A simple calculation of the circuit is as follows:
Vout = 1.25V x (1 + R2/R1) + Iadj * R2
Since Iadj 100uA,
Therefore: Vout = approximately 1.25V x (1 + R2/R1) ...[Details]
This example uses WinAVR/G 20050214 version. Press key 0, and it lights up. Other keys will not work until you release it.
Press button 1, LED1 lights up. Other buttons can be used at any time.
