Warning: Shock Hazard – Never connect Snap Circuits® to the electrical outlets in your home in any way!
Warning: Choking Hazard – Small parts. Not for children under 3 years.
Warning: Always check your wiring before turning on a circuit. Never leave a circuit unattended while the batteries are installed. Never connect
additional batteries or other power sources to your circuits. Discard any cracked or broken parts.
Batteries:
• Use only 1.5V AA type, alkaline batteries.
• Insert batteries with correct polarity.
• Do not mix old and new batteries.
• Remove batteries when they are used up.
• Do not short circuit the battery terminals.
• Non-rechargeable batteries should not be recharged.
Rechargeable batteries should only be charged under adult
supervision, and should not be recharged while in the product.
• Do not mix alkaline, standard (carbon-zinc), or rechargeable
(nickel-cadmium) batteries.
• Do not connect batteries or battery holder in parallel.
• Never throw batteries in a fire or
attempt to open its outer casing.
• Batteries are harmful if swallowed,
so keep away from small children.

Digital Signals
Digital waveforms can be used to represent digital
signals (e.g. 0 or 1, true or false), for example
• 0 (false) – represented by 0 Volts
• 1 (true) – represented by a small voltage, e.g. 3 Volts
Example of Digital Waveform representing digital
signals
3V
0V
Digital signals are represented by a “high” state (1) or “true” state consisting of a small voltage
(e.g. 3V) and “low” state (0) or “false” state consisting of 0 Volts
