Arduino Uno Temperature and Humidity

Arduino Uno Temperature and Humidity

The DHT11 is a digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and sends out a digital signal on the data pin (no analog input pins needed). Its simple to use, and the update timing of the sensor is about 2 seconds. Thermistor temperature … Read more

Arduino Uno Super Starter Kit Ultrasonic Sensor

Arduino Uno Super Starter Kit Ultrasonic Sensor

The ultrasonic sensor (HC-SR04) is great for all kinds of projects that need distance measurements. The HC-SR04 is inexpensive and easy to use. We will be sending signals directly to the sensor and interpreting the results without the need for a library. Ultrasonic sensor module HC-SR04 provides a 2cm-400cm non-contact measurement function, the accuracy can … Read more

Arduino Uno Super Starter Kit Servo

Arduino Uno Super Starter Kit Servo

The servomotor, RC (Hobby) Servo is a type of gear motor that can only rotate 180 degrees. It is controlled by sending electrical pulses from our UNO R3 board. These pulses tell the servo what position it should move to. We will be wiring the servo to our Arduino UNO R3 controller on our super … Read more

Arduino Uno Super Starter Kit Tilt Ball Switch

Arduino Uno Super Starter Kit Tilt Ball Switch

We will now look at the tilt ball switch on our Arduino Uno super starter kit. Tilt sensors (tilt ball switch) allow you to detect orientation or inclination. They are small, inexpensive, low-power, and easy to use. Their simplicity makes them popular for toys, gadgets, and appliances. Tilt ball switches are sometimes referred to as … Read more

Arduino Uno Super Starter Kit Buzzers

Arduino Uno Super Starter Kit Buzzers

We will now look at active and passive buzzer outputs on our Arduino UNO controller. Electronic buzzers are DC-powered and equipped with an integrated circuit. They are widely used in computers, printers, photocopiers, alarms, electronic toys, automotive electronic devices, telephones, timers, and other electronic products for voice devices. Buzzers can be categorized as active and … Read more

Arduino Uno Super Starter Kit Analog Inputs

Arduino Uno Super Starter Kit Analog Inputs

We will now be looking at how to use analog inputs to our Arduino UNO controller. An analog input converts a voltage level into a digital value. This can then be used in our Arduino program or sketch. The analog input signal can represent many different items. Speed, levels, distance, brightness, density, humidity, etc. are … Read more
