Send your friends letters with these new Innovation forever stamps from USPS:
Each stamp design features a photograph of a subject representing one of these five fields: Computing (detail of a circuit board), Biomedicine (immune-system cells), Genome Sequencing (detail of a DNA chromatogram), Robotics (a bionic ankle-foot prosthesis), and Solar Technology (detail of a square solar cell). The word INNOVATION is laid over each of the images. Each of the pane’s four rows includes all five stamps, arranged differently in each row to add visual interest.
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.
