First I would like to introduce myself. I’m Sven I live in The Netherlands. I have ordered a Arduino Starter Kit and a Arduino Mega. The reason why I want to use Arduino is:
I’m currently busy with building an 1:14 RC truck. In this model I would like to build in lights (fog lights, winkers, brake lights etc).
This is the current situation. The servo’s are being attached to the Spektrum receiver and this works fine. But I would like to attach all the servos and Leds to the Arduino.
I would like to program multiple programs in the arduino. In the first program I can use the servo’s for steering, lift an axle etc.
In the second and third program I can turn on/off the specific lights.
I have thought about it and I think it’s possible to switch between the programs with a 2-position switch on my RC transmitter. Everytime I hit the switch it will increase an integer by 1.
With all this info I have made an schema with the Arduino and the current devices combined:
I’ve read that I need an external power supply for the servo’s. Is this schema correct? Any tips and improvement are welcome. If anything isn’t clear, let me hear you.
