+# send To Screen
+
+Direct the console output to go to the @boardname@ screen.
+
+```sig
+console.sendToScreen();
+```
+
+A "console" is a place for a user to see special messages from a device. It could be  something connected to a serial port, a display that shows text, or even a text file. A console is typically used as a place to send information that is added to a message _log_ (a record of messages that are sent from a device). Your program can send log messages using the [console](/reference/console) functions. The MakeCode editor has a console view that lets you see the console output when your program runs in the simulator.
+
+On the @boardname@, the screen can serve as a console too and you can make your console output go there. Before using the console log functions, set the screen as the console output location.
+
+## Example
+
+Direct the console output to go to the screen. Show 20 values on the screen. Use the up and down buttons to scroll through the values.
+
+```blocks
+console.sendToScreen()
+for (let index = 0; index <= 20; index++) {
+    console.logValue("index", index)
+}
+```
