QUESTION
I am having a hard time getting the input from an ultrasonic range finder to display the distance on an Oled display. I am using an Arduino Nano. I can get the display to print Hello World while I can view on the Arduino IDE serial monitor all of the inputs from the range finder. I am using a 1.3 inch oled display and a 3 pin ultrasonic range finder. It has the vcc, ground, and signal pin. I have tried many different combinations to try and make it display but nothing is working. Here is what I have currently that at least makes both devices work at the same time. For the display and sensor the manufactures provided codes to make them work independently on the Arduino Nano. Sorry for all of the confusion with my code.

Answered 2019-Oct-16 at 08:13I can't try this out, but my guess is that you have to convert the range from the ultrasnoic sensor to a string, by using String()
and then you can draw that on the OLED display. If you declare your variables outside the loop function you can use them in the draw function as well.
QUESTION
While using U8glib I'm trying to pass a value to the draw function but can't get it to work. Always get an error in line "lcd_1.drawStr( 0, 10, sms);" no matching function for call to 'U8GLIB_SSD1306_128X32::drawStr(int, int, String&)' Is it even possible to do, to use a variable on "lcd_1.drawStr( 0, 10, sms);" ? Tryed the same thing using Adafruit lib and it works. Thanks
