COURSES

PCB DESIGNING:

1.Take a PCB board.

2.Scrub the extra copper with scrubber for shining and reflective surface.

3.Print graphic card with iron box. We have to iron upto 15minutes.

4.Add 100gms of ferry chloride upto 10 minutes.

5.Take the PCB from the boiled water.

6.Scrub again and wash again with normal water.

7.Drill the PCB surface.

8.PCB is ready.

EMBEDDED SYSTEM:

An embedded system is a microprocessor based computer between system with software that is designed to perform a dedicated function, either as an independent system (or) a part of a large system. At the core is an integrated circuit designed to carry out computation for real time operations.

EXAMPLES: Digital camera, Digital wristwatches, Temperature measurement system, Calculators.

BASIC ELECTRONICS:

VOLTAGE:

The potential difference between two electrods. (OR)

The pressure on an electron.

Voltage units is “volts”.

CURRENT:

The rate of flow of electrons at particular points.

Current units is “Amphere”.

AMMETER:

An ammeter is an instrument for measuring either direct (OR) alternating electric current in amperes.

Ammeter are two types. They are:

1.Analog ammeter:

2. Digital ammeter:

VOLTMETER:

The voltmeter which uses the amplifier for increases their sensitivity is known as the electronic voltmeter.

Voltmeters are two types. They are:

1.Analog voltmeter:

2.Digital voltmeter:

TRANSDUCER:

It converts one form of energy into another form.

TRANSPONDER:

Transponder means both transmitter and receiver are built in one device is called transponder.
