Frequently asked questions
What is the price of Mini Electromagnetic Alarm Buzzer 5V 2-Pin Black in Egypt?
Mini Electromagnetic Alarm Buzzer 5V 2-Pin Black currently costs 9 EGP in Egypt.
Where can I buy Mini Electromagnetic Alarm Buzzer 5V 2-Pin Black in Egypt?
Mini Electromagnetic Alarm Buzzer 5V 2-Pin Black is available from ElectroHub. Compare the offers above to find the best price.
Can I drive it directly from an Arduino digital pin?
It is not recommended. Its current can reach 30 mA, above the 20 mA recommended per I/O pin on ATmega328P-based Arduino boards. Use an NPN transistor such as a 2N2222 with a base resistor.
Can it be used with 3.3 V boards such as ESP32?
It is rated for 5 V, so it should be powered from a 5 V supply. Switch it with a transistor controlled by the 3.3 V GPIO pin rather than connecting it straight to the pin.
