We often use Light Emitting Diode (LED) in project as display, indicator or light source. I personally think that LED provides a great visual effect to your project, isn’t it? Today I am going to share some of the tips on using LED that might be useful to your LED project. Continue reading “Tips on using Light Emitting Diode (LED)”
Recently I have made another digital clock as a mini project for my course, Microprocessor. If you are following my previous projects, you may noticed that I have made two digital alarm clocks before, one displayed on 7 Segment Display and the other displayed on Liquid Crystal Display. However in this projects, the digital clock combines both of the display. Another special feature in this project is that no buttons are used to control it, instead TV remote is used to control the clock wirelessly.
There are varieties of digital clock available in our daily life. Basic digital clock usually will have some built in features such as alarm clock, calendar, and thermometer besides display the clock information. Some of the advance digital clock also has features such as AM and FM radio. Most of the digital clocks are using LCD display.

My first two projects related to Arduino are clock related. If you haven’t seen them before, its the Digital Alarm Clock and Digital Clock on 7 Segment Display. Now, I am going to share a project which uses Cheap RF Modules to control robot wireless.
The wireless transmission uses cheap RF module on 433Mhz. This modules can be obtained at a very low cost. Since they are available at low cost, they are not that perfect as compared to more expensive RF modules. Continue reading “RF Controlled Robot Car”
Today I am going to share and explain about a mini project that I made during my free time, which is a Digital Clock displayed on 7 segment display. In this digital clock, there are a few functions available such as stopwatch, countdown timer, temperature display and time settings. Although I think I still can go more besides this 4 functions, which I will try to develop it in the future. Besides that, this clock also has keypad which allows user interface.

In my previous article, GPS Bee Kit (Part 1), I have shown a few methods how to read NMEA messages directly from your computer without an Arduino. In this post, I will explain some basics of the NMEA message and how to make a simple interface with Arduino and GPE Bee Kit.
Global Positioning System (GPS) is a space based satellite navigation system that provides location and time information. Initially, GPS only available for military used in tracking, but now it is available to everyone. GPS is widely used in application such as military, robotics, astronomy and etc. But we can also see the application of GPS in our daily life such as navigation system in advance car or mobile phone with built in GPS. A basic GPS provides information such as location (latitude and longitude), altitude, speed, and time.
Have you ever wondered how people made their projects controlling tons of LEDs with just a single Arduino? Controlling all the LEDs individually requires a lot of pins. So, now I am going to introduce you to shift register. In this tutorial the shift register that we are going to use is 74HC595, 8 bit shift register. By using shift register, you expanded a lot of output pins from your Arduino, that is the best part! Continue reading “74HC595 8 bit Shift Register”
Recently I have made myself nRF24L01 Breakout Board. Firstly, what is that nRF24L01?
In this post, we are going to look on how to control DC motor with L293D by using Arduino. L293D is a Quadruple Half H Drivers which is designed to provide bidirectional control of motors up to 1A at voltages from 4.5V to 36V. Continue reading “L293D Quadruple Half-H Drivers”
In this project, I have made myself a simple digital alarm clock which I could make use of what I learnt before. Making this digital alarm clock involves interfacing with LCD and DS1307 Real Time Clock. If you not familiar with them, I would suggest you to read Liquid Crystal Display HD44780 and DS 1307 Real Time Clock. Continue reading “Digital Alarm Clock”
