Enough with the learning let’s get our hands working and build a custom ICSP cable to program/bootload an Arduino, an ATMEGA328P (chip used in Arduino UNO) , or any other AVR microcontroller. Things ...

They used the webaudio API to send serial data to a remote Arduino. The hack uses a FET, a capacitor, and a few resistors. They didn’t quite build a real modem with the audio.

[Steve] wanted to do some ARM development and set his sights on the Game Boy Advance as a development package. In order to get his code onto the device he build an Arduino-based communications cabl… ...

The Arduwire UNO is an innovative shield designed for the Arduino UNO development board. This shield enables users to perform a variety of tests on cables and harnesses, including continuity, open ...

Using an IoT SIM that works on cellular networks in over 100 countries, the Electron's basic data plan starts at $2.99 per month for 1 megabyte of data and 99 cents for each additional megabyte.

Arduino devices have had the option of a GSM linkup for awhile, but getting that cellular link to truly strut its stuff hasn't always been easy, even for those of us who'd be inclined to program ...
