Good that you have made progress, though in my initial response I hinted at this, in part;

One thing that I have concerns for is that all this electronics will consume some amount of electrical power which may or may not be significant for your setup. Have you done the calculations in regard to what your capacity is in terms of what you get in with 255 Watts of solar panel and what you will use for all your existing electrical loads, such as lights, radio or laptop?

Under unfavourable conditions when you have low solar gain, will you have enough battery capacity to operate all these modules?

i am going to add battery backup power for the winter. 3 rechargeable 9volt batteries. i was going to use a switch on the panel to switch them on but then i remembered "automation". i will write a code to switch to battery mode by itself.

i also replaced the red/blue leds with red ones and code them to blink every 10seconds to save power.

i stuffed everything into the box and it works but eats allot of juice.

getting crowded on that breadboard so time to find a box. i had an extra one of these from my solar panel kit and gutted it.

everythings working somehow. new update soon

ok, correction: less voltage

thats why my 7 color changer glows bright red when the battery is low. but if i was creating a project and was afraid to kill my battery i would choose red in clear bulb, right?

i found this diagram of wavelength and voltage to share. orange seems like and option too. i dont understand what the X would be in Pink but i bet it eats up your voltage.

i think there must be a capacitor keeping it lit.
what happens when you remove power wire instead of the ground?

9  Using Arduino / Project Guidance / Re: Chicken Coop project, which Arduino to start with? on: March 18, 2013, 11:06:04 pm
if(eggs<1);
digitalWrite(close the door and shut off the lights);
if(eggs>=1);
digitalWrite(RobotChicken, HIGH);

Serial.print(eggs);
10  Using Arduino / Project Guidance / Re: Which Resistors Would You Recommend on: March 18, 2013, 10:41:48 pm
if you put the leds in parallel you would need three 100ohm and one 150ohm i think.
or replace the 150ohm with this to adjust the brightness http://www.ebay.com/itm/250848525880

12  Using Arduino / Project Guidance / Re: Suggestion how to monitor the level of propane/butane gas cylinder on: March 18, 2013, 09:55:18 pm
I think I'd go low tech with a limit switch. On my old gas grill the tank was set a little offset on an edge under the end of the grill with a little wire arm that stuck out the front (in an empty/full slot). A spring was attached to the top of the tank pulling it opposite to the natural full tank tilt to the offset side. As the tank empied the spring would gradually pull the tank back from the heavier offset side, moving the fuel indicater wire back toward the empty side of the slot it was in. The tall tank could be set on a piece of wood with a slightly offset ~ 1/8" dowel under it. The full heavy tank would slightly tilt to the offset side. Instead of a spring on the top of the tank pulling it in the opposite direction, an arm with a weight attached to the top of the tank could probably do the same. When the tank got empty the weighted arm would cause the tank to tilt to the weighted arm side, actuating a limit switch. teeter-totter tank.

but what if you are not home? go high tech dude.

i almost have my propane tank sketch done. im still waiting for china to send my parts. look thru my past posts and find the thread.
