[Damian Peckett] has implemented an Apple ][, its 6502 processor, and a cassette port, all on an Arduino Uno. If that wasn’t enough, he also uses a PS/2 keyboard for input and outputs analog VGA.

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52 .

However, it has some more horsepower than the Uno, as it offers more digital I/Os and analog input pins than the Uno, and is a good alternative for this board for applications that need more hard- and ...

Our project is to make a 9V battery adaptor plug to be used at DC jack/socket on the Arduino board. Fig. 1: Arduino board. This DIY 9V battery power adaptor is built using a drinking straw, aluminium ...

The Arduino UNO WiFi Rev.2 is the easiest point of entry to basic IoT with the standard form factor of the UNO family. Whether you are looking at building a sensor network connected to your office or ...

Arduino: 1.8.8 (Windows 10), Board: "Arduino Uno WiFi Rev2, ATMEGA328" In file included from C:\Arduino Projects\libraries\FastLED\examples\ColorPalette\ColorPalette.ino:1:0: ...

This sketch should be intended as a modificable skeleton, where you should add your program; the skeleton sketch, when compiled for Arduino UNO or Arduino Duemilanove, occupy less than 2,5 Kb of the ...

The Arduino UNO R4 boasts a 3x performance increase over the UNO R3 and , in addition, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.

We must cover the new Arduino devboard recently released, the Uno WiFi Rev 2, with integrated Wi-Fi connectivity in an IoT-friendly form. There's so much to say about the recent announcements from ...
