Geometric Progression Basic Guide:-A sequence of non-zero numbers is a Geometric Progression (G.P.) if the ratio of any term and its preceding term is always constant.

A Geometric Progression (G.P.) is given by a, ar, ar2, ar3, ...
where a = the first term , r = the common ratio

Examples for Geometric Progressions
1, 3, 9, 27, ... is a geometric progression (G.P.) with a = 1 and r = 3

2, 4, 8, 16, ... is a geometric progression (G.P.) with a = 2 and r = 2

Nth term of a geometric progression (G.P.)

Sum of first N terms in a geometric progression (G.P.)

### Arithmetic Progression - Write A Program To Find SUM of AP C Programming Examples

We re starting C Programming Tutorial Series.We will try to satisfy our readers by giving some quality content in this series.

To Begin-with we have chosen to start with mathematical series.First series that always troubles students is Arithmetic progression.In this post you will find some basic idea and some useful concepts below.

Arithmetic Progression / Sequence  Mathematically Explained:

Arithmetic progression (AP) is a sequence of numbers in which each term after the first is obtained by adding a constant, d to the preceding term. The constant d is called common difference.

An arithmetic progression is given by a, (a + d), (a + 2d), (a + 3d), ...
where a = the first term , d = the common difference

Sum of first N Terms of AP:

Nth term of an arithmetic progression Tn = a + (n – 1)d
(where Tn = nth term, a= the first term , d= common difference)

Number of terms of an arithmetic progression
n=(l−a)d+1
(where n = number of terms, a= the first term , l = last term, d= common difference)

### String To Float Data Type Conversion Using Microchip Controller PIC16F877A In Flowcode Programming Software

In previous post Float to String Conversion we have seen how to convert Float types of data in String type of Arrays using simple programming techniques.In this project we will be using FlowCode Software for writing a program to convert String Array or Array of Character to Floating type of Data using micro-controller of Microchip company PIC16 Family Micro controller PIC16F877A for testing and Simulation.This Project shows how we are outputting results values to LCD ( Liquid Crystal Display ).Varying the delay and write-erase sequence can be manipulated to different types of combination and lots of desired result.
Flow code program Snapshot(Above).

Here value used is of PI=3.1473

Command used is
string = FloatToString\$ (float)
float = StringToFloat\$ (string)

Above is the Flow code program:

Keypad Introduction:-The invention of the keypad is attributed to John E. Kerlin, an industrial psychologist at Bell Labs in Murray Hill.A computer keyboard usually has a small numeric keypad on the side, in addition to the other number keys on the top, but with a calculator-style arrangement of buttons that allow more efficient entry of numerical data.

This number pad (commonly abbreviated to "numpad") is usually positioned on the right side of the keyboard because most people are right-handed.

### PIC18F4455 ADC Sampling and Writing to SDCard FlowCode Simulation

In this project "ADC Sampling and Writing to SDCard" PIC series micro controller - PIC18F4455 has been used with Liquid Crystal Display (16X2) in Flowcode Simulation Software.As Source of ADC Metal POT (PotentioMeter ) has been used as the variables for desired results and final results are being written to SD Card FAT16 Type.

In this example we are using LCD to display the results of ADC calculation as seen in the examples code and videos.You can manipulate the POT while sampling is going on.As per concept of sampling POT should be kept at desired position to emulate it as sensor and then sampling needs to be done.

Here is the Flow code program:

Flow code Simulation and how to do Video Tutorial:

Little Introduction:An analog-to-digital converter (ADC, A/D, or A to D) is a device that converts a continuous physical quantity (usually voltage) to a digital number that represents the quantity's amplitude.The conversion involves quantization of the input, so it necessarily introduces a small amount of error. Instead of doing a single conversion, an ADC often performs the conversions ("samples" the input) periodically.
