Seven Segments of Pi Assembly Instructions
Fit and Solder R1-7
This is the Seven Segments of Pi Printed Circuit
Board (PCB).
R1-7 are 220 ohm Resistors marked with coloured
bands RED, RED, BROWN, GOLD.
(See “Understanding the Electronics” for a
description of the Resistor colour coding scheme
and an explanation of the function of these resistors
and other components). Resistors can be fitted either
way round but fitting them all the same way makes
it look neater! Once soldered crop the leads using
your Wire Cutters so that no more than about 2mm
protrudes on the underside.
Fit and Solder R8-10
R8 is a 470 ohm Resistors marked with coloured
bands YELLOW, PURPLE, BROWN, GOLD.
R9 & R10 are 4k7 ohm Resistors marked with
coloured bands YELLOW, PURPLE, RED, GOLD.
Fit and Solder D1
All components are fitted on this top surface and
soldered on the underside. To assemble the kit you
will need the following:
• Soldering Iron
• Solder
• Wire Cutters
• Small Pliers
D1 is a Zener Diode which MUST BE FITTED
WITH ITS BLACK BAND AT THE TOP as
indicated by the white band on the silk screen
Fit and Solder C1-2
To ease assembly, fit and solder the smallest
components first, followed by the next tallest and
so on. The Resistors and Capacitors can be fitted
either way round but P1,U1,LED1,D1 and SW1
MUST BE FITTED AS SHOWN !!!
C1 & C2 are 100nF Capacitors and can be fitted
either way round
