reviving my 30 year old legos with the new power functions, yay! boys are asking why the walker can’t see when they want to stop him. hm… plan to upgrade the quadruped with the servo for steering and the IR remote. (read more)
After seeing someone’s floppy-drive orchestra, I was inspired to reuse my stepper motors from another project. The music starts as a MIDI file, pre-processed in C# into a text file. The Raspberry Pi runs a Python script to watch the play/stop button and play out note data via serial to the Iteaduino Mega, with a Dual Stepper Shield to drive the two steppers and two servos.(read more – and see the tour inside here)
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.
