In this weeks video I’m making an hourglass lamp with light effects that simulate the falling sand when you turn the lamp upside down.
Another cool feature I build into it is the on / off switch, this is hidden inside the lamp and turns on by putting the lamp on the right side. Turning it upside down then turns off the light.
To simulate the sand that is falling I used some Neopixels from Adafruit powered from an Arduino. I chose these because they are relatively simple to program and you don’t need to work with transistors etc. that would be required when dimming regular 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.
