摘要：At this present time, a lot ofelectronic circuits based on digital, and the resulting datais "logic 1" and "Logic 0" or high and low, but data cannot be immediately known. For that based on the aboveproblems, the author wants to create a tool that can showif the letters H (High) on the seven segment, which meansthe voltage is high value, and an L (Low) the mean voltageof low value. In addition, this tool can also produce hightones and low tones that came out of the loud speaker,so that the digital data on an electronic circuit, can beknown. Based on trial results that have been done, thenthe obtained data as follows: seven segment display anL-value if the incoming voltage 0-0.9 volts. Seven segmentdisplays the letter H, if the incoming voltage value of 3-5.5volts. But the stress is worth 1-2.5 volts, seven segment,did not show any letter.
