left arrow blinks. This gives them hands-on experience with how sensors detect
movement and how these movements are converted into programmed actions.

you will observe how quickly and accurately
the micro:bit responds to changes in direction

and how the LED display adapts.

Application

Fitness Trackers: These devices use
accelerometers to track movements, such as

steps, running, or other physical activities,
helping users monitor their health.

Building a Touch Sensor

Micro:bit has various sensors; Touch Touch Sensor

sensor is one of them that help us to
make innovative projects. This project
will light up the LED display with a

heart icon pressed, but only as long
as you hold your finger on the logo

on the front of new micro:bit. By this
project we can make an automatic
light system.

A touch sensor primarily works when

an object or individual gets in physical
contact with it. Touch sensors are also called as tactile sensors and are sensitive
to touch, force or pressure. It can be implemented using Capacitive or Resistive

sensing technology.

• The gold logo is a touch sensor that works a bit like a touch screen on a mobile
phone, measuring tiny changes in electricity. This is also called a capacitive
touch sensor, because it uses measurements of electrical capacitance to

work.

• The ‘on logo touched’ block is triggered when you first touch the logo.
• The ‘on logo released’ block senses when you let go of the logo and the

program clears the display.
