The Arduino Mega2560 should be viewed as one of Arduino's flagship microcontrollers which spot a whole lot of features and more processing power than more traditional boards like the Uno. The brain of the Meg 2560 is the ATMega 328 which will be discussed as a criterion under technical features. The Arduino Uno vs. The Arduino Mega 2560 Arduino UNO Tutorial 7 - Piezo Beep. In this easy Arduino UNO tutorial, we are going to use a simple Piezo Transducer to create some beeps. Piezo Transducers are similar to speakers in that an applied voltage causes the piezo crystal to move and make a sound. This LED DIMMER is an Arduino Uno based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage.The method of PWM is explained below. Before we get start building a 1 Watt LED Dimmer circuit, first consider a simple circuit as shown in figure below. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560.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. The tutorial above is a quick demonstration of how to convert Hex strings on your computer and send them to an Arduino. The Arduino can use the values to change the brightness of an LED as shown in this tutorial, however you could use it to modify the speed of a motor, or to pass on commands to another module. arduino documentation: PWM with a TLC5940. Example. The TLC5940 is a handy item to have when you run out of PWM ports on the Arduino. It has 16 channels, each individually controllable with 12 bits of resolution (0-4095). In this tutorial we will be using the PCA9685 PWM module, which enabl
