There are times when you don’t need much processing power for your project but you do need a lot of I/O pins. It often doesn’t make economic sense to choose a larger microcontroller just to get extra ...

A while ago I received a couple of I/O port expander modules that use the I 2 C protocol. Using that Chinese module, you can use only the SDA and SCL pins of your Arduino, or any microcontroller ...

There are a few different ways of getting firmware onto one of AVR’s ATtiny85 microcontrollers, including bootloaders that allow for firmware to be updated without the need to plug the chip into a ...

Arduino has two new boards out which deliver connectivity – the Arduino MKR WAN 1300 (LoRa) and the Arduino MKR GSM 1400. The Arduino MKR WAN 1300 delivers LoRa low-power WAN connectivity, and the ...
