PCF8574 [I2C Module] & LCD Display On today article i will show how to set up a I2C communication to manipulate an LCD display.

DHT22 & LCD Shield In this article i will describe to you, how to develop a home weather station using the DHT22 temperature/humidity sensor. The development board used for this experiment will be the Arduino UNO and the measured values will be displayed on LCD Shield board. Please Enjoy !

Experiment nr.02 - GSM Click (Warning Action via SMS) This is an Warning Action via SMS project who are able to send a warning message for a given situation. In this experiment "the given situation" is one button set on RD7. You must to configure the phone number on which the SMS warning will be sent.

Experiment nr.01 - GSM Click (Temperature & Controll via SMS) Program uses GSM module GL865 for sending and receiving SMS. The scenario of this experiment is as follows: User can interrogate the EasyPIC v7 development board via SMS, and receive the status situation of the motherboard. Port RD0 and RD1 are used to control two Fans and port RA0 is used to measure the temperature of LM35 sensor.

Real Time Clock [DS1307 with Set Functions] & DS18B20 In this article we will talk about DS1307, created by the Maxim company. This IC (Integrated Circuit) could help as, when we want to know what time is it. Interesting fact is that we have added a set functions to this clock. At the core of this experiment, will be the PIC16F876A.

Distance Sensor Sharp 2YOA21 & LCD In the current article I intend to display the measured distance, between sensor and some object, on the LCD with 2x16 characters. If I succeeded or not, you will find only if you will hit the above link in this section.

Dot Matrix Led 8x8 & MAX 7219 In this article we will discuss about functions of MAX 7219, created by the Maxim company. This IC (Integrated Circuit) could help as, when we whant to work with digits and LEDs. At the core of this experiment, will be the PIC16F876A.
