Good evening
I am trying to create an LED single line bar graph t. Similar to a vu meter that can count between 1 and 50. The idea is for a button to be pressed each time a count is to be added and one extra LED will illuminate. So for example 3 leds will be lit for 3 counts press button...
Hi All
I am looking at making some fairy lights. Other half wants to do some Xmas bauble project which require lighting up.
I am looking at using these sort of micro rice lights...
Thanks for the reply.
~I thought that the question was unanswerable. I am pretty sure I haven't misread the question. I have copied it below for you to see,

Morning All
I am trying to complete a task sheet on parallel resistors. I have a table and I have to fill in the blanks
All I am given is a value for the first resistor and the total resistance. The question is to find the value of the other two resistors. How do I do this without know knowing...
I can't see who makes them, it doesn't say. Hopefully they will all be from the same batch. I was thinking of buying a breadboard so i can experiment with it a bit and see what works before soldering it all together.
Hi Adam thanks for your reply, that does make a lot of sense. I should have realised that volt drop is dependant of current as V= IR
I haven't got a data sheet all I know is they are 3 volt white 10mm LED's. they are on ebay and don''t have any other information.
Looking around the general...
Hi guys I am new on here and want to clear something up that is confusing me.
I have never done electronics before so I apologise if this question seems stupid. I need to connect 5 LED's in series.
I am planning on using LED's that are 3 volt. Am I right in thinking I will need at least a 15V...
