This post shows how to make a real time clock using PIC12F1822 microcontroller and DS3231 RTC chip (or DS1307 RTC) where time and date are displayed on 16×2 LCD. The DS3231 as well as the 16×2 LCD are connected to […]

This topic shows an example for connecting LCDs (with HD44780 or complaint controller) with Microchip PIC12F1822 8-bit microcontroller, this microcontroller has only 8 pins of which 5 can be used as outputs, therefore an I2C LCD is required. An I2C

Interfacing LCD displays with a PIC microcontroller using CCS C compiler needs at least 7 data pins (using the built-in LCD driver). Number of pins needed for the LCD can be reduced to 2 by using an I2C I/O (Input/Output)
In the last ESP8266 project, I built a simple real time clock using a real time clock chip (DS3231 and DS1307), I used a 16×2 LCD to display time and date and 2 push buttons to set them. Now, in
This post shows how to build a real time clock using ESP8266 (ESP-01) module, DS3231 RTC or DS1307 RTC and 16×2 LCD. Time and date are displayed on the 16×2 LCD screen and they (time and date) can be set

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
