the same range you should get the same brightness from each one. I have used red, orange,
and green, for no particular reason other than to look like a traffic light!!
There are five switches on this board. The GATE and RESET switches are push switches.
These are sometimes designated SPNO (single pole, normally open). Farnell part number:
146-244. You can use momentary toggle types if you prefer. The other three switches are
normal SPDT toggle types. Get good quality ones. Apem and C&K make good ones. There
will be more detail on how to wire the switches to the board later on in this document.
Parts List
The components are grouped into values, the order of the component names is of no particular
consequence. Please read the above section for more details about the parts used in this
module.
A quick note on European part descriptions. R is shorthand for ohm. K is shorthand for kilo-
ohm. For capacitors: 1uF = 1000nF. To prevent loss of the small ‘.’as the decimal point, a
convention of inserting the unit in its place is used. eg. 4R7 is a 4.7 ohm, 4K7 is a 4700 ohm
resistor, 4n7 is a 4.7 nF capacitor.
Resistors
Resistors 1/4W, 5% or better.
