Project Builder - LED Barometer

Question

Hi 
 I'm looking to find someone in the UK, ideally the London area, to discuss the possibility of building an LED barometer that I have visually designed. I have a clear understanding of what I would like from the design and have an appreciation of electronics and principles, though lack the practical skills/programming knowledge - if anyone would be intersted in discussing/exploring, I would welcome your response. Thanks, Spencer

From your detailed description in your reply to electronicbiker I think your best bet would be to use a string of neopixels controlled by an arduino . You will need a pressure sensor as well. 
 The neopixels are cheap and will allow you to have any colour for any LED and pretty much as many as you like. 
 Arduinos are good for simple projects with a lot of support on the web. You could make your own control board or use one of dozens of alternatives if you don't fancy the Arduino. 
 If you want to go wild you could have a column display of pressure a bit like a zoomed in mercury barometer.

 You can buy neopixels from Aliexpress very cheaply - either loose (requiring assembly onto a pcb) or on tape (ready to connect to a microcontroller.).

Perhaps this Arduino project is something similar to what you are trying to do ?

 Also perhaps take a look at Natasha's series here on how to animate NeoPixel LEDs with a micro:bit
