Project #27

Quick-Slow Blinker

Project #26

OBJECTIVE:  To make cute sounds and flash lights. 

Quad Red Blinker

Build the circuit and turn on the right slide swtich
(S1). The red lights in the Rover body are blinking
and a tone is heard. Use the knobs on the sound &
recording IC (U9) to adjust the blink rate and tone.
Turn on the left slide switch to shut off the sound. 

OBJECTIVE:  To make cute sounds and flash lights. 

Build the circuit and turn on the right slide swtich
(S1). Lights in the Rover body are blinking and a
tone is heard. Use the lower knob on the sound &
recording IC (U9) to adjust the blink rate and tone.
Turn on the left slide switch to slow down the blink
rate by adding a much larger capacitor to the circuit.
