Micro:bit Safety Warnings

Where should you keep your micro:bit when not in use?

• In the anti-static bag

• In your pocket

• In a drawer

• On a metal surface

Answer explanation

The BBC micro should be kept in the anti-static bag when not in use to protect it from static electricity, which can damage electronic components. Other options like pockets or metal surfaces do not provide adequate protection.

Why should you handle your micro:bit by its edges?

• To minimize the risk of damage through electrostatic discharge

• To make it look cool

• To keep it clean

• To avoid fingerprints

Answer explanation

Handling your BBC micro by its edges minimizes the risk of damage through electrostatic discharge, which can harm sensitive electronic components. This practice helps ensure the longevity and functionality of the device.

Which power source should you use to power your micro:bit?

• The provided battery pack or USB lead

• A portable battery charger

• Any USB port

• Solar charger

Answer explanation

The provided battery pack or USB lead is the recommended power source for your micro, ensuring compatibility and optimal performance. Other options may not provide the necessary power or stability.

What should you do if your micro:bit develops a fault?

• Talk with Mr. Quintero

• Continue using it

• Try to fix it yourself

• Throw it away

Answer explanation

If your micro develops a fault, the best course of action is to talk with Mr. Quintero. He can provide guidance or assistance, ensuring the issue is addressed properly rather than risking further damage.

What should you do if the battery in your micro:bit runs out?

• Replace it with a new battery of the same type

• Recharge the non-rechargeable batteries

• Use any random battery you find

• Shake the battery to make it work again

Answer explanation

If the battery in your micro runs out, the correct action is to replace it with a new battery of the same type. This ensures compatibility and proper functioning, unlike using random batteries or attempting to recharge non-rechargeable ones.

Where should you avoid storing or using your micro:bit ?

• In extremely hot or cold environments

• In a well-ventilated room

• In a dry place

• In a classroom

Answer explanation

You should avoid storing or using your BBC micro in extremely hot or cold environments, as these conditions can damage the device and affect its performance.

What could happen if you place metal objects across the printed circuits on the board?

• It can cause a short circuit and damage the micro

• It makes the micro faster

• It cleans the board

• It protects the micro

Answer explanation

Placing metal objects across printed circuits can create unintended connections, leading to a short circuit. This can cause excessive current flow, potentially damaging the microcontroller and other components on the board.

Why should you avoid using your micro:bit in water or with wet hands?

• It can damage the micro

• It makes it run faster

• It improves the signal

• It will clean the board

Answer explanation

Using your BBC micro in water or with wet hands can cause electrical damage, leading to malfunction or permanent damage. Therefore, it's crucial to keep it dry to ensure its proper functioning.

What is a safety rule when your micro:bit is plugged into a computer or any other device?

• Don’t leave it unsupervised

• Don’t touch it

• Don’t turn off the computer

• Don’t use it for more than 10 minutes

Answer explanation

The correct safety rule is 'Don’t leave it unsupervised' because leaving a micro plugged in without supervision can lead to overheating or other hazards. Always monitor devices to ensure safe operation.

Why should you avoid handling the circuit board while plugged into a power supply?

• It could cause electrical shock

• It improves performance

• It changes the code

• It drains the battery faster

Answer explanation

Handling the circuit board while plugged into a power supply can lead to electrical shock, which poses a serious safety risk. It's crucial to ensure the device is powered off before touching any internal components.
