Robotics Sensor Assessment by(Sir JM)

Which type of sensor is best for detecting whether a button is pressed in a robotics project?

• Analog sensor

• Digital sensor

• Temperature sensor

• Light sensor

What is the typical output range of an analog sensor when connected to an ESP32's ADC pin?

• HIGH or LOW

• 0 to 255

• 0 to 4095

• 0 to 1023

Which sensor would you choose for a robot that needs to measure exact temperature variations?

• Push button

• PIR motion sensor

• LM35 temperature sensor

• Limit switch

In the Arduino IDE code for a digital sensor, which function is used to read its state?

• analogRead()

• digitalRead()

• analogWrite()

• Serial.begin()

For a robot that stops at a cliff using on/off detection, which sensor is most appropriate?

• Potentiometer

• LDR (light-dependent resistor)

• Infrared proximity sensor (digital)

• Temperature sensor

What is the purpose of the pinMode() function in an ESP32 program?

• To read sensor values

• To set a pin as input or output

• To start the serial monitor

• To control LED brightness

Which sensor would be best for a robot that adjusts its speed based on ambient light levels?

• Push button

• LDR (light-dependent resistor)

• PIR motion sensor

• Limit switch

In the provided lesson plan code, what does the map() function do in the analog sensor example?

• Reads the sensor value

• Converts the analog value (0-4095) to a range suitable for LED brightness (0-255)

• Sets the pin as an input

• Prints values to the serial monitor

Why is Tinkercad used in this lesson plan?

• To replace physical ESP32 boards

• To simulate circuits and test code virtually

• To write code automatically

• To connect to the internet

What is a key factor in selecting a sensor for a robotics project?

• The color of the sensor

• The design requirements (e.g., accuracy, range, power)

• The weight of the ESP32 board

• The cost of the Arduino IDE
