Fixing a Car Dent
Hi. This is probably my first ever post that it’s not related to electronics. It’s about my pride and joy. My 2004 Proton Saga. Well, maybe not so much pride because most of the installment were paid by my dad apart from a few months when I was working. This car was passed down to me when I learnt how …
5 Digit 7-Segment Display
I’ve been working on a digital clock project so I thought I will get 4 units of 7-segment displays and put all of them on a PCB to show the time. When I was at the electronics store, I stumbled upon this. I bought this because it has 5 digits on a single package and it looks much neater than …
DS1307 Real-Time Clock IC
The DS1307 IC is used to accurately count time and date. Once set, and as long as it has power, it will continually count the time by itself. It uses the I2C bus to transfer data to the microcontroller. Below are the key features of this IC. Real-Time Clock (RTC) Counts Seconds, Minutes, Hours, Date of the Month, Month, Day …
Arduino Tip : Turn your Analog pins into Digital I/O
Recently I’ve just found out that I can actually turn my Analog input pins into Digital Inputs or Outputs. It’s really simple. Usually for the digital pins, we write instructions such as digitalWrite(13, HIGH). To do that with analog pins, simply use digits 14 to 19. Pin 14 being Analog 0, 15 being Analog 1 and so on. Or you …
Arduino Twitter Feed Viewer
The reason why I got the Ethernet Shield is because I found that there are lots of interesting things to do with it. One of it is to make the Arduino obtain live twitter feeds from the Internet and display it on an LCD. I got the inspiration from the example Twitter sketch in the Ethernet Library. I just modified …
