Introduction to sensors4:02
Discover how sensors, as input devices, detect environmental changes and send data to microcontrollers and Arduino boards to drive actions in embedded C projects.
Ultrasonic sensor17:13
Discover how ultrasonic sensors measure distance using a transducer and receiver, powered by five volts on Arduino, with three or four pins, and print results to the serial monitor.
Practice test
Infrared sensor28:26
Temperature sensor20:01
Discover how a temperature sensor works, including analog sensors like LM35 and LM36, and use an Arduino Uno to read via A0 and print to the serial monitor.
Practice test
Force sensor22:10
Explore how a force sensor converts applied force into an electrical signal and drives a response, using a force sensing resistor and Arduino to light a bulb based on pressure.
Photoresistor sensor22:23
Explore how a photoresistor, or ldr, acts as a light dependent resistor; light increases reduce resistance and trigger Arduino controlled motors or LEDs.
Quiz - Force and photoresistor sensors
Gas sensor32:32
Discover how a gas sensor module detects smoke or gas via tin dioxide and resistance changes, then sends signals to an Arduino for alarms or actions.
Quiz
keypad27:55
Explains using a 4x4 matrix keypad with Arduino Uno, wiring eight pins, and detecting keys by row and column to print results for lock-style projects.
LCD screen/panel23:27
Learn how a 16x2 LCD backlit display works, its pinouts, and Arduino wiring with an I2C module, plus using the LiquidCrystal library to display text.
Flex sensor4:44
Explore how a flex sensor bends to change resistance and measure deflection, acting as a goniometer. Review 2.2 and 4.5 inch variants, five-volt operation, and medical, gaming, robotics applications.
PIR sensor2:45
Explore how the PIR sensor, a passive infrared motion detector, measures infrared radiation to trigger automatic lighting and safety alarms in rooms, changing rooms, and street lighting.
Soil sensor2:26
Learn how a soil sensor module detects moisture by electrical conduction, with current flowing in wet soil and resistivity rising in dry soil.
