Bargraph with voltage
lockandload 2012-09-12 11:39:15 6207 Views3 Replies Hi guys
Im starting to experiment with the arduino and use the uno with an 16x2 (i2c dfr0063) Display.
Now i messure the voltage with an Poti at A(o).
This part run.
And Show the Digital number 0- 1023 on the 1 line left Corner and the Voltage on the right 0-5V.
Now the problem:
On 2nd line i want an Bargraph. Does it Work with this Display?
I search a lot online and found nothing.
There a no draw graph commands at the librarie.
Does anybody can halp ?
So my English is not best sorry

2012-09-13 18:35:05 Hi Lockandload,
There is a sample code included with the library for this LCD. The name is "CustomChars.PDE" this sample code demonstrates how you would define your own custom characters. You should be able to modify this code to include a character which has all the pixels activated.
Being a beginner means you need to read. ALOT! There is lots of help out on the internet and here on the forum. You just need to do a little research. I have pointed you to a resource to get you started. Hector

But i startet use the Arduino. So i dont know how to use that toutorial on on an i2c Display.
Because they use a normal one.
Is there no other chance?
with an other librarie or so because i have to use this Display

it wont be a "bar graph" function. But you can simulate it by lighting up all of the pixels for each character block. OR you could just use asterisks as an alternative...
Here is a tutorial for creating your own LCD characters.
