この記事を書いているのが2022年5月5日ですが、5月5日現在、Raspbianの64bit版カーネルはβ版しかないようなので、カーネルは32bitを使っているものとして記してます。(64bit版が正式リリースされて気が向いたらアプデするかも) Digisparkとは アメリカDigistump LCC社 ...

Here's a completely rewritten "Arduino as ISP" sketch that can program the ATtiny85, in situ, on the Digispark board via its 6- and 3- pin connectors. It uses an Arduino Uno R3 as the programmer, and ...

自分の工作にてDigisparkの互換回路を作成したので、紹介します。 ATtiny85を使用した開発ボードですが、USB-TypeC端子に対応するように回路を調整しています。 ちなみにDigispark自体はAmazonで安価で購入できます。 本家の回路図は以下の通りです。 電源を外部 ...

The original Digispark is a tiny Arduino-compatible board built around the ATtiny85. This is a custom PCB recreation of that design, including the USB low-speed interface circuit for programming ...

There has recently been a huge influx of extremely small dev board based on the ATtiny85. This small 8-pin microcontroller is able to run most Arduino sketches, and the small size and low price of ...

It might not seem too impressive these days, but when microcontrollers with hardware USB support were more expensive and rare, the VUSB library was often used to create USB devices with an ATtiny85.

This article describes how I have set up a simple “door-sentry” at home. The door-open detector is designed to alert you to an unauthorized entry in a confined area. It uses a little ATtiny85 ...

What should you pick when you want to build a touchless lamp or light switch? A sensor of course! This is a design of a touchless lamp with a common and cheap reflective optical sensor. With a ...
