it works! how good!

Thanks for this video. Maybe you can help me out with one question: I want to convert a high-frequency pulsed 3.3V input signal to 12V pulsed output (non-inverted). I have +12V connected to supply voltage PLUS. I have GND connected to supply voltage MINUS. The 3.3V pulsed signal (i.e. alternating between +3.3V and 0V) is connected to the PLUS input. GND is connected to the MINUS input. Now here's the problem: the low-voltage pulsed input works fine, but at the op-amp output I get a constant line of the full 12V, no pulse whatsoever (even though I can confirm that the pulsed input goes all the way down to zero/GND between pulses). Note: I used the AD712 in the simulation (one of the original components that come with LTSpice); I could of course not use op-amps at all and instead switch the 12V voltage via a MOSFET that is triggered by the 3.3V signal, but I wouldn't like this alternative, because 3.3V isn't enough to fully open the gate. Any ideas?

whats the formula theortically to calculate Vout here in Inverting Amplifier ?

Sir iska code mil sakta hai

Nice👌👌

Amazing job

Amazing

plase make a tutorial controll relay with voice recognition module and nrf24l01 wireless Home automatic voice command

Hi, I'm trying to make this project. I was able to control the motor with sound module without using nrf24l01 and also nrf is working properly. So there's a problem with my code. Can you share the codes you wrote

you can help me code . thaithinhbkdn@gmail.com

Thanks Prerana ☺️

Keep going👏
