I was finally ready to buy an Arduino, I got into Google, and found that they had multiplied quite a lot: arduino, freeduino, seeduino, netduino and all the others. Where they differ is installed, the microcontroller, memory, number of inputs/outputs, interface, size, price and, in the end, even the name.
All these boards are compatible with additional modules, such MotorShield and the like?
How many sensors, displays and other gadgets can connect to the Board at the same time? And is it possible to increase this number by connecting any additional modules?
What level projects will fit in 16KB/32KB/256Kb flash memory?
Does it make sense to take a ready-made whales with bells and whistles included? Or is it better to buy them as needed?
Want to do some poseuse-flying-riding robot that reacts to every change in the environment.
What would you recommend?
