IET Lessons

The IET Collection

This is a series of resources created by the IET (Institution of Engineering and Technology) to support the use of the BBC micro:bit in Design and Technology lessons.

Automatic Lighting

Saving Lighting Energy with the BBC micro:bit

People are always looking for ways to save energy. It is estimated that the average UK homeowner could save up to £240 a year alone on the cost of lighting their home.
In this unit of learning, learners will use the BBC micro:bit to develop a prototype for an LED based automatic home lighting system, designed to save energy.

School Bag Alarm

‘Keep off that bag!’ – BBC micro:bit School Bag Alarm

Schools are busy environments and it is easy for learner’s bags to be left unattended, taken by mistake or even stolen. Alarm systems using embedded electronics and programmable components can be developed to protect the property of learners during the school day.
In this unit of learning, learners will research, program and develop a working school bag alarm system using the BBC micro:bit.

Flood Warning

Using the BBC micro:bit to Create a Flood Warning System

Flooding is becoming increasingly common in parts of the United Kingdom and causes a lot of damage to peoples’ homes. The sooner a potential flood can be detected, the more time homeowners have to prepare and to save their property.
In this unit of learning, learners will identify the design problems presented by flooding. They will then develop a working flood warning system using the BBC micro:bit.

Heart Rate

Personal Health Check – BBC micro:bit Heart Rate Monitor

There are many reasons to monitor heart rate. For example:
  • There are 2.7 million people in the UK currently suffering from heart problems. The quicker these problems can be found and treated the better the chance of a full recovery.
  • Athletes measure their heart rate during training to ensure that they are training in their optimum physical range.
In this unit, learners will use the BBC micro:bit to develop a prototype for a personal heart monitoring system.

Stepometer

Count Those Steps! BBC micro:bit Based Step Counter

Walking is an excellent form of exercise that most people can take part in. The average person walks 3000-4000 steps per day. The National Health Service in the UK has set a challenge for each person to walk 10,000 steps per day. This can be counted using a step counter or stepometer.
In this unit of learning, learners will integrate a BBC micro:bit based programmable system into a complete and commercially viable step counter product, that will aid people taking part in this challenge.

Transport Displays

‘How's the Service, BBC micro:bit?’ - Information Device for London Underground Travellers

The London Underground is one of the busiest public transport systems in the world. It is used for over 1.2 billon journeys a year. Passengers need up to date information when using it so that they can plan their journeys well.
In this unit, learners will use the BBC micro:bit to develop a prototype for a programmable information system for users of the London Underground.

Home Security

Beat the Burglars with a Programmable System

Home security is increasingly important as homeowners look to ensure that their properties and possessions are protected from potential burglary. Alarm systems are being developed with increasingly complex embedded electronics and programmable components.
In this unit, learners will research, program and develop a working door access and alarm system using the BBC micro:bit.

Home Energy

Monitor your Energy Usage with the BBC micro:bit

Reducing energy usage in the home saves money, increases energy security and reduces the need to burn unsustainable fossil fuels. The first step in doing this is monitoring how much energy is used each day.
In this unit of learning, learners will use the BBC micro:bit to develop a prototype for a home energy usage monitoring system that will inform people how long they leave their lights and/or heating on during the day.

Pedestrian Crossing

Improving road safety with the BBC micro:bit

Hundreds of people are killed in accidents on roads in the United Kingdom every year. When schools are situated close to roads there is particular danger to children crossing them. A good, well programmed pedestrian control system can minimise risk and enable people to cross the road safely.
In this unit of learning, learners will use the BBC micro:bit to develop a prototype for a pedestrian crossing for a local secondary school.

Robot Buggy

Use the BBC micro:bit to make a maze-travelling robot

Programmable robotic systems are becoming an important part of industrial developments in Design and Technology. Robots are now being developed that can sense changes in their surroundings and respond accordingly.
In this unit of learning, learners will use the BBC micro:bit to develop a robotic buggy that can successfully navigate a maze or path.

Temperature Monitoring

Cooked to perfection: use the BBC micro:bit as a temperature probe

It is very important that food is prepared or cooked to the correct temperature. Too cold and it could cause food poisoning, too hot and it could burn. A temperature probe can be used to check that the temperature of food is at the right level.
In this unit of learning, learners will use the BBC micro:bit to develop a prototype for a food temperature probe that will warn people when their food is too cold.

Beep Tester

Explore the world of technology in sport with the BBC micro:bit

Technology can be used in sports to enhance performance and help participants to improve their fitness and stamina. For example, automated beep tests can be used to monitor fitness levels during training sessions, and set targets for future improvement.
In this unit of learning, learners will use the BBC micro:bit to develop a prototype for an electronic beep test that can be used to help people monitor and improve their fitness levels.

Score Counter

The million dollar question: can you turn the BBC micro:bit into a score counter?

Some people enjoy taking part in quizzes in their spare time. Keeping an accurate score of points gained by each team, or player, is important when deciding who the overall winner is. Programmable counter systems can be used to do this quickly and easily, and reduce the likelihood of human error.
In this unit of learning, learners will use the BBC micro:bit to develop a programmable counter that can be used to keep score during a quiz.
