"WebMar 10, 2024 · When I program the buzzer (send a HIGH from ESP32), it is permanently on. When I check it against a multimeter, the transistor turns on even when base current is 3.4v (when I though it turns on only if voltage is less than 0.7v). To cross check the transistor and buzzer, I directly connect base to 5v and the transistor is turned off. " - Buzzer with transistor
