The tinyCylon is a multi-mode LED Larson scanner kit with five LEDs that blink or glow in various patterns.
The tinyCylon is built around a Atmel AVR microcontroller, the ATtiny13. It is already pre-programmed with multiple LED sequences. If you have the right equipment and software, you can re-program the chip with your own patterns – even after it has been assembled! The tinyCylon comes with a 3xAAA battery holder with a cover and power switch. Three AAA batteries are required but not included.
