Okay, it did not let me to rest, so i've solved the problem. Practically i've shorted the - leg of that led to the +Vcc through a resistor (2k)...
Sorry for this topic again, but i'm a bit disappointed. I'm using the LM3914 in dot mode, and my first led out of ten is always lit a very little...
I got mines for ~$2.3, but five pieces won't make me go bankrupt :)
lm3914n? :hip:
Thanks again, cpemma!
I got a question again. I would like to connect (lets say) LED 3's output to LED 7's output together, and use a single LED for these "values". Do...
The simplest detonator i've done (back when i was 10-11 years old), was a single, very thin wire (out of a cord) wrapped around the head of a...
Thanks! Really it has got 3 legs :duh:
Let's say i take a 4.5V battery (i'm currently using one to test my setup), put a 1k pot between the battery and my "voltmeter" and that's all?
cpemma, I already got a cheap digital multimeter (supposed to have max +-1% tolerance). Do you happen to have the schematics of such an...
Of course if you got some "reliable reference voltage supply" to set the circuit up, adjustable pots are the way to go. Sadly i don't have such a...
cpemma, Are my calculations above correct? Could you confirm that? Regarding to 10k resistor chain: how about putting another 10k on the 4th...
:duh: Thanks! I think i do understand now :D I've found some 2k (R1) and 2k32 (R2) resistors in the local shop. That would mean...
Please anybody, enlighten me! :o
Thanks for the link and reply! I do understand how does it set the 1.803v [REFout = 1.25 * (1+R2/R1)] but I couldn't figure it out how the...
Hi! I need some help with the LM3914 LED display driver. I would like to create a simple voltmeter in the range from 1.85V to 2.7V. I've already...
