Logic Checker


Posted on Jun 9, 2012

Simplified logic checker. Logic voltage levels have the ability to display LED (Of course I (^_^;).` H `in the LED is green,` L `and red LED lights, and so both the open and goes out . But not only that was put on the ability to detect narrow pulses. In doing Shottomaruchibaibureta be extended to a short, pulse, this pulse of about 100ns in LED flash you can see it. This is handy for checking the presence of the signal and strobe.
