In this blog there are many topics talk about the DHT11 and DHT22 sensors and how to use them with different types of microcontrollers including the Arduino. This topic shows how use the DHT11 and the DHT22 relative humidity and […]
The ESP8266 ESP-01 module has 8 pins only of which 4 can be used as I/O (input/output) pins (GPIO0, GPIO2, RX and TX), this number of I/O pins is not enough to run a 16×2 LCD screen which requires at
This post shows a quick guide to program ESP8266 WiFi module with Arduino UNO board and how to use Arduino IDE software in order to write codes for this module. The ESP8266 board contain the microcontroller ESP8266EX (32-bit microcontroller) from Espressif

Generally to be able to use an LCD display we need at least 6 free pins, but the number of pins can be minimized with the help of external components like PCF8574 (or PCF8574A) I2C I/O expander, that’s allows us
There are different ways to build an Arduino based real time clock, one of the ways is using a real time clock chip (like: DS1302, DS1307, DS3231 …) and another way is by using a GPS module. The GPS based
This post shows how to connect the Arduino with GPS module in order to receive data from satellites where the GPS module used in this project is u-blox NEO-6M (other modules also should work). With the NEO-6M GPS module we
In the last post I built an Arduino based real time clock using DS1307 RTC and SSD1306 OLED and in this project I’m going to show how to build a real time clock with temperature monitor using Arduino, DS3231 RTC

This topic shows how to interface Arduino UNO board with SSD1306 OLED display (128×64 pixel). The SSD1306 is a monochrome display which means it has only one color (white, blue, yellow …). Also we’ll show how to simulate the SSD1306
