@mehmet.bkr5: DIY Electronic Siren | 3.7V Circuit How does a simple transistor circuit generate a siren sound? This project uses BC547, BC557, and TIP42C transistors, with an added on/off switch. Sound Notice: The professional siren audio is added for demonstration. The actual circuit produces a different sound. Safety Notice: Some visuals may be AI-assisted. Electronic circuits can be hazardous. If you’re inexperienced, do not build or test the circuit without qualified supervision. #SirenCircuit #ElectronicsProject #BC547 #TIP42C #DIYElectronics@İSKOÇ 47 21 ( 01 ) @annebebekdünyası @𖣂Ö𝖒𝖊𝖗𖣂
