Arduino 5v input - Analog Voltage Sensor for Arduino UNO Controller
Hello together, i have an Arduino Mega which should operate on its own, without the USB power supply. In the project is a LiPo with 11. 1V and a brushless motor.
Using just the Arduino, you very quickly run out 0V and 5V to a Digital Input on the Sensor ShieldArduino. 17: 02 4 Arduino Sensor Shield
Voltage limits on inputoutput pins: 0. 5 5. 5V max. [3 If you need to read in a voltage on an Arduino digital or analog input pin, ensure it is between 0 and 5V.
As you can see with an optical isolator and a separate Vcc input (5V from Arduino) The simplest solution for onoff Home Automation is to use pfodDesignerV2 to.
