Need some advice on which Arduino products to get

Other Hardware Robotics
1

I am looking at starting a project to take a signal from a hobby-grade RC controller and using it to control 3 DC motors and 2 servos in a model tank I got a few years ago which came with a shitty set of electronics. I will also need outputs for future expandability to drive LEDs and a speaker.

Which arduino boards should i consider to accomplish my goals?

Thanks

The Arduino isn't a radio. You still need a receiver, that you could connect to the Arduino. But, why? What is the Arduino going to contribute?

Yes, I intend to use a spare Spektrum 5100 I've got to receive. The arduino provides me a means to also drive LEDs and, eventually, a speaker to provide throttle-tied audio effects.

So, "not a whole lot". Any Arduino will be suitable, then. The Uno is the most common of the currently available Arduinos, and has the most libraries, shields, and support.

Well, that depends on different factors:

  • How many Input/Output pins do you need?
  • How shall the Radio receiver be connected to the Arduino (Serial, SPI, I2C)?
  • How many resources do you need for the audio processing (RAM, Flash, Calculating Power)? or do you use a separate audio chip that is controlled over e.g. SPI?
  • What are your physical limits?
  • What are your power and voltage needs and possibilities? (e.g. do you have a 12V Battery onboard or not? What is the voltage and power requirements of your DC motors/servos/sensors)
