Task:
Imagine you are designing a system to control the temperature of a room using a heater.
1. Describe a simple algorithm (step-by-step instructions) that could be used to maintain a desired temperature in the room.
2. Explain how this algorithm could be implemented using a microcontroller and a temperature sensor.
**1. Algorithm:** a. Read the current room temperature using the temperature sensor. b. Compare the current temperature to the desired temperature. c. If the current temperature is lower than the desired temperature: i. Turn on the heater. d. If the current temperature is higher than the desired temperature: i. Turn off the heater. e. Repeat steps a-d continuously. **2. Implementation:** The microcontroller would have a program implementing the algorithm: * The microcontroller reads the temperature sensor data. * It compares the sensor data to the desired temperature value stored in memory. * The microcontroller then controls a relay connected to the heater. * If the temperature is lower, the relay closes, turning on the heater. * If the temperature is higher, the relay opens, turning off the heater. This process is repeated continuously, allowing the system to maintain the desired room temperature within a certain range.
