Outlined in the shape of a robot's face, this fun circuit uses two LEDs that flash ON and OFF alternately to simulate eyes opening and closing. The flash rate may be adjusted by means of the on-board trimmer pot. Other LEDs are used to identify the robot's nose and mouth. The FK142 is a rewarding use of a few minutes of assembly time and a practical introduction to flasher circuit design.
