How to setup and use k150 pic programmer.

this is Our first project and it is simple 

we will just set a pin as output pin, put 5 volts on it for a while then turn it off again.

Active Low means Device/Pin will be active when Low Voltage (0v) is applied to it. You must apply +5v to vcc to make chip working

For an active high pin, you connect it to your HIGH voltage (usually 3.3V/5V).

Learn how to switch between three pins and give them different values.

display device for displaying decimal numerals from 0 to 9

Seven segment displays are widely used in digital clocks, calculators, electronic meters and other electronic devices.

The display's common pin is generally used to identify which type of 7-segment
display it is. As each LED has two connecting pins, one called the
“Anode” and the other called the “Cathode”, there are therefore two
types of LED 7-segment display called: Common Cathode (CC) and Common Anode (CA)

A liquid-crystal display (LCD) is a flat panel display that uses the light-modulating properties of liquid crystals. Liquid crystals do not emit light directly
LCDs are available to display arbitrary images (as in a general-purpose
computer display) or fixed images with low information content, which
can be displayed or hidden, such as preset words, digits, and 7 segment displays, as in a digital clock. They use the same basic technology, except that arbitrary images are made up of a large number of small pixels, while other displays have larger elements.

A DC motor is any of a class of electrical machines that converts
direct current electrical power into mechanical power. The most common
types rely on the forces produced by magnetic fields. Nearly all types
of DC motors have some internal mechanism, either electromechanical or
electronic, to periodically change the direction of current flow in part
of the motor. Most types produce rotary motion; a linear motor directly
produces force and motion in a straight line.
