For a school project I'm making a remote controlled car with a moving camera with 2 servo's.
I'm done with the electronics for my motor and now I'm trying to set up my servos and the remote control.
I have to use a hardware controller with my own electronics in it ( dificult to find a controller) and I also have to make an app for android, but I never made an app and I found some sites that say I need to use bluetooth but that can't reach far enough and they use arduine which I'm not allowed to.
If you are going to drive 2 more servos without a microcontroller, you will need more channels on your remote. If you are going to use an android app to control he vehicle, you are going to need a microcontroller of some sort to interact with.
Maybe you could give us more specifics about your project?
I’m using 2 dc motors to make it drive with a H-bridge and a MOS driver. each motor is powered by PWM and 2 pins from the microcontroller to make it go forward and backwards.
I haven’t done the electronics for the servo’s yet and the camera and the transmitting of video is blackbox (so I don’t have to say anything about it).
As the servo’s have to be PWM controlled aswell I have to use 2 micrcontrollers because I can’t find any with 4 PWM pins
As for microcontrollers you can use PICAXE 28X2(equivalent to Atmega328). I really can’t understand why you can’t use Atmega microcontrollers. Anyway prefer rechargeable batteries (NiMh, LiPo), alcaline perform poorly in robots.
