learning about schematics and electronic symbols

1. Introduction to Robotics
What are Robots

2. Review
•What is a electrical circuit?
•What are some safety protocols while using
snap?

3. Overview
•What is a schematic?
•Symbols in electrical circuits
•Making your own circuit

4. Definitions
Schematic = An electrical diagram

5. Snapcircuitory
Activity
All the pieces are color-
coded and numbered.
Each circuit has 3 basic
components
• Power Source
• Active Component
• Wire
When building these
“CIRCUIT” each one is a
complete loop

6. Battery
If you have more
lines, its more
battery cells
Power source,
normally voltage is
label

7. Press Switch
Basic press
switch, when
pressed its on,
when let go its off

8. Slide Switch
Turn off stays off
Turns on stays on

9. Motor
M for motor,
and within a
circle

10. Electromagnet
One coil is one
magnet, more than
one coil more than
one magnet, straight
line is iron bar

11. Lamp
Basic lamp,
some have circle
with coil inside

12. LED or Diode
Triangle, telling
you direction, if
arrows pointing
out, then it’s a
special light

13. Snapcircuitory
Activity
Your assignment this week
• Follow the snap circuit
instruction
• Use grid to build circuit
• Working in groups of 3-4
• Goal is to do 2-4 Projects a
week (will be graded)
• Draw schematics you made on
paper and leave in folder
• Leave description
