Making sounds with a piezo
'Piezo' normally refers to an electrical component which can be used to make sound, however more broadly a piezo is a component that is susceptible to the two-way piezoelectric effect where pressing or squeezing the piezo element can create a small voltage, an...

Using a Sparkfun Sound Detector
The Sound Detector is a board made by Sparkfun electronics that provides a way to detect ambient sound levels. There are three connections on the board: Audio - This is the raw audio from the microphone. Envelope - This is a analog value representing the vo...
How to connect a push button or switch
Buttons and switches are a way of opening and closing a circuit, i.e. making and breaking a connection as one of the most rudimentary forms of sensor you can use with an Arduino. There are dozens of different types of switches and buttons, but at their most ba...

Using a HC-SR04 distance sensor
The HC-SR04 is a ultrasonic distance sensor, it uses ultrasound to send out a ping and measure how long the sound takes to come back, exactly like bats use to fly in the dark. The sensor works between 2-400cm however if the ping sound is reflected away from th...

Connecting a Potentiometer
A potentiometer (often abbreviated to pot) is an electronic component with three connections, the main purpose of the pot is to create a variable voltage as an input to a circuit, for example controlling how loud your speakers should be. Inside a potentiomete...
How to connect a Light Dependent Resistor (LDR)
An LDR or Light Dependent Resistor is a component which restricts how much power can flow through a circuit based on how much or little light hits the sensitive part on the top. Wiring To use a Light Dependent Resistor, we have to use it in combination with a...
