I send from another hardware a string to my arduino .
I use arduino uno , connected the rx to the arduino and I get this data .
When I send "5" I get in bytes :
I received: 0
I received: 101
I received: 121
I received: 61
When I get in char then string I get
ey=
Were in bytes if I convert is the same . 101 is e , 121 is y , 61 is =
Post your code
And a diagram of how everything is wired up - a photo of a pencil sketch will be fine.
And a description of the "another hardware" that is sending the data - a link to a datasheet would be great.
