DOs and DON’Ts of Building Circuits
-13-
After building the circuits given in this booklet, you may wish to experiment on your own. Use the projects in this booklet
as a guide, as many important design concepts are introduced throughout them. Every circuit will include a power
source (the batteries), a resistance (which might be an LED, lamp, motor, integrated circuit, etc.), and wiring paths
between them and back. You must be careful not to create “short circuits” (very low-resistance paths across
the batteries, see examples below) as this will damage components and/or quickly drain your batteries. Only
connect the parts using congurations given in the projects, incorrectly doing so may damage them. E-Blox

is not
responsible for parts damaged due to incorrect wiring.
Here are some important guidelines:
DO USE EYE PROTECTION WHEN EXPERIMENTING ON YOUR OWN.
DO include at least one component that will limit the current through a circuit, such as the speaker, lamp, LED,
integrated circuit (IC, which must be connected properly), or motor.
DO disconnect your batteries immediately and check your wiring if something appears to be getting hot.
DO check your wiring before turning on a circuit.
DO connect the IC using congurations given in the projects or as per the connection descriptions for the part.
DON’T connect to an electrical outlet in your home in any way.
DON’T leave a circuit unattended when it is turned on.
DON’T touch the motor when it is spinning at high speed.
