This project turns the Arduino into an OBD2 on-board diagnostic tester. So, the Arduino can read OBD2 vehicle data and it can read and clear emissions-related diagnostic trouble codes and ...

If you have the KS0108 64 * 128 graphics LCD display and an Arduino then making a trend recorder is just a Sunday afternoon away. The signal either collected on it's analog pin or digital pin can be ...

The Arduino Nano Every is faster, cheaper, and has more memory than it's predecessor, but what is it, and what can you use it for?

Because all the pins are shared, you have the same problem with the Arduino pins, too. If you are driving an output pin with the FPGA, you shouldn’t try to drive it with the CPU also.

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

Note: Tested on the Arduino Nano 33 IoT, Adafruit Itsy Bitsy M0, and the Adafruit Trinket M0, and Arduino Feather M0 (on the accessible pins only); untested on the Arduino Zero, the Arduino MKR series ...

Arduino PIN-Protected Alarm System with Motion Detection An Arduino project implementing a security alarm system featuring PIN code access via a 4x4 keypad, status updates on a 16x2 LCD, motion ...
