This DIY tool automates LED testing and current limit calculations
Reading Time: 2 minutesGPIO pins on most microcontrollers operate at low voltages, typically between 3.3V and 5V, and are unable to deliver much current — oftentimes stopping at 20-40mA. This is why, when setting up an LED, series resistors are used to limit the amount of current draw and prevent damage to the pin. Mirko Pavleski created…
