5.1 Blockdiagram

Big electronic schematic diagrams can be very complicated. To simplify such a complex diagram we often use 

a blockdiagram. In a blockdiagram we imagine several electronic circuits as a block with their own function. So 

with the above blockdiagram we can see the function of the Sky Walker electronics. We will explain each block 

more detailed now.

Motor

section

 Power supply &

 Lamps section

Filter 

section

Timer 

section

Microphone

sensor section

Lightsensor

section

Power supply and Lamp section

Provides all electronic circuits with power. The Lamps are an ON/OFF indicator

Light sensor section

Detects a difference in light intensity

Sound sensor section

Detects sounds

Timer section

An RC network, regulates the walking time

Filter section

Filters the disturbing power supply signals from the motor

Motor section

Switches the Motor ON and OFF
