I bought a 16 channel Relay Module Smart. As i have read, the relay board can be connect to the Raspberry pi directly.
I using Wiring-pi library to control GPIO Pins. However, when i configure the pins as output, the relay is triggered.
code : > gpio mode 0 out // Relay switched
Is this normal??
When i run these two other commands nothing happens.:
*> gpio write 0 0 // nothing happend
*> gpio write 0 1 // nothing happend
Any advise will be apprecited
