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
In the previous post I’ve connected the DS18B20 temperature sensor with PIC18F4550 microcontroller in order to measure the ambient temperature, a 16×2 LCD was used to display the measured temperature. Now I’m going to add an SD card for storing

This post shows how to measure the ambient temperature using PIC18F4550 microcontroller, DS18B20 digital temperature sensor where the measured temperature is displayed on 16×2 LCD screen. The compiler used in this project is CCS C (PIC C). Also a small
In the last project I made a simple light dimmer using Arduino where the intensity of light (lamp brightness) is controlled with a potentiometer, now in this project I’m going to show how to add a remote control to the
It is very easy to build a good and simple AC light dimmer using Arduino, this light dimmer is used to control the brightness of a simple 220V AC lamp. In this project I used the LM393 integrated circuit (dual
