Level converter MAX232 is very essential when we are interfacing the digital hardware (controller) to the computer via serial mode. The computer serial port use RS 232 protocol and controller works on the TTL logic. These two hardware need to synchronize with each other for the proper communications. To solve this problem MAX [...]

DTMF  dual tone is multiple frequency tone which is generated by  phone when the key is pressed. This tone can be used at various applications to control the hardware. DTMF based home appliances is the one of the application of them. When the two phones are connected for the call at that time when the [...]

How Does a Transistor Work

By |2017-05-27T14:36:15+00:00February 25th, 2017|Articles, Electronics|

The Bipolar Junction Transistor The transistor was invented by John Bardeen and W.H. Brattain in 1948. A transistor often called as Bipolar Junction Transistor (BJT) conducts due to both electrons and holes. BJT have two junctions and three terminals. There are two types of transistor: 1. N-P-N Transistor 2. P-N-P Transistor A transistor consist of [...]
