Tilt-a-Rainbow Mini: Demo Mode

All 64 pixels light together in red, green, blue, then white, 1.5 seconds each. The colors stay dim on purpose, so 64 lit pixels draw only about 300 mA.

One purple pixel visits all 64 spots in strip order, 10 steps a second. Every row runs left to right, so after pixel 7 it jumps back to the left edge, one row down.

A green bar slides down the rows, then a blue bar slides across the columns. Straight bars show that xy() turns a column and a row into the right pixel number.

A yellow smiley with blue eyes blinks, then winks at you. Each frame is a picture typed as 8 lines of letters, and a color key turns every letter into a color.

Eight pictures slide in from the right, one after another: a smiley, heart, alien, ghost, rainbow, flower, fish and rocket. Each one stays still for about 2 seconds.

MOVING RAINBOW! slides past in rainbow letters, 9 columns a second. Each letter is a tiny picture 5 pixels tall. Change the text in MODES to show your own words.

Red, green and blue dots drift slowly and bounce off all four edges. Each dot starts in a random spot and heads off in a random direction.

Seven dots, one for each color of the rainbow, move faster than in mode 7. It is the same module as mode 7, with different settings.

Twelve colors race around, each with a fading tail. Every frame, each pixel keeps 215 out of 256 parts of its color, so the old spots fade away bit by bit.

Five colored drops fall down the matrix, each at its own speed, leaving fading trails. A drop that reaches the bottom starts again at the top.

Colored rings start at random spots, grow, and fade away, like raindrops landing in a pond. A new ring starts about every 0.7 seconds.
