Project 1 2 3 Microcontrollers are used to implement autonomous electronic systems. An example is a fire alarm system that detects a fire and emits an alarm signal for evacuation. Design and implement an electronic circuit with a microcontroller such as micro:bit, that can be used as a fire alarm system. Write the code required for the microcontroller to activate the alarm under specific conditions such as a temperature increase. In addition to indicating with an alarm sound, indicate the danger of fire with a visual signal. Use appropriate symbols or text for hearing-impaired people. 4 Extend your design to check for unsual light intensity levels in the environment. High temperatures and extreme brightness are indicators of a fire inside a building. 5 وزارة التعليم Ministry of Education 2024-1446 Simulate and troubleshoot your circuit design with Tinkercad Circuits. Are you using the minimum electronic components required? It is important to design electronic circuits with the minimum number of components for simplicity, cost efficiency and low power consumption. 227
