Microcontrollers are the backbone of any intelligent digital circuits where you design and implement the circuit according to the need and design constrains. Arduino are the most popular microcontrollers used and Arduino IDE is one of the easiest IDEs to work with. ATTINY85 USB Development Board is a small and cheap Development board which supports programming by Arduino IDE and has a USB port to connect to the PC. It has a plethora of different shields which can be attached to it to increase its functionality. Overall, it is one of the easiest and cheapest ways to get started in the Microcontroller Programming. It has 6 port with several functions. Depending on the programming (with Arduino IDE) can it have 6 digital I/O, 4 analog inputs or 3 PWM outputs. It can be powered by a USB port or an external power supply of 6-20V DC.
