A timer-controlled doorbell device has been developed using two 555 timer ICs in monostable mode, combined with a relay ...

Gallium nitride, a semiconductor renowned for its efficiency and high-speed capabilities, has long been recognized as a ...

Unsupervised learning is demonstrated using a device ubiquitously found in today's technology: a transistor with high-k -metal gate. Specifically, the charge-trapping phenomenon in the high-k gate ...

The reverse-conducting insulated gate bipolar transistor (RC-IGBT) has several benefits over a separate IGBT and diode solution and has the potential to become the dominant device within many power ...

GitHub - sanjeevivs/Audio-amplifier-transistor: The project demonstrates the use of NPN transistors (BC547) in amplifying a weak audio signal. It highlights how transistors can be used as amplifying ...

ESP32 Mist Blower Control This project controls a 5V DC blower fan (model EG50040S1-CF50-S9A) using an ESP32-WROOM-32E and an NPN transistor (BC547) as a switch.
