The time-lapse video are an excellent way to acquire a new time perspective of our environment. One of the most common uses is to observe the growth of plants, creating videos that compress days in just a few seconds. If you want to create your own time-lapse video below we explain how you can do so using a mobile phone Android as an IP camera and a Raspberry PI for storage and further processing of the video.

Test TFT connected to Arduino with the text “Scidle.com”

 If you are thinking of doing a project with Arduino UNO and need to view data without having to show them through a serial or USB port on your computer, you’ll need a small screen or display. Let’s see how to use a TFT 1.8″ by SPI. It is not designed for use with an Arduino UNO so its I/O ports do not work 3.3V but 5V. What it allows is powered at 5V, in fact if we feed it to 3.3V for use with an Arduino Nano or 3V Trinket have to short the JP1 connection to not use the voltage regulator that powers both the TFT as the SD card. In this case we will not use the SD Card, but also works at 3.3V, although explain its use in another entry.

The easiest and popular way to introducing us to the world of microcontrollers is using Arduino. The great advantage over other development platforms is its simplicity and above all the support you have from your community. The fact that it is an open-source project opens up endless possibilities for customization, as you have access to all design, from electronics to software.
