Interfacing with Rotary Encoder
Rotary encoder or rotary switch are mechanical sensors that can track the direction and distance of a rotation movement. It is commonly used as digital volume knobs (where the rotation is endless, unlike a potentiometer). More advance types of rotary encoders are used on robots to track the distance of its’ movement. I got this rotary switch breakout board from …
Skylab SKM53 GPS Module
I got this GPS Module from ebay at just under RM 80. It’s not cheap but this is the cheapest solution to get GPS signal for any electronic projects. The module has a built-in GPS antenna and also the Skylab SKM53 chip. The moment when I tried to plug the module on a breadboard, I realised that the pitch of …
Digital Alarm Clock
I’ve decided to make a Digital Alarm Clock for my diploma final year project. Before I start this post, here’s a video about it The Hardware Features The Making of the Digital Alarm Clock This Digital Alarm Clock project started its’ life on a breadboard, and with a brand new ATmega328P MCU bought from Cytron. Together with …
BBFuino from Cytron
BBFuino is a breadboard-friendly Arduino created by the guys over at Cytron Technologies (cytron.com.my) It is sold for RM 55 but I managed to grab it for only RM 1 cent! Thanks to their 1 cent promotion I managed to get other amazing stuffs as well. Back to the BBFuino. The BBFuino is not a complete Arduino in the sense …
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 …
Arduino SD Card
The Arduino Ethernet Shield I bought last week also has a MicroSD card slot on it. It allows the Arduino to read or write files on the memory card and this is particularly useful for data logging purposes. Yes, you can use the EEPROM on the Arduino but it’s only limited to 1024 bytes and it’s not removable. This shield …
