The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

2-Axis analog Joystick The connection of Arduino controller to joystick sensors and button is very simple as shown in the layout diagram. As stated, The joystick can be moved in two dimensions ...

Switches People make pushbutton switches on the Arduino way, way too complex. Set a digital pin to INTERNAL_PULLUP mode. It attaches a ~20kΩ pullup resistor to the pin, dragging it high.

We’ve taken the versatile processor behind the Arduino Leonardo, and combined it with a Direct Digital Synthesis chip, which makes generating analog signals incredibly straightforward. Then, we ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

Whereas a typical scale would then simply show the resulting number on an LCD display, [Mirko] decided to use a moving coil meter driven by the Arduino’s analog output.

Analog Link It is also possible to read the amount of moisture present in the soil (for judging whether the soil is wet or dry) by linking the analog output (AO) of the module, to one analog input (A0 ...
