How to - Change the setting for your Bluetooth Module

Hey guys, few months ago I bought a bluetooth module to play around with bluetooth. It is 

(JY-MCU Bluetooth Wireless Serial Port Module for Arduino)

 Just yesterday, I get to know that I can actually change the device name, baud rate, and also pair code for this device. 

It's pretty simple to do this ! Believe it or not, it is simple !

PCB Terminology

Hey guys, sorry for long time never update my blog. Was busy for the past few months with my academic and university activities.

This will just be a very short post where I will share some useful document about general PCB terminology.

For those who are into PCB designing, I think this document would help you in understanding the common terms used as a PCB designer.

My Workbench

Hey all, welcome to my blog ! Sorry for did not update my blog for like 2 weeks already. Was pretty busy on training and organized my things. 

Are your tools like stripper, cutter, test pen and some others tools been placed everywhere and sometimes it is hard for you to find them when you want to use them !  Well, this problem always happen to me where my workbench is pretty messy.  So, I thought of making myself a simple board to place all my tools and equiments.

How to - Sense temperature (LM 35)


        Hey guys, today we are going to look through something that is very common in our life - Temperature. I understand that the surrounding temperature in Malaysia is quite high, probably around 32 - 34 degree celsius due to the hot weather in Malaysia. Have you ever wonder how can you meausre the surrounding temperature ? By guessing it ? Hahaha. Well, let me introduce you to a temperature sensor - LM 35 ( Celsius)

Active-HIGH Vs Active-LOW Button

 In this post, I am going to talk about a very simple thing about button. You can connect your button normally in 2 ways when dealing with microcontroller :
  • Active-HIGH
  • Active-LOW

BB Prince

Hey all !

Just today I received a small gift from my friend - a BB Prince. What is a BB Prince actually ?

BB = Breadboard

Awesome Electronic Self-Learning Website !

Hey all, was pretty busy since I posted my last post. I was busy learning and designing new things for the past few weeks. Nevertheless, I will still find some time to get my blog updated with some useful information.

In this post, I am not going to talk more. I would like to recomend to you guys a very good electronic circuit websites.

I will made a list for those useful website :
1. Electroschematics 

 - This website provide various categories of projects such as audio, arduino, power supply, radio, solar and etcs.

HC-SR04 Ultrasonic Sensor

Have you ever wonder what type of sensor that you can use to sense for obstacle ? Well, in this post, I am going to explain a brief detail about using a HC-SR04 Ultrasonic Sensor for sensing obstacle.

The HC-SR04 sensor is using the sonar to determine the distance to an object like what you know about bats or dolphin. It comes complete with ultrasonic transmitter and recevier module.

Some features of the HC-SR04 ultrasonic sensor :
  • Power supply :  +5V DC
  • Working current : 15mA
  •  Measuring angle : 30 degree
  • Ranging distance : 2cm - 400cm 

Datesheet HC-SR04

A very good video preview on ultrasonic sensor !

A DS1307 is a pretty simple , inexpensive and easy to use real time clock IC. This IC can count date and time accurately. Once the time and date is set, it will continue its counting if the power(backup battery) is there ! The backup battery ( coin cell battery) is there to keep the DS1307 counting operation if the main power supply is cut off.

Eagle Cadsoft PCB Design Software

     Recently, many have been asking me what software I am using for the schematic drawing for my DIY PCB.
So, I decided to make this post and share with everyone about the PCB drawing software that I have been using all this while.

Wireless Relay

        Relay is an electrical operated switch that people normally used when they want to control a higher voltage circuit from a lower voltage circuit.

        Current flowing through the coil of therelay creates a magnetic field which attracts a lever and changes the switch contacts.
