How to Hook Up > Accelerometers (Memsic 2125)

Every one knows accelerometers from Wii controllers and smart phones. Being fairly inexpensive, they’re a prime candidate for including in a DIY project. I’ll detail how to hook up a Memsic 2125 (most common) dual-axis accelerometer and measure its tilt in this post.

How to Hook Up > IR Emitter and Receiver

An IR receiver can detect infrared light emitted from an IR LED. This post details how to hook up both parts as well as detect a break in the signal between the two, which would allow you to tell if something passed between them.

How to Hook Up > Servos

A Servo, short for “servomechanism”, can rotate 180 or continuous 360 (depending on the type). Servos consist of a motor & a potentiometer and can easily be hooked up to an Arduino. This post details how.

How to Hook Up > A Simple Slide Switch

A slide switch can be used to toggle power on and off. This post will detail how to use a slide switch with a 9V battery and your Arduino.

How to Hook Up > Photo Resistors

Photo resistors measure light. The amount of light varies the resistance and determines a value between 0 and 1023. This post details how to hook one up to an Arduino.

How to Hook Up > Thermistors

A thermistor, or thermal resistor, can detect temperature since it’s resistance will vary depending on the temperature. This post will detect how to wire a thermistor to an Arduino as well as code to read a Fahrenheit value from it.

How to Hook Up > Potentiometers

A potentiometer is basically just a dial. Depending on its rotation, it will read in a value between 0 and 1023 to use in your Arduino program. This post details how to hook up a potentiometer to an Arduino.

How to Hook Up > Soft Pots

A soft pot works just like a regular potentiometer; however, instead of turning a dial, you slide (your finger) up and down the strip to change the values. This post details how to hook up to an Arduino.

How to Hook Up > Buzzers

Buzzers allow for simple audio output. Running them at different speeds allow for a variety of tones. This post details how to hook one up to an Arduino.

How to Hook Up > Buttons

A button is a simple switch with 2 values: on or off, which is 1 or 0 respectively. No surprise there. This post details how to hook it up and read its value into your Arduino program.
