Buzzer Features A buzzer is a device used to produce sound. There are two types of buzzer: active and passive. In the active model, buzzer starts playing sound only if connected to a power supply, but in the passive model, we need to send a pulse from the microcontroller to play sounds. The supply voltage of the buzzer is 3 volts, 5 volts and 12 volts. You can download the passive buzzer datasheet here. [wpdm_package id='16469'] Passive Buzzer Module Pinout Buzzer has 2 pins: DATA and GND but t...

ACS712 Current Module Features ACS712 chip is used to measuer DC/AC current based on the Hall effect. This chip is produced in 3 models with different maximum currents. Different models and output sensitivity of each model are shown in the table below: Sensor sensitivity means that, for example, if you use 5 amp model, as input current increase 1 amp, the output voltage of the sensor increases about 185 mV. Note When input is not connected to something and th...
