Interfacing GPS module with computer using terminal software

In this post, we will learn how to interface GPS module with laptop/ computer using terminal software like Bray's terminal.

Stuff required:


  1. GPS module
  2. 12V 2A dc adapter
  3. USB-TTL converter
  4. Female to female jumper wire
First of all, power up the GPS module using 12 volt adapter. 
Download any terminal program. I am using bray's terminal.

DIY dtmf module and interfacing with arduino uno


In this post, we are going to make dtmf module and interface it using arduino.

My prototype

Theory of  DTMF:
Full form of dtmmf is dual tone multi frequency. The DTMF telephone keypad is laid out in a 4×4 matrix of push buttons in which each row represents the low frequency component and each column represents the high frequency component of the DTMF signal. Pressing a key sends a combination of the row and column frequencies. For example, the key 1 produces a superimposition of tones of 697 and 1209 hertz (Hz). Initial pushbutton designs employed levers, so that each button activated two contacts. The tones are decoded by the switching center to determine the keys pressed by the user.

Simulate program in proteus

In this post, we will cover how to simulate program files in proteus.

Proteus is a simuation software used for simulating analog/ digital circuits as well as for simulating embedded based projects. It can used for simulating 555 based, transistor based circuits. It's a very good tool for hobbyists, students and professionalists. This is not a freeware however one can download the trial version from the official website or simply purchase it.

Step 1: First of all, choose the components from the library by simply right clicking on grid area.

Search component in proteus library
Components from libraries
Step 2: In keywords box, type atmega 16 and  select appropriate components from the listed item.
