GND - GND (pin 14 on the ATtiny1641). A4 - SDA (pin 8 on the ATtiny1641). A5 - SCL (pin 9 on the ATtiny1641). You can go ahead and try this with the example Arduino interface script provided. Regular ...

Assume that you need to log some of your readings from the input pins of your Arduino Uno (or MEGA, etc.) dev board which needs to work standalone. The proper way is to store the log in an SD card ...

SD cards can be accessed with two modes. The first is the SDIO mode, which is what cameras, laptops, and other card readers use. The second mode is SPI mode. SPI is slower, but much, much simpler.

A maker developer has squeezed an Arduino onto an SD card. He was inspired by Intel’s Edison compute module and he tried to go one better. The result is the SDuino, an ATMega328P processor-based ...

The provided Arduino program is designed to automate the ringing of a school bell and play school prayer or national anthem at preset times. It uses various libraries and hardware components to ...

[Kevin] attached a MicroSD breakout board to an Arduino-compatible clone. When the clone starts up, it searches the SD card for a file called ‘program.hex.’ ...
