Hey guys
I am trying to build a small clone of a normal RC Remote for my robot , but am stuck as to how to begin with this problem , what do I use ? I saw that there is a PWM Shield TLC5940 from sparkfun that is a digital PWM driver but how would I clone what a RC remote delivers A.K.A 900 - 1900 and not the mentioned high values of 4800 that some people are expierancing. I need 8 channels and the same range as a RC remote , Xbee for communication or what would be the best ? any links and advice would be great!
The first thing you need to do is better define what it is you need. Is there a pe-existing remote that you wish to copy ? What functions does it provide ? What data goes across the 8 channels you’ve mentioned ? At the receiving end what outputs are needed ? Are you driving motors or servos or ??? I assume you’re using an Arduino to create the digitized control signals from some user input devices. What are these devices ? Before you start thinking about what RF modules to use, you need to understand what data is going between them.
