When reed switch is opened, pin 2 of Arduino goes high with the help of the pull-up resistor R2, and the alert signal is available through the piezo-speaker PZ1 (not an active piezo-buzzer). At the ...

By default, the relay is OFF when the Arduino powers up. Manual Override Button: A button connected to the Arduino allows manual toggling of the relay state (ON/OFF). The button uses an internal ...

Transform your ATmega32u4 based Arduino boards into Nintendo Switch-compatible gamepads! This library enables the Arduino Leonardo, Micro, or compatible clones to be recognized as HID game controllers ...

It is in 3.3V level by using a pull-up resistor available inside of the 2.5mm Jack. Now, when this tip gets 0V or Low, the shutter button gets released. This is done using the Arduino NANO. Whenever ...

Electronic, Arduino enthusiasts and makers looking for a project to keep them busy this weekend, may be interested in a cool custom switch created by Dave Darko. That requires users to ...
