Howdy, I’ve posted two instructables online to help folks connect their Arduino projects to Twitter via usb, no ethernet. My journey began in these forums and I hope that by posting here I’ll help someone else get where they’re going. With simpleTweet you connect a switch to Arduino (any on/off two-state device will work) and whenever that switch changes state (on/off, high/low) the Arduino code triggers a Serial() statement (Serial.write() in Processing; Serial.println() in Python.) That statement is passed through the usb port to your computer where Processing or Python picks it up, evaluates it, compares it to the last tweet posted to your twitter account (by comparing the first word of both messages,) and either does nothing (if the first words match we assume it’s a duplicate) or posts the new message to Twitter.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
