VMA309 4. What is Arduino® Arduino® is an open-source prototyping platform based in easy-to-use hardware and software. Arduino® boards are able to read inputs – light-on sensor, a finger on a button or a Twitter message – and turn it into an output – activating of a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board.
VMA309 This example shows you the digital pin function. Connect pin 12 from Arduino® to an LED, and connect this module as above. Update the code. Turn the variable resistor until LED12 turns off. Now, you can make a sound and you will see LED12 turn on. 6.2 Example 2 V.
VMA309 This example show the analogue pin connection. Connect the module as above and upload the code. Open the serial monitor. You will see a number displayed, from 0 to 1023. Make some noise to see the number changing. 6.3 Example 3 In this example, we try to combine the digital and analogue pin in order to control two LEDs. Connect as above. V.
