assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: • A good quality soldering iron (25-40W) with a small tip. • Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections.

Leds and how to use them Leds feature a specific voltage drop, depending on type and colour. Check the datasheet for exact voltage drop and rated current ! Never connect leds in parallel How to Calculate the series resistor: Example: operate a red led (1.7V) on a 9Vdc source. Required led current for full brightness: 5mA (this can be found in the datasheet of the led) Supply voltage (V) - led voltage (V) = series resistance (ohms) required current (A) closest value : use a 1k5 resistor 9V - 1.7V 0.
