As you may well know, Arduino’s analog inputs can be used to measure DC voltage between 0 and 5V (when using the standard 5V analog reference voltage) and this range can be increased by using two ...

For testing he’s soldered an IDC plug to the cartridge cover pin interface but this only requires four connections. The Arduino can both send and receive data from the DS lite as shown in the ...

This project is a great example. [Scott Daniels] takes a look at the other voltage measurement options available to AVR chips used by Arduino. If you’ve used the analogRead() function then you ...

In addition to its stackability and low-voltage powering capabilities, the EasyNixie module also offers robust Arduino support. An Arduino library is available to interface with the modules ...

The machine uses a ‘grbl’ controller, which has an Arduino-based circuit that includes ... The circuit on the left can interface with any one of those, plus any 5V logic signal if a dc voltage of 5, ...
