I have connected D0 as 'trigger' and D1 as 'echo'. I have a label1. I have a 'Button1' and when i press this, i have written:
Private Sub Button1 click Dim distance as integer dist= EzB.Connect2.EZB.HC_SR04.GetValue(Digital.DigitalPortEnum.D0, Digital.DigitalPortEnum.D1) label1.text=dist End sub
No distance is reported in label1 when i press the button. Where am i wronging?
The result is always "20".
