For example, if resistors are used to halve the input voltage then the Arduino can effectively read up to 10V (since 10V will be read as 5V, 5V will be read as 2. The Arduino Due has a number of facilities for communicating with a computer, another Arduino or other microcontrollers, and different devices like phones, tablets, cameras and so on. This module lets you interface your Arduino/Raspberry Pi or any other micro controller with Industrial Sensors and Devices with a 4-20mA output. Lastly, we can input V 2 into the equation as a variable which is read from one of the analog pins. If we supply the AREF Pin with 3. 3V to any I/O pin could damage the board. it seems to be quite faulty. The recommended range is 7 to 12 volts. MQ-2 Smoke Sensor Circuit Built with an Arduino. The power pins are as follows: • VIN. The analog Read function is the output of the 10-bit ADC on the Arduino. By default, the acceleration range is set to +/- 1.
