Why yes I do have an question.You are the one who built the probe, even better, do you have a specific question?
You're right. So how do I do it?The most important feature of a logic probe is the ability to display extremely short pulses (using a monostable effect).
Just showing HI and LO on a LED is not worth any more than, well... A LED.
Dear Sir,
I guess providing that the chip is within specs. But won't one of the LEDs always be on since the output of the chip will be either high or low? There is no tri-state.Hello,
The probe uses the 74ls14 chip, so it will be conform the LS-TTL norm.
