I want to built a 6DOF robot and want to control about 6 or 7 servo's. I want to program a microcontroller and make it permanent (I dont want to change the sketch later). It would be a waste to use an entire arduino (UNO) and an ATtiny85 has to little pins.
So my question is what is te best microcontroller to use and how should I use them (resistors, capacitors, etc.).
(I'm a noob when it comes to electronics)
