INSERTING ICs
Next don’t forget to place
ICs
into the sockets (1x
TL072
, 1x
MCP4921
, 1x
MCP6002
, 3x
CD4051BE
,
4x
74HC595
, 1x
Atmega
).
There is a notch on each IC that should match with the notch on the
socket (for TL072 is relevant the dot on it).
Installing ICs can be also a little tricky. You should bend
the IC leads in slightly with your fingers. Then press all the leads into the sockets in one shot.
PREPARING FEMALE HEADERS
As you can see
two female pinheaders left
. You can prepare them now. Use your flush cutters to
get the lengths of
19 and 29 pins.
You will always lose one pin when cutting the female headers, so
be sure to cut it always after the last required pin - see the picture to check where to cut to get 19 pin.
Then you have to adjust the 29 pin one by pulling out some pins. See the photos again. Hold on with
these parts then. You will use them in later steps
