Circuit Project Electronic

Today I begs for to advise Simple Electronic Bell Generator , with Linear IC Op-Amp the number is highly popular be number LM741. By when press S1 as a result , will have sound signal bell come out and lead this signal goes to amplify talk at one time with [...]

That be On After Delay Circuit. I uses mosfet in the circuit for delay easy more than the transistor. By have the work of the circuit be when press , S1 , an electric bell will not loud suddenly , must wait for follow the period of time that note. [...]

This be Simple Siren Circuit that build easily. Because of use the transistor 2 pcs only just. Can use 8 ohm size loudspeakers. Which , I uses old loudspeaker , at the sound doesn’t Amen! come to usable with this comfortable circuit. The usability just you presses switch (close) S1 [...]
