ARDUINO UNO :

Create a program that displays "AbC" one at a time. For every keypress of PB1 it should cycle from A->b->C and go back to A. For PB2, it is the opposite of PB1, from C->b ->A. PB1 and PB2 can be pressed anytime. For example, If the current display is A pressing PB2 would display C then pressing PB1 will display it back to A and so forth. PB3 is used to blank the display and reset the operation. Sample simulation is given below
