Remote control toys are becoming some people’s favorite, as it bring unlimited of fun to the players. So, if steering miniature helicopters is your interest, then this Helicontrol is definitely your first choice!
Well, Helicontrol is actually a small nifty USB gadget. It’s mostly being used to steer miniature helicopters or quadcopters, especially when the infrared remote control is requiring.
The main purpose of the project is to develop a cheap yet easy to build IR remote control for helicopters. One of the features of the Helicontrol is it must easily attach to a PC without any modification.
For this project, an USB is always the best choice, especially the Atmel (AtmelAvr) is known as the most useful microcontroller. However, it’s quite tricky to solder a TQFP34 package, but it should be fined after some practicing!
Basically, the Helicontrol PCB are divided into four functional units, which as:
AT90USB 1287 microcontroller: It included USB support, 128k flash up to 16 MHz AtmelAvr controller, crystal oscillator up to 16 MHz and capacitor.
A MOSFET transistor (Up to six infrared LEDs to produce a PWM signal).
A RS232 port.
An 8-bit I/O port.
Would you believe it, if the whole project were cost less than $30? It sounds like a very cheap and interesting project to deal with, isn’t it?
