Reading out the flash memory is straightforward with an AVR ISP programmer, such as the USBtinyISP, using avrdude from the command line. You’ll need to have a copy of the AVR toolchain– or at least avrdude –installed on your computer. There are easy installers available for Mac (Crosspack) and Windows (MHV AVR Tools) that include this software, along with the other open source tools for AVR development. Linux packages for AVR development are also available.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
