With this free web app, you can build circuits from scratch using three popular Arduino boards — Uno, Nano, and Mega — and any of the 50+ hardware components, ranging from the basic mini ...

I use that in a lot of Circuit VR posts so you can click on a circuit and see it live. However, the simulator does not save the source code in the virtual Arduino. You have to do that yourself.

Using an Arduino Due (or a Mega for 25% of original speed), the clone can accurately reproduce the behavior of the Altair’s front panel elements. We covered a similar project in the past, using ...

If you prefer to use the Raspberry Pi for your hardware projects, you can readily do so. However, there's an evident disadvantage when you're specifically working with analog components, such as ...

Prototype was constructed & tested using “Arduino UNO-R3” board; Sketch created,compiled & uploaded (to Arduino board) using Arduino IDE0022; Piezo-Speaker in the circuit is a “passive piezo-speaker”.
