Arduino Uno Super Starter Kit LCD Display


An LCD (Liquid Crystal Display) is a great way to display information in our Arduino Uno controller. We will be wiring and programming an alphanumeric, two rows with 16 characters on each row. The display has an LED (Light Emitting Diode) backlight with adjustable contrast.

This white and blue LCD will display “Hello World!” on the top line and temperature on the bottom line. The thermistor temperature circuit created last time will be displayed in both Celsius and Fahrenheit degrees. Let’s get started. Continue Reading!

Arduino Uno IR Remote Control – Infrared


The IR (Infrared) remote control is a great way to incorporate wireless control of your project. Infrared receiver modules are simple and easy to use.
Arduino Uno IR Remote Control
In this post, we will be connecting the IR receiver to the UNO, and then use a Library that was designed for this particular sensor. In our sketch we will have all the IR Hexadecimal codes that are available on this remote, we will also detect if the code was recognized and also if we are holding down a key. Let’s get started.

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 circuits can be much quicker and are very accurate in measuring temperature.

We will be using the DHT11 sensor to measure temperature and humidity. A separate thermistor circuit will also be used to measure temperature on an analog input. This will be all done on our Arduino UNO R3 controller on our super starter kit. Let’s get started. Continue Reading!

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 reach 3mm. The modules include ultrasonic transmitters, receivers, and control circuits. We will be wiring the ultrasonic sensor to our Arduino UNO R3 controller on our super starter kit. Let’s get started. Continue Reading!

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.
