In Part I of this series, we demonstrated how to display analog sensor data (value), such as POT or LM35, on a TFT LCD. A TFT is a thin-film transistor display (typically, a television screen or computer monitor) that’s of much higher quality than a regular LCD display. In this article, we’ll explain how to display…
How to display LDR and soil-moisture sensor values using an OLED
In Part I of this tutorial, we learned how to present data (or values) using a potentiometer (POT) and an organic light-emitting diode (OLED) display. For this project, the POT was an analog sensor (potentiometers can also be digital), which acts as a resistor to control the flow of an electric current. The OLED technology…
