Buzzer /Speaker Headphone

5

DIGITAL INPUT

 Switch / Touchapplication

GND

OR

7

ANALOG INPUT

 Medium (eg: Water, soil, nutrient) acts like variable
resistor

3V

8

Check
condition

Execute /run
either one

IF-ELSE VS IF, IF, IF...

Check this
condition first

Then, check
this condition

11

SERVO MOTOR

 Connect servowires
correctly

Don’t let the pins
touch eachother

12

SERVO MOTOR

 Use 3V rated micro servo motor
 Servo motor shaky or not running smoothly?
1.Check program – eg: make sure that music is not

running at the same time
2.Check pin &connection
3.Change thebatteries

13

CROCODILE CLIPS

 Metal parts tend to touch each other if the
insulator is removed.

 Worst case - micro:bit does not turn on or may
even spoilt!

14

CROCODILE CLIPS

 Don’t touch the other pads – unpredictable
outcomes

15

CROCODILE CLIPS

 Always clips the holes

16

3 PINS ONLY?

 Not enough pins for slightly more complex
projects
