Circuit Project Electronic

This is Logic Digital Tester Circuit. It uses the level input about 5V and use the integrated circuit LM324. Be Main Part electronics perform Drive All LED. Then use Current very low about 10mA by have potentiometer be formed fine the value threshold give [...]

This circuit is a Logic Probe. It indicates the logic state of the node of any TTL logic circuit. To do that, we have to supply the probe with the same power of the circuit that we want to analyse: same Vcc and same GND. To check the logic level, we must connect the “Test” [...]

This circuit is supplied as a hobby project. It uses indicator LEDs to display various logic states for high, low, rising pulse, and falling pulses. It can be used as a general troubleshooting tool and is particularly useful for debugging TTL and CMOS logic circuitry.
In this design, the first 74LS00 gate acts as a buffer [...]
