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 starter kit. Let’s get started. Continue Reading!

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 “mercury switches”, “tilt switches”, or “rolling ball sensors”.

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 passive. Turn the pins of two buzzers face up. The one with a green circuit board is a passive buzzer, while the other enclosed with black tape is an active one.

We will be wiring passive and active buzzers to our Arduino UNO R3 controller on our super starter kit. Two pushbuttons with pull-down resistors will control the buzzers. Pressing the first button will play a melody on the passive buzzer. A two-tone alarm will sound using the active buzzer when the other push button is selected. Let’s get started. Continue Reading!

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 a few items that this external input can represent.
Arduino Uno Super Starter Kit Analog Inputs
We will be wiring a 10K potentiometer to the first analog input of the controller. The Arduino Uno R3 from our Super Starter Kit will be used. As the analog values changes via our potentiometer, we will use PWM to change the brightness of an LED. We will look at how this conversion from analog voltage to digital is done. Values will be displayed on the built-in serial monitor of our Arduino IDE software. Let’s get started. Continue Reading!

Arduino Uno Super Starter Kit Digital Inputs


We will now be looking at using digital inputs (pushbuttons) to turn LEDs on and off. This will be programmed using our Arduino Uno R3 from our Super Starter Kit. Pushbuttons will allow actions to be performed that our Arduino program sketch will interpret and take action.
Arduino Uno Super Starter Kit Digital Inputs
We will be wiring two pushbutton switches. A pull-down resistor will be wired to the first switch and a pull-up resistor will be wired to the second switch. This will change the state of the input (High (1) or Low (0)) based on the wiring. Two LEDs will be wired to the outputs of the Arduino Uno. This will show the state of the switches and allow the switch inputs to modify the state of the LED. We will look at three different programs.
Eliminating switch bouncing will also be discussed and programmed using our Arduino Uno super starter kit. Let’s get started. Continue Reading!
