-Use the three backticks to separate code.
+## Individual assignment
 
-```
-// the setup function runs once when you press reset or power the board
-void setup() {
-  // initialize digital pin LED_BUILTIN as an output.
-  pinMode(LED_BUILTIN, OUTPUT);
-}
+> measure something: add a sensor to a microcontroller board  
+> that you have designed and read it
 
-// the loop function runs over and over again forever
-void loop() {
-  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
-  delay(1000);                       // wait for a second
-  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
-  delay(1000);                       // wait for a second
