It is hard to know which calculations you have in mind. Could you tell us something about what the device is supposed to do?

The Device its a Level meter and Activates an alarm and a motor , when it reches certain values, and the LCD shows constantly the level.....the things needed to be calculated are all the resistors, the Voltage source components and currents and voltages

Since this is in the homework forum, I think Nara wants to show calculations that would be used to spec the value of each component in the schematic.
Like (Vcc-VD1)/10mA=R2 and (Vcc-VD2)/10mA=R3

Exactly! at least i would need to know wich Calculations must be maid to calculate every component for Optimal Operation.....in the circuit all values are labeled....but they were label Empirically.....those values weren´t calculated....
