I want to connect arduino and sonar directly.
red : 5V
as per the github manual.
However, it is displayed on the serial screen as follows.
Ping device failed to initialize!
Are the Ping rx/tx wired correctly?
Ping rx is the green wire, and should be connected to Arduino pin 10 (Arduino tx)
Ping tx is the white wire, and should be connected to Arduino pin 9 (Arduino rx)
I do not know why tx and rx are not recognized.
Please teach me.
The source used is ping 1d-simple.ino.
