Two new little tools for your tinkering time with Arduino
Two new Arduino products are available starting today from the Arduino Store. Read below for details!
This shield allows you to connect devices to your Arduino using a USB port, for example game controllers, digital cameras, phones, keyboards, etc:
- it is based on the MAX3421E, which is a USB peripheral/host controller containing the digital logic and analog circuitry necessary to implement a full-speed USB peripheral or a full-/low-speed host compliant to USB specification rev 2.0.
- it can be used with the “USB Host Library for Arduino” hosted by Lauzus from circuits@home on GitHub (click to download zip).
If you want to see how to use it, take a look at this tutorial from Officine Arduino which used it to add wireless to an RC Car.
——————————-
It’s a tiny AVR-ISP (in-system programmer) based on David Mellis’ project FabISP and useful to anyone needing more space on the Arduino board. Uploading a sketch with an external programmer can be used for three main reasons:
- remove the bootloader and use the extra space for your sketch
- burn the bootloader on your Arduino, so you can recover it if you accidentally corrupt the bootloader.
- when you use a new ATmega microcontroller in your Arduino, and you need the bootloader in order to upload a sketch in the usual way.
