Interface SD Card with PIC Microcontroller

October 26, 2014 | Anonymous | 0 comments

SD memory cards, especially the ones under 1GB are cheap, relatively easy to interface and provide vast amounts of memory for imbedded control.

This device lets you 'talk' to sd cards through your serial port. Communication is in ASCII so you just need a terminal program to access it. (Note: the photos shown are of the rev-1 device with various changes, documentation is for the rev-2).

HARDWARE

SD sockets are available from SparkFun Electronics. The socket needs to be surface mounted so it was placed on the foil side of the single sided board (mouseover image above to see). The connections are close to 0.1 inch centers, so the layout was not difficult.

The PIC16F819 was chosen for its

How to find Point of Interests in nearby location of a GPS coordinate?

August 27, 2014 | Siddiq Ansari | 0 comments

Global Positioning System- GPS is diversely used nowadays. Google Earth or Google Map is making life easier if someone want to view the road to a particular destination or when someone want to find out nearby hotels if he/she has his/her current GPS location coordinates. As a developer while using API of google map, when someone want to find out nearby places or point of interest within certain radius, then there is two ways which can be implemented. Both ways are about using mysql queries but only difference is the execution time.

Let’s start with an example.

If we have find out 10 nearby hotels and sort them by distance; we are provided with: a TABLE having hotel list with hotel name

Control Speed of DC motor by PWM

August 5, 2014 | Siddiq Ansari | 0 comments

How to control the speed of DC motor? This becomes a major problem if someone is doing some robotics projects or where DC motors are used. So, here is a solution provided.

Pulse width modulation (PWM) or duty cycle variation methods are commonly used in speed control of DC motors. The duty cycle is defined as the percentage of digital ‘high’ to digital ‘low’ plus digital ‘high’ pulse-width during a PWM period. Fig. 1 shows the 5V pulses with 0% through 50% duty cycle.

Fig 1: 5V pulses with 0% through 50% duty cycle

 

The average DC voltage value for 0% duty cycle is zero; with 25% duty cycle the average value is 1.25V (25% of 5V). With 0% duty cycle the average value is 2.5V, and

Shilajit: A review

July 20, 2014 | Suraj P. Agarwal, Rajesh Khanna1*, Ritesh Karmarka | 0 comments

Shilajit, also known as salajit, shilajatu, mumie or mummiyo is a pale-brown to blackish-brown exudation, of variable consistency, from layers of rocks in many mountain ranges of the world, especially the Himalayan ranges of the Indian subcontinent (Kong et al., 1987; Srivastava et al., 1988) (Fig.). It is also found in Russia, Tibet, Norway and other countries,where it is collected in small quantities from steep rock faces at altitudes between 1000 and 5000 m. Shilajit samples from different region of the world, however, vary in their physiological properties.

Shilajit, an ancient traditional medicine has been ascribed a number of pharmacological activities and has been used for ages as a rejuvenator and for treating a number of disease conditions (Acharya et al., 1988). Modern scientific research has  mystematically validated a number of properties of shilajit and
