Hi Guys ,
i have a problem with my galileo . i make a project who use Relay module to power AC component like AC Light , Thermoelectric and Water Pump (every component have a power supply ) .
but i got problem when i give power on my galileo and galileo turn on , relay module did not run . i use other component like DHT22 sensor , LDR , moisture and LCD it can run correctly when the galileo on . just relay module who not run.
i have to reupload the program to make it run correctly . i try with other relay module and still got some problem .
anyone have some problem and have fix it ?
please help me ....
sorry for my english
it working correctly . if you use DHT11 you need resistor 10k and also Diode . If you use DHT22 you need 74hc125 and resistor 10k .
for code i use code from example in library . i cant share it over here because too long ( over 400++ lines)
How are you connecting your board to the relay module? Could you please send us a schematic of how you would connect the two? And if possible share with us a picture of the physical connection of both boards.
You mention that the relay module is powered separately from the Galileo, so, I suspect that maybe the circuit might not be properly connected.
