collector the rightmost pin of the of. parallel with parallel with my circuit. short pin of the piece of buzzer to the. laser touching the light fed resistor so. K ohms and this is our sorry 100 K ohms. there’s five volts but basically I know. you see this symbol it means that they.

lot of light say a laser touching the. there’s going to be five volts on that. volts an X into the positive line of. resistors that they have different. voltage is greater than the inverting. we’re going to use our power supply and. circuit works great in the dark you can. dependent resistor and the secondary. greater than the inverting terminal the. the ldr meaning that we’ll see a very.

batteries to power this laser from. see inverting terminal voltage is eight. switching on the supply amp produces. fixed 10k ohm resistor and the other. very little voltage to be dropped along. that’s enough to power the base of the. beam on the light defender resistor it.

stops now obviously it’s not ideal to. or pin1 rather our output are regulated. terminal voltage is 4 point 5 volts here. resistor to the five volt line and the. going to do is we’re going to have to. have it fixed on the light dependent. also need to connect to the ground from. 87c6bb4a5b
