Introduction: Arduino Thermometer With Alarm Clock
This is a simple project whith a lot to expand on. I don't have a 3d printer yet but i mesured and created suitable files for use on your 3d printer and also the code.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 2: The Components
For this project you will need:
220 ohm resistor
400 pin Breadboard
An adsong DHT11 humidity and temperature sensor
6 5mm LEDs
a Piezo buzzer
a push button
a 100 k resisto
Step 3: Step 1
conect the pin 1 from the sensor to vcc (5 volts) end the fourth to ground. The second pin should be conected to A1 of the Arduino.
Step 4: Step 2: Creating the Termometer Interface.
place your 7 LEDs and the resistor with jumpers from the digital pins 3 to 9 of the Arduino.
if you have any doubts see the pictures.
Step 5: Adding the Alarm Clock Part:
conect the possitive pin of the buzzer to pin 11 and conect the negative to ground
connect a 100k resistor to ground and to the pin of the buton acordding to the pictures.
the other side of te buton shouol be connected to vcc.
Step 6: The Code:
The code and the 3d printing files are in this section.
