After Tomic finished creating the eye, he snapped a photo and applied a special effect that completely transforms how we view the image. Using manipulation software, he inverted all of the colors, which reversed what was black and what was white. This has a profound impact on the picture, and it suddenly looks like a graphite drawing rather than one made from salt.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
