In this tutorial, we will learn how to measure voltage using Arduino and display the results on an #OLED screen. We will be using an #LM317T adjustable voltage regulator, a potentiometer, a ceramic capacitor, an electrolytic capacitor, a 220 ohm resistor, and an OLED display.
The LM317T will be used to regulate the input voltage, which will be read by the Arduino at A0. The output voltage will be calculated using the formula Vout = Vin * (1 + (R2 / R1)), where R1 is the 220 ohm resistor and R2 is the potentiometer. The output voltage will be displayed on the OLED screen using the Adafruit_SSD1306 library. #arduino #voltageregulator
