The sequences are stored encoded into 2 bits per nucleotide using encode_genome.py.
Current draw is ~3mA depending on which color LEDs are active at the moment (the blue ones are a lot more efficient than the red ones). A CR2032 coin cell should last for at least 10h of continuous use (one run through the sequence takes ~10min, and it automatically shuts off afterwards). Standby current draw is ~0.15µA, should last basically forever (years).
The badge uses an ATtiny1617 microcontroller and colored LEDs.
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.
