For some reason whenever I code my DHT11 node and link the temp. to the line 1 on the 16x2 display it always shows 0 degrees celsius. Why?
It can be due to incorrect wiring of the sensor. Are you sure you’ve specified the PORT correctly and you have a pull-up 4.7K resistor between the data line and 5V?
Yeah I didn’t put the resistor.
Thanks.
