Good night people My English is not very good, but I think we can talk. I am in need of strength in a project in which I receive several measurements of my 3 ultrasonic sensors HCSR04 with the arduino and the mod. bluetooth HC06, I already delimited with the split space function and I am receiving these measures only that I am unable to do operations with them because it does not come out in the number format, it is as if it showed me a number but the type of the variable would be string or text. objective: I want to transform these measurements into numbers so that I can do mathematical operations as a multiplication, because I will make a bar that is loaded every time an object is very close to the sensor.
what I've done so far is in the figure
the arduino data is being sent by the bluetooth.print () command
