There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra ...

Shift-out: again? Yes, shift-out registers again, now daisy-chained! But let me write down a short foreword. As probably occurs for most of the subjects, especially those related to the Arduino board, ...

On the Uno R4 Minima and Uno R4 WiFi, pin 13 is made an output after reset, so if you do: void setup() { Serial.begin(9600); delay(5000); } void loop () { Serial.println(digitalRead(13)); delay(1000); ...

In this second article we will see a practical application of the daisy-chained shift registers. We want to use four 7-Segments LEDs controlled by the Arduino board. As you can imagine, that is ...

This projects is for anyone who's hooking up a 6502 processor in their own project (such as on a Breadboard) and just wants to be able to monitor the values on the Address Bus and Data Bus. Typically ...
