If your board has no printed labels, check out its pinout diagram documentation (found on the board's Arduino Store page). PWM pins in the diagram have the same tilde sign in front of the pin numbers.

A define creates a label as another code expression ... use the actual built-in LED on the Arduino circuit board itself. If you connect a jumper wire to pin D13 on the Arduino header, then ...

However, getting started with Arduino can feel quite overwhelming at first because you're faced with the decision of what board to buy ... 14 digital input/output pins, and operates at the ...

Hackaday brought you a first look the Arduino MKR Vidor 4000 when it announced. Arduino sent over one of the first boards so now we ... GPIO IP // The GPIO pins controlled by the FPGA start ...

This, of course, led him down the path towards the Sanguino, the ATMega644-based dev board with many more IO pins than Arduino boards based on the ATMega328. Instead of buying new ...

This circuit can be considered as a general purpose daisy-chained parallel shift-out register group for a total of 32 output ports that we can easily manage with our Arduino board (or similar ...

Arduino is a great way ... the temperature sensor socket’s pin assignment is in the correct order for DS18B20 only. When using LM35, the sensor must be inserted correctly — i.e., in the inverse ...
