An image slideshow with an Arduino and a tft display with a sd card module

In this tutorial we use our Arduino to show an image slideshow on a 1.8 inch tft module with SD card support (HY-1.8 SPI). We will change the size and the format of the images and copy them to the SD card. After that the Arduino loads them from the card and shows them on the display.

Simple indoor climate monitoring with an Arduino, BMP085, DHT11 and a RTC

In this a bit more extensive project we deal with several factors on the subject of indoor climate. We will measure the temperature, humidity and air pressure, saving maximum and minimum values of our measurements and show it on a TFT display.

A 1.8 inch TFT color display (HY-1.8 SPI) and an Arduino

To give our Arduino the chance to tell sometimes what’s actually going on and do not always use the serial monitor, it is time to buy him a small display. Fortunately, there is a wide range of available shields and breakout boards. In this case, we use a 1.8 inch TFT color display with 128×160 pixels (HY-1.8 SPI, the name on the board), equipped with an SPI interface, which gives us the opportunity compared to displays with parallel interface, to have more free ports for other applications available.

The HC-SR04 ultrasonic distance sensor and an Arduino

Learning from nature can also be used in electronics. Today we use the capabilities of the bat around with the HC-SR04 distance sensor to detect obstacles or measure the distance of an object using ultrasonic waves.

Nokia 5110 LCD, an Arduino Pro Mini 3.3V with 8MHz clock frequency

As a quasi-nostalgic relic of an almost extinct generation of cell phones we use today, the Nokia 5110 LCD screen from the cellular phone with the same name, kindly as a breakout board for a small budget. Because the display operates at 3.3V, we use it together with a 8MHz clocked Arduino Pro Mini, which also runs at 3.3V.
