The best laid plans of mice and men ....
When fitting the tail and indicator LEDs it became obvious that there was = quite a bit of wiring to connect. Much more than appeared at the front end =
of the process. To explain, there were 3 8-LED strips. Each had 2 grounds (= 6), 1 supply (3), 1 Data In (3), and 1 data Out (3). A total of 15 potentia=
l wires to connect and that is only for 3 lights on the rear. Although I co= nnected the grounds (2) there were really too many others, although I conti= nued. Haven't connected the Arduino and switch yet.
A better way, that requires considerable program code change but should be=
possible:
My long strips are also 30 LEDs/metre =E2=80=93 1 metre long and 1.8A calc= ulated maximum current.
=C2=A0
Run a number of controllers off the one pin. I could mount a complete stri=
p around the back end of the trike (in this explanation), centred on the mi= ddle LEDs =E2=80=93 physical number 15 and 16. I could have, maybe, 5 contr= ollers off the one pin, say:
=C2=A0
No. 1 - Controlling only physical LEDs 14, 15, 16 and 17 as a tail light = =E2=80=93 on all the time but flashing, overridden by a solid brake light.
No. 2 - Controlling only physical LEDs 11 to 13 and 18 to 20 as left and r= ight turn indicators.
No. 3 =E2=80=93 Controlling whatever LEDs as hazard flashers.
No. 4 =E2=80=93 Controlling only the indicator LEDs to provide reversing l= ights.
No. 5 =E2=80=93 Controlling all the LEDs in the strip as display lighting = when No. 1, 2, 3 and 4 are not required.
=C2=A0
The above would only require the installation of a single LED strip (conne= ctors already attached). I have a few momentary action pushbutton switches = that could be used with some clever logic applied to lock out that which is=
not required at the time, using self-latching algorhythm for the purpose. =
My earlier switching control was part of self-latching until I changed it. = Will have to change it back again.
=C2=A0
See? Another project suggested before the current one is finished.
Now, back to getting my afternoon's wiring connected to the Arduino. I sho=
uld have working indicators and tail light until I rewrite the code.
