G15 Cube Servo on Mobile Robot

The new cube servo, G15 from Cytron Technologies is amazing actuator. Beside the angle/position control feature (like a standard RC servo), it also offer continuous rotation :)[youtube]https://www.youtube.com/watch?v=yGuZDgbj4xI[/youtube] We are going to show a simple mobile robot construction using G15 as

Introduction to Microchip’s MDDFS – Reading and Writing Files (Microchip 16-bit microcontrollers)

In this tutorial, you will learn how to read and write files in a Micro-SD card using a microcontroller. Do not worry as you will be using Microchip’s Memory Disk Drive File System (MDDFS) libraries to help you to do all of these immediately. One thing about the library is, it requires a lot of microcontroller’s program space. The dsPIC30F4013 will be used in this project since it has 48KB of program memory.

Construct a 8x8x8 LED Cube

Ever heard of an embedded electronic project called LED cube? Actually, this project had been done by many embedded electronic hobbyists due to its interesting display effects by lighting up LED Cube in certain patterns. The LED Cube lighting patterns can be controlled by microcontroller based on the program loaded into it. In this tutorial, user will be guided to build up a 8x8x8 LED Cube in step by step.
