Differenze tra le versioni di "Arduino Auto Reset: Disable an Enable at run time"

@@ Riga 1: / Riga 1: @@
-Modern Arduinos have a Auto Reset circuit: There is a 0.1uF capacitor between the #DTR (not DTR) pin of the USB/UART chip and the reset pin of the Atmega.
-This circuit resets the Atmega microcontroller each time a new serial connection is established, it is possible in this way to upload new sketches
-at any time. THe new connection resets the microcontroller and then the new firmware can be uploaded.
-The drawback of this circuit is that it is not possible to support services that must ''survive'' new serial connections.
-For example I am designing a Home Automation unit controlling some lights based on Arduino Nano. The lights can be turned on and off using some
-buttons, the state can be queried and changed using a serial connection.
-I have designed the following circuit to Enable and Disable auto-reset using an output pin of the Arduino itself or from another controller.
