Step 9 -Installing the 4.7k Resistor (Yellow /

Purple / Red):

The 4.7k resistor is part of the “Backup!” behavior

circuit. It doesn’t care which way it’s installed. It’s

marked with the stripes Yellow / Purple / Red.

Bend the leads 90° down

close to the resistor body,

so it goes into the holes

easily.

9A: Bend the 4.7k resistor

(marked yel / pur / red)

leads 90° down

9B: Install the resistor into position “R1”

Step 10 - Transistor Installation:

The transistor works with the resistor as part of the “Backup!” behavior. First take the

transistor and bend the legs 90°towards the flat face. We need to do this so it will sit flat-

face down to the circuit board. It needs to be soldered in face-down in position Q1 so it sits

very flat, to leave space for the battery.

10A: Fold the transistor,

flat-face forward 90°

10B: Install in position Q1

10C: Transistor installed
