The objective of this post is to describe the main functionalities of the DS3231, a very accurate real time clock from Maxim.
The objective of this short post is to explain how to solve the error opening the awt.dll file, during the installation of the Arduino IDE.
The objective of this post is to show how to connect the DHT11 sensor to an ESP8266 and write a simple program to measure temperature and humidity. We assume the use of the Arduino IDE for programming the ESP8266.
This post lists some components to create a basic electronics prototyping kit, which can be bought for very low prices at eBay.
The objective of this post is to explain the architecture of a simple temperature logger using the ESP8266 and a web server deployed on the cloud.
This post describes one of the basic laws of circuit analysis, more precisely KCL (Kirchhoff’s Current Law), which states that the the sum of the currents leaving and entering a node is zero.
This post describes one of the basic laws of circuit analysis, more precisely KVL (Kirchhoff’s Voltage Law), which states that the sum of all voltages in a closed loop of a circuit are equal to zero.
