Robot Beacon is a rotating light. We have called it Robot Beacon as it has been designed as an addition for a robot, but it can be used for many applications.
It can be used as a mast-head beacon on a boat or as an `all-round` warning light on a bike. Robot Beacon uses a PIC12C508A OTP (One Time Programmable) 8-pin microcontroller.
Even in a project such as this, it takes the place of at least two chips. But the LEDs are switch-mode at a duty cycle of 50% at 500Hz and it would be difficult to produce this with less than 3 chips. Switch-mode saves nearly 30% in current (from 30mA to
