Arduino based digital scale using multiple LED bar graph controller & small LCD

Closed Posted Apr 29, 2015 Paid on delivery
Closed Paid on delivery

I wish to prototype a project as follows

Using an Arduino (I have access to an UNO currently- however the smallest form arduino possible is ideal due to limited space in project case) to control enough bar graph leds to fill a 20cm long linear line (please pick the bar graph led that suits the I/O requirements- although thinner form factors are ideal for case space!)

I need to be able to control each Led to be on or off along the line of bar graph LEDs to indicate scale markings.

These markings can change up and down the bar graph led by pressing a push button quickly to cycle through the various measurement scales

The small LCD display will display the name of the measurement scale selected by the push button.

I suspect this may require the use of shift registers or multiplexing.

Small LCD around this size- http://www.adafruit.com/products/931

Hello The main question is not size, but quantity of dots on bargraph. It's possible to fill 20 cm by 16 leds - or by 40 tiny SMD leds. Very different design will be used for those cases. And yes, you have reason. More
