“Blinking RGB LEDs with 555s and a handful of 74-series logic The goal of this project is to display colorful patterns on a strip of WS2812 or SK6812 RGB LEDs (aka NeoPixels) without the help of an MCU. Addressable RGB …
The TLC556 series are monolithic timing circuits fabricated using the TI LinCMOS process, which provides full compatibility with CMOS, TTL, and MOS logic and operates at frequencies up to 2 MHz. Accurate time delays and oscillations are possible with smaller, less-expensive timing capacitors than the NE556 because of the high input impedance. Power consumption is low across the full range of power supply voltages.
