Programming & Electronics for a Noob Like Me

Home Made Weather station with Arduino Home Made Weather station with Arduino Many like me are thirsty for information, have always wanted to self-produce a simple home weather station to monitor the environmental conditions inside the house. Not long ago I decided to interface an Arduino board with the fantastic free IOT platform Thingspeak, so I can check the environmental data of my home at any time and anywhere. In this tutorial we will see how to send values ​​of Temperature, Pressure, Humidity and flame presence of your home to the Thingspeak platform. First things First Creating a free account on Thingspeak.com is simple, go to the address and click on the top right of "Register". Once registered and logged in, just click on the "Channels" drop-down menu at the top and then on "My Channels" When you are on "My Channels" page click on "New Channel" Enter all the necessar...

Control a Relay with Arduino according to the Temperature Control a Relay with Arduino according to the Temperature Sometimes it is necessary to check high voltage equipment (such as appliances, lights, etc.) based on values. Today we will see how to control a Relay, which can turn on other high voltage equipment, via an Arduino card according to the temperature values. For my tutorial I will use a Dallas Ds18b20 temperature sensor but any sensor will be fine by changing the code appropriately. What is needed:  x 1 Ds18b20 temperature sensor.  x 1 Relay Module.  x 1 Arduino Card whatever it is.  Cables for connection. Assembling We connect components in this way: Temp Vcc Sensor --- Arduino 5V Temp GND Sensor --- Arduino GND Temp Data Sensor --- Arduino Pin 2 Relay Vcc --- Arduino 5V GND Relay --- Arduino GND Signal Relay --- Arduino Pin  Source code Conclusions The circuit and the program ...
