Electronic Senses ................................................................. 
Would you like to know if it’s raining outside? All you
have to do is build a weather sensor. In this chapter,
you will discover a lot of other exciting circuits as
well — ones that can differentiate between cold and
warm, or that can even respond to invisible light.
Storing Electricity ................................................................ 
Are there actually components in the circuit that can
store electricity and then provide it again later? Yes,
that’s exactly what capacitors do. Here’s where you
learn all the most important things about how
capacitors work.
Timer Switches, Blinkers, and Off-key Noises ............. 
Your capacitors will have an important role to play in
this chapter too. You can use them to construct an
adjustable time switch, a red-green flasher, and other
useful circuits.
Universal  Timer .......................................................... 
Your electronics kit has another component in store
for you. The  timer will help you assemble
complex circuits with the use of very few components.
Try it!
Amplification Operations ................................................ 
In this chapter, you will learn what you can do with
your operational amplifier — “op-amp” for short. It
can be used for all sorts of devices ranging from a
tool for comparing voltages to a “random generator.”
And if you combine it with the FM module, you can
have a home-made radio alarm right next to your bed.

EXPERIMENTS
Colored Light from Circulating Current .......................... 
Experiment with the bright colors of your three LEDs,
and dive into the basics of electrical current.
Circuits of Sound .................................................................. 
Whether you want to sound like a police car,
ambulance, or fire truck, you can use your sound
module to bring the sounds of all these vehicles right
into your living room, and even switch back and forth
between them whenever you like.
Pockets of Resistance.......................................................... 
Why would you want to install extra resistance in a
circuit? As strange as it might sound, resistors are
very important in electronic circuits. This chapter
explains why.
Sizing Up the Invisible ......................................................... 
It’s time for your voltage and current meter to get into
the action. You can use it to visualize the voltage and
strength of the electrical current flowing through
your assembled circuits.
Digitally Switched ............................................................... 
Switching or amplifying — those are the tasks of
the most important electronic components. With
the help of your transistors, you will even learn
how computers work.
