Introduction: Arduino Temperature and Humidity on 7 Segment Display
This is a working device i made which displays temperature or humidity respectively by pressing a push button switch.
If the switch is pressed it displays humidity otherwise it displays temperature.
Step 1: INTRO
This device incorporates seven segment displays as output for the value of temperature and humidity to be displayed.
The two seven segment displays works on the principle of multiplexing which saves a lot of I/O pins on Arduino and a lot of coding time.
There is also a switch to choose if you want to view temperature or humidity according to your choice.
Step 2: Items Required
The items required are :-
1. 2 X 7 Segment Displays (COMMON ANODE)
2. 1 X PUSH BUTTON SWITCH
3. 1 X DHT11 Humidity And Temperature Sensor
4. 1 X ARDUINO (UNO,Mega,Nano etc.)
5.1 X Perfboard/BreadBoard
Step 3: Circuit Diagram
Follow the circuit diagram as described in the image.
Step 4: CODE
Upload the code given to your Arduino and your device should work.
