Step 1 - 3 x 240 Ohm Resistors (Red / Yellow / Brown):
These resistors are
part of the SP12 programming interface that buffer the signals. Install in positions
R1, R2, & R3.
Building It - Steps 1, 2, 3
The ATMega8L Brainboard
Step 1:
240 ohm resistors
Install at
R1, R2, R3
Step 2 - 1 x 10k Resistor (Brown / Black / Orange):
This 10k resistor is the
signal pull-up for the reset switch. Install it in position
R4
.
Step 2:
10k resistor
Install at R4
Remember - when you’re building this kit, you must bend the resistors down
right near the resistor body. This PCB is designed on the tight side, so being
compact counts!
Steps 1-2
Complete
Step 3:
1k resistors (x5)
Install at
R5, R6, R7, R8, R9
Step 3 complete
Step 3 - 5 x 1k Resistors (Brown / Black / Red):
These 5 resistors are installed
in positions
R5, R6, R7, R8, & R9
. These resistors limit the current going to the
red tiny indicator LEDs (yet to be installed).
Note: If you need extra I/O for other purposes, you can re-use these ports by
leaving these resistors out. Of course, then you have no blinky lights!
