is transferred, as follows:...
