If you need an Arduino to shut off from within your Sketch, this is the solution. We will explore wiring the Pololu Pushbutton Power Switch, programming the Arduino to shut off the power, and making the unit “power on” only. The Pololu Pushbutton Power Switch comes in two versions – the SV version geared towards …

Introduction: Our main goal with the Tiich system is to design a teaching aid/tool which would replace the conventional whiteboard in a classroom environment. We want our system to be used as an electronic based white board, having all the written information easily be saved and submitted to all the students in the classroom. We also …

Throwies are great. They have a minimal parts count – 2 or 3 depending on whether you use a magnet – and produce a great effect. They are very cheap and easy but not highly efficient: 1) They are on all the time, so on average they waste half of their energy shining during the day. …

The Arduino offers the advantage that a lot of people are using it so it is usually quite easy to get help or information via the internet. The main website for the Arduino is: http://www.arduino.cc/. The Arduino can also be programmed to behave in many different ways. It has 6 analog pins (continuously varying controls like …
Arduino Project – Touch Me Not I modified the Arduino project from the Arduino Starter Kit (Touch Sensor Lamp). Now it lights up an LED when your hand is close on the aluminium foil (without even touching it). This can be used as a ‘Touch-less Switch’. I just did it because it seemed pretty cool …
PID Thermostat This is a PID thermostat for the arduino. It supports independent tuning parameters for multiple hardware ‘profiles’, and includes an autotune mode to estimate the PID parameters for a given setpoint. Installation Hardware DS18-series (I’m using the DS18B20) temperature sensor Solid-state relay rated for your power source 16×2 LCD display (I’m using the …
A light meter is a device that measures the intensity of light. It finds applications in schools, hospitals, production areas, passageways and more to measure and maintain proper lighting levels. It is often used by photographers to determine the proper exposure for a photograph. Today we are going to build a simple light meter using …

Let’s learn to sense movement in a room with a PIR motion sensor and Arduino’s digital input. We’ll connect up a circuit using a breadboard and use some simple Arduino code to control a single LED. We’ll use Tinkercad Circuits to simulate the circuit so you can follow along even without any components, and show …
An if statement allows you to choose between two discrete options, TRUE or FALSE. When there are more than two options, you can use multiple if statements, or you can use the switch statement. Switch allows you to choose between several discrete options. This tutorial shows you how to use it to switch between four desired states …
