Send messages of love with the love box from Marcel Sör:
The Lovebox is a project I learned about through a Make: magazine article from 2019. A reader notified ThingPulse – of which I’m a co-founder – because the project’s Arduino sketch relies on an open-source display driver provided by ThingPulse.
When the Lovebox receives your message for a loved one, the heart wiggles until she/he lifts the lid and reads the message on the display hidden inside the box.
The initial app implementation polls a GitHub Gist for new content. If it sees a new message (text or image) it displays it and sets a servo in motion to which the heart is attached. When the lid is opened a photoresistor (acronymed LDR for Light Decreasing Resistance, or light-dependent resistor) registers the extra light in which case the app stops the servo.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

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.
