Each of the 14 digital pins on the Arduino Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive ...

The pin represents one of the input/output pins on the Arduino. In this case, digital pin 13. The mode variable is one of the two constants INPUT or OUTPUT. When INPUT is used, ...

Arduino digital pin headers have an inexplicable 160mil gap between the banks. The Seeeduino has the standard row for shield compatibility, but has an additional row spaced at standard 100mil ...

I connected the LCD display according to a slightly modified design of Arduino's tutorial, with LCD VSS to ground, LCD VCC to power, LCD RS pin to digital pin 7, LCD Enable pin to digital pin 6 ...

Now to the hardware setup that consists of an Arduino Uno and a 128 × 64 I 2 C OLED display. The OLED display used is a 5-V tolerant type with just four pins: VCC, GND, SDA, and SCL. You can, of ...

It transpires that folk have been busy writing ‘cores’ – the name for code that adapts Arduino code to run on different hardware – for several other bare chips, and some have 20 pins – plenty. Have ...

We have feature quite a few cool clocks here at Geeky Gadgets, the latest one is the work of Andrew O'Malley, the DOTKLOK, which is an open source Arduino digital clock.
