This is a short guide to explain how to program an AVR microcontroller (like what powers an Arduino Uno) directly from the GPIO pins on a Raspberry Pi. Why would you want to program an AVR from a Pi? If you’re building up an AVR-based board or product from scratch you’ll need some way to program code onto the chip. Typically dedicated tools like the USBtinyISP are used to program an AVR through its in-circuit serial programming (ISP or ICSP) pins, however with the latest version of the avrdude programming tool you can actually use Linux GPIO pins to program an AVR directly–no dedicated programmer required! This guide will walk you through how to install and use avrdude to program an AVR microchip or Arduino through its ISP pins with a Raspberry Pi.
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.
