I will try it soon
bro need help. i have an inverter circuit with auto cut off function and i don't have an wiring circuit.
Sir what happens if we shot both 1 and 6 no. Pin with 3v
another high frequency signal will be generated, i have just tried after reading your comment. 😅
Thank you for a truly good presentation. I have question for you. Is there any possibility of having three separate tones by using three different switches with single IC? If yes, please advise the necessary modifications to circuit diagram. Thanks!
You can add a selection switch instead of jumpers
Sir can you pl make a circuit on barking sound for home security?
Sir ak video cooler using peltier module par bhi bna do please
Will try
Ok bhai thanks jaldi video lana please
Pls someone share the cheap cost link to buy electronic components products
sir kya hmm esp-01 se i2c communication kr skte hai?
