The module works well when I use the hookup guide and I2C, but I am having a tough time programming it with FTDI. I double-checked the orientation and the soldering, but I get a sync error like when I used the reset pin for I/O once. Any ideas on how to bypass this error? I could try tying reset low when I program it, but I don&rsquo;t want to potentially harm the chip.</p> Customer #586931 urn:uuid:91f2f24d-066b-4b21-89b2-e5d3d13e76cc 2014-09-19T15:40:02-06:00 <p>This guy is a little tough to see in a brightly lit room or daylight. If you need a display for that environment, I would suggest getting a different color. I know the blue one is easy to see in daylight. Otherwise, this dude is pretty cool.</p> Julian4 urn:uuid:c2190475-14c9-91a5-f6ba-51a45cba57b1 2014-08-02T19:38:32-06:00 <p>Mind you that if you want to use I2C with this on a breadboard you won&rsquo;t be able to since the SCL and SDA pins are perpendicular to the VCC and GND pins. This makes them &ldquo;share&rdquo; the same rail on the breadboard. I understand that this makes daisy chaining is easier but I wish they hadn&rsquo;t designed it like this.</p> Zio urn:uuid:ae8df1a1-b233-46fc-6d6b-a8c62d01ddb8 2014-05-29T10:33:35-06:00 <p>Could the sketch be made to fit on an ATtiny?</p> profor urn:uuid:3352b0b9-7571-8c33-ee45-bb97196ea502 2014-05-08T13:17:53-06:00 <p>I ordered this one as my second 7Segment. Before i ordered yellow one which is fine, but i wanted white. But i am very disapointed with brightness, it is so weak so You cant see it on sunlight as i can see it on yellow one. Brightness is set to 250, so this is not the case.</p> <p>Anyway, i am satisfied, easy to use display, works like charm, small size which i need as a clock.

Would it be possible to use its i2c to read an RTC?</p> Alexander Riccio urn:uuid:4e1c4267-a90c-1e06-70e4-32c03e82db05 2013-06-18T01:45:51-06:00 <p>Whoa @ the clock that plays life!</p> Sneak85 urn:uuid:70347908-a5da-0ae7-0ee5-07c7dd4176b9 2012-12-09T13:28:05-07:00 <p>Same thing as the Phillips AmbientLED and L Prize bulbs. The difference between the orange and yellow casing in those two bulbs is the L Prize bulb has some red LED&rsquo;s to help with color and energy.</p> stcarlso urn:uuid:bcb2b978-0916-f509-f90b-77840bc78755 2012-12-07T18:52:17-07:00 <p>I never thought of that. Just grabbed a sample of regular round white LEDs and can&rsquo;t seem to notice the yellow color - is it coating that little dimple in the center?</p> Nick Poole urn:uuid:d690e41c-004e-33f4-67f2-d4577cf722db 2012-12-07T15:07:18-07:00 <p>Yup, #144668 has it right. They look yellow when they&rsquo;re off because you&rsquo;re seeing the color filter. When they&rsquo;re lit, they shine white.</p> Customer #144668 urn:uuid:fc71dc2d-49c8-0a37-fa69-bcb6ac350659 2012-12-07T14:34:42-07:00 <p>That&rsquo;s how white LEDs work. They&rsquo;re a UV LED with a yellow phosphor coating. Look at any white LED carefully and you&rsquo;ll see the yellow. When it turns on, the UV stimulates the phosphor and it makes white!</p> Mike66 urn:uuid:287d453f-59e4-3da0-ba91-f859d56907a4 2012-12-07T12:25:17-07:00 <p>I did not make a thermometer but I did make a clock.
