What can I use a bar graph for?
The bar graph is perfect for adding visualisation to any monitoring projects you may have, such as humidity, temperature and sound levels (other components required). A small amount of soldering is required.

You are provided with two 12-segment bar graphs, a backpack to solder them to, and header pins to use with breadboards or extension jumpers. You can solder cables in place of the header pins, and there are also mounting holes to allow you to mount the bar graph into your latest and greatest projects.

What Arduino library will I need?
To fully utilise this bar graph you will need the appropriate library to help you along, this is available here. This will allow you to quickly and easily communicate with the bar graph using the simple I2C function.

Rated 5 out of 5 by from Excellent A good way to visualise system behaviour and really easy to configure and use

I need a bar graph display to indicate level of charge on a car battery. Will this do the job and, if so, what else do I need to make it work
