Hi! I’m trying to use the VMA412 to do a graph of the distance received by the ultrasonic controller. When I upload the Arduino program I can see the graph, but the ultrasonic sensor sends 0.00 cm all the time so the graph only draws a line at 0. My question is if there is any library available to m…

#define LCD_RESET A4 // Can alternately just connect to Arduino's reset pin
#define trigPin SCL

SCL and A4 are the same pin.
