Rotary Encoder 500ppr Resolution

Encoder 500 Banner

In this post, I’ll be reviewing the B-106-23983 Rotary Encoder. It is made by ESB and has a resolution of 500 pulse per round. This is a high-end rotary encoder and is used in critical automated applications. It is mostly found in industry machines rather than consumer electronics. It costs RM 350 as stated in the cytron website. Below are …

Bluetooth Mini Robot

Bluetooth Mini Robot Banner

Got another new robot kit and decided to create a bluetooth controlled robot with it. It’s from DFRobot and it’s called the MiniQ. Here it is assembled. Created a simple circuit on a donut board with a L293 H-Bridge and Arduino Nano. It is powered by a 2 cell Lithium Polymer battery. Typically each cell provides 3.7V so that amounts …

Programming Arduino using Atmel Studio 6

Arduino Atmel Banner

Arduinos are based on Atmel microcontrollers, and they can be programmed using Atmel’s native IDE – Atmel Studio 6. The main reason to use Atmel Studio 6 instead of Arduino IDE is because it provides better performance, Arduino IDE might be easy to use but it is slow because of inefficient compilation. It takes more cycles to execute an instruction …

Using Internal Oscillator on ATmega328P

Intosc Banner

I’ve been working on a project which involves a very small PCB layout, and I found it very hard to route unless I remove some unnecessary connections. Therefore, I decided to remove the external oscillator and use the internal 8MHz oscillator. To do this, you’ll need a programmer. I’m using a cheap USBASP bought from ebay. To enable the internal …

74HC595 Shift Register Tutorial

Sr Banner

Shift register is a sequential logic circuit consisting of flip-flops. They are created mainly to store digital data in the form of bits. The basic working principle of a shift register is the user would enter data into it sequentially and the data will move from the beginning till the end of the shift register. Any bits that ‘flow’ out …
