Via the serial interface of an Arduino, you can send and receive data. In this tutorial, I want to explain how to send & evaluate data via the serial communication pins RX & TX to another Arduino. Parts list For this tutorial, I use the following components: Note from me: The links marked with an…
DIY Weather Station v2.0
In this article I would like to introduce you to the DIY Weather Station V2. This slightly improved version now has an OLED display and a piezo buzzer for the output of signals. History – What is the difference to version 1? In the first version, I had chosen the design of the board to…
Arduino Lesson #8 – MAX6675 temperature module
In this post, I like to present the MAX6675 temperature module at Arduino UNO. In the past post at my blog, I show you another digital temperature sensor Arduino Lesson #6 – digital temperature sensor DS18B20, but this sensor is very special. Buy a MAX6675 temperature module You can find this module very cheap at…
Shelly 1 #1 – set up and operate from a power socket
In this post, I want to introduce you to the Shelly and show you how to set it up and create an app-controlled socket. I have already explained in detail how to control a socket using Amazon Alexa in the German article ESP8266 – Alexa gesteuerte Steckdose. Here, however, we will first look at how…
Arduino Lesson #7 – Photoresistor
In this post, I like to show, how to connect and code a Photoresistor at an analog pin on the Arduino. You get the photoresistor as simple electronic part or pre soldered at a tiny pcb. I show you a circuit with both of them. Buy a Photoresistor You can find and buy this tiny…
Arduino Lesson #6 – digital temperature sensor DS18B20
In this post, I like to show how to connect and code a digital temperature sensor DS18B20 at Arduino UNO. I’ve shown you in my last blog post Arduino Lesson #5 – analog temperature sensor LM35DZ an analog temperature sensor. Here you get some information how to connect the digital sensor DS18B20. Required components for…
Arduino Lesson #5 – analog temperature sensor LM35DZ
In this new post at my technic-blog, I like to show, how to read temperature values from an analog LM35DZ device at Arduino UNO. Buy a LM35DZ sensor for Arduino The analog temperature sensor of type LM35DZ is very cheap, and you get this device at ebay.de for €1.7 without shipping cost*. If you want…
Arduino Lesson #4 – programming IR Remote control
In this new post at my technic blog, I like to show you how to code an IR Remote control at Arduino UNO R3. In my last post Arduino Lesson #3 – control tiny servo motor SG90 I show you how to code and control a servo motor. In this post, I want to control…
