Linking two 4511's to drive two independent seven digits displays
If I understand you correctly, you want to use the 4511s to drive two 7-segment displays with the least number of pins possible.
I would maybe use a shift register like the SN74ALS164A, so you can us …

How to connect this 7 segment LED display to Arduino?
The clock and data pins are for your serial input. These can be controlled directly from the Arduino, just connect each to a digital out.
For the data routine, according to the datasheet there is o …

There's no need to apologise for asking any question at all, that's what the site is here for :-)
Okay, about the laser display - it would be possible to have a laser project numbers onto a flat su …

7 segment LCD works on breadboard, not on stripboard
As Olin says, you obviously have a bug which needs diagnosis.
Intermittent issues are a bit more of a pain than simple "not working" issues, but the general procedure is much the same:
Check resist …

Do I need to solder on my DE2 board to replace a broken segment?
If the faulty display is soldered onto the PCB, then yes, you will have to desolder it and solder the new one in place.
If you have a half decent soldering iron, a desoldering pump and some solder wic …

7-segment output: 4-6V, LCD input: 3-5V. How to convert?
If the LCD is the "wide voltage" version which can handle up to 5V, simply run both the LCD and the positive rail of the ADC from 5V.
If it's the 3V version, then this is probably not a good idea (al …

How do I exchange LCD display with 7-segment LED's?
You could do with an oscilloscope to check the drive signal, but assuming it is just an LCD with no onboard drive IC, then it's likely to be driven with an AC voltage of between something like 50-500H …

Inexpensive Frequency Counter and Display for clock generator
A small micro would do this easily. You can set up a capture compare peripheral to count input pulses and read/clear at a regular interval (e.g. 50ms - use a timer interrupt for this)
Then write resul …
