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 ...

Build a DIY IR Remote Controlled Arduino Lego Car Build a DIY IR Remote Controlled Arduino Lego Car Who has never dreamed of an Auto RC or better yet build one? With an old Lego set found in my junk, I've been trying, in recent days, to create a small RC car controlled by a IR remote control. The result will not be the the best performance because the remote control is not a good solution for long distances, as reception can be disturbed may not respond properly to commands. What do we need? Ingredients: Arduino Nano o UNO x1 Stepper motor x1 Servo Motor  x1 IR receiver module + Remote A lego Set with at least 3 wheels Assembling Let's connect all the modules to the Arduino in the following way:  Servo Vcc  ---  Arduino 5V  Servo GND ---  Arduino GND  Servo Data  ---  Arduino D5 Stepper Driver Vcc  ---  Arduino 5V   Stepper Driver GND --- Arduino GND  Steppe...
