Assembly Instructions
Assembly of the AVRSimon kit should take about 15 to 30 minutes.
The recommended assembly order is as follows, starting with the lowest profile (shortest) components
and building up from there: R1-R6, C1, SW1-SW5, D1-D4, LS1, U1, BT1. For quick reference, this list is
also printed on the back of the AVRSimon circuit board.
Most of the parts are non-polarized, meaning they can be inserted into the circuit board in any
orientation and still function normally. The only exceptions are the microcontroller U1, LEDs D1-D4, and
battery holder BT1, and care must be taken to ensure these components are inserted properly to avoid
potential damage to AVRSimon.
Step 1:
Begin by inserting and soldering the resistors R1-
R6 and capacitor C1. After clipping the leads,
insert and solder the four pushbuttons SW1-SW4
and power switch SW5. The four pushbuttons will
“snap” into the circuit board when they are
properly pushed all the way in.
Step 2:
Next, insert and solder the four LEDs, colored red,
blue, green, and yellow, denoted by D1-D4,
respectively. LEDs are polarized and must be
inserted in the proper orientation in order for
them to work. The flat edge of the plastic LED
casing designates the cathode (sometimes a
notch is used instead) and should be lined up with
the flat side of the LED outline printed on the
circuit board.
Then, insert and solder the piezo buzzer LS1.
Orientation is not crucial, but for aesthetic
reasons you may want to place it so the logo
printed on it appears right-side up.
