 ### Blink the LED
 
 - **Step 1.** Copy the below code to Arduino IDE
 
+Make sure your `D10` is connected to an LED as shown in the diagram above.
+
 ```cpp
+
 // define led according to pin diagram in article
-int led = D10;
-// Blink the onboard charge led
-// int led = LED_BUILTIN;
+const int led = D10; // there is no LED_BUILTIN available for the XIAO ESP32C3.
 
 void setup() {
   // initialize digital pin led as an output
