You can use any kind of push button but I used four pin. Just make sure to connect the correct pins with the circuit.

Thank you 😊

Dear, details are already mentioned in the video.

It's never too late. I picked up on it as an Arduino hobby. 2 years in and I designed my own PCBs. As a plumber you already have a good idea how electricity works btw. At least fluid dynamics helped my understanding of voltages and currents. I always thought electronics is way above my head, but visualizing it like water in a piping system kinda makes it comprehensible for me.

Không, thực ra NE555 được chỉ định để hoạt động trong khoảng từ +5 volt đến + 15 volt và Mạch này được thiết kế cho điện áp khoảng 12 volt.

Cảm ơn bạn! Chúc bạn cũng thật nhiều sức khỏe!

In this video I used Chisel or D type tip.

Thanks

That's the plan!

Thanks

Спасибо за совет! 😊 У меня цифровой паяльник с регулировкой температуры, так что я могу уменьшить температуру без добавления диода.😉

Thanks

Thanks ✌️

It's amazing to see a simple circuit come to life! Building something from scratch and watching it work is a rewarding experience. 😊

@@ele-mechprojects90 it is just normal if you know what you are doing. But ok

I think we can identify it after checking its functionality in a known working circuit and comparing it with the manufacturer's datasheet.

Thanks

Thanks

Thank you so much 😀

Thanks for your feedback! This was just a fun project to demonstrate a simple buzzer circuit. I always welcome suggestions, but let's keep it constructive and encouraging for everyone.

Thank you 👍
