and then RA0 should be pulled low (while keeping RA1-RA3 high) so that only units digit display will be active. In order to display all 4 digits, each seven-segment display is activated sequentially using an appropriate refresh frequency so that it will appear that all the them are turned...
The hex file was used for the simulation of the design in Proteus 7.7 VSM professional and burning of the microcontroller for construction. The results were overwhelming as the piece-wise continuous algorithm was implemented, creating rooms for manipulation of 7- segments to form nine - segment, ...
In-between these two set points; any level the water reaches, the seven-segment IC will display the output. When the water table for any particular area is so low that the pump cannot suck the water, an underground sensor detects it and after three minutes, operates an alarm for the ...
