ELECTRONIC KIT — SELECTION AND FIRST-BUILD RECORD
Choose one learning goal, then use the instructions for the exact kit and board. This record
is not a substitute wiring diagram.
Learner / date / goal:
Kit style: snap / breadboard / solder / programmable
Exact kit and board revision / manual URL and version:
Age guidance / supervision / small-part and tool requirements:
Included controller / data cable / power source / spare parts:
Computer OS / required software / offline instructions available:
First exercise / expected observable result:
Parts and values / LED polarity reference:
Supply range (V) / resistor (ohms) / assumed LED forward drop (V):
Prediction: current = (supply V - LED drop V) / resistor ohms
Illustrative only: (5.0 - 2.0) / 1000 = 0.003 A = 3 mA; resistor power = 0.009 W.
Power disconnected: nodes checked / split rails checked / polarity checked:
Result with documented power / photo filename:
One change permitted by lesson / predicted effect:
Observed effect / explanation:
Troubleshooting: symptom / single change / result:
Unexpected heat or odor: disconnect and investigate before retrying.
Use the meter's correct function and connections; never connect current mode directly across
the supply.
Next exercise and the one new concept it introduces:
