My project is based on a moving fan using dht11DHT11 sensors.I I have used 2 void loops and the IDE is showing an error "exit status 1 redefinition of 'void loop()'"
"exit status 1 redefinition of 'void loop()'"
One doubt:Can Can we use 2 void loops in the code.Please? Please see and identify the errors.
2nd Doubtdoubt:dht DHT; dht DHT; shows error "exit status 1
'dht' does not name a type" for my version of Arduino 1.8.1
