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)

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
