I am about to have dinner, so instead of typing out the entire response, I copied my comment on another thread on the same topic.

For example pin 10 on the uno can either be used as digital or PWM, whereas pin 10 on the Micro Pro can function as analog, digital or PWM. Sounds like 0V end of your pot isnt connected to Ground. Many pins of the arduino are capable of more than one of those functions, you can check this by looking up 'arduino pinout' for your particular board. The example codes that come with arduino ide, which uses pots, doesnt work with my mega, the one named ReadAnalogVoltage, the output at SerialMonitor is always 5v or 1023. It contains everything needed to support the.

It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. Also can be used to switch on and off another fast component, like a transistor, which in turn will switch on and off a load (say a motor) and thus you can control the rotation speed of said motor. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. XTAL1, XTAL2: Thch anh(16Mhz) c kt ni vi xung clock cung cp cho b iu. This is useful for controlling a varying output, say the brightness of an LED, the position of a servo motor (this is a deeper subject, because the servo motor has a little 'brain' of its own, which translates the incomming PWM into angle of rotation).

It's a clever technique called 'pulse width modulation', where the microcontroller will turn the output ON for a set period of time (duty cycle) and then turn it off for some time.

It's not REALLY a smooth transition and it's not exactly a varying voltage, but rather varying on/off period by quickly switching the output on and off. PWM pins are capable of WRITING a voltage between 0V and +5V. 3x Gravity: analog water pressure sensor. I have a project that has a: Arduino Mega 2560.

This is useful when you want to measure brightness LEVEL (not just light on or off), or read a potentiometer value (for controlling the brightness of an LED for instance) and other similar purposes. Code from Arduino Mega to NodeMCU ESP8266. For the more popular Arduino boards such as the Uno, Mega, Duemilanove. You decide whether they read or write when you declare pinMode() Īnalog pins are capable of READING (this is key) a voltage between 0V and +5V (which is translated into a value between 0 and 255 when you use analogRead() function). In normal analogRead use, the reference voltage is the operating voltage of the board. Long answer - yes, but check pinout diagram for your boardĮssentially the arduino has 3 types of pins (there are more, but for the sake of this thread we'll say 3).ĭigital pins are capable of reading or writing either ON or OFF (let's say 1 or 0, HIGH or LOW, voltage +5V or 0V).
