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 …
Sensors are one of the crucial things when it comes to building projects/robots. Many a times the sensor might be not available locally or it might take too long to ship. Smart phone have most of the basic sensors like proximity, accelerometer, light, magnetometer, gyroscope, etc. embedded and we can in fact use these sensors …

I wanted to make an easy and secure way to enter my garage. RFID was the best way to unlock my door, even with my hands full I can unlock the door and push it open! I built a simple circuit with a basic ATMega 168 Arduino chip and a ID-20 RFID reader to control …
This was a fun project. Push the red button, watch the dice ” ROLL ” then stop on a random roll most every time. The hart of this game is the ATMEL ATmega328P on a stand alone board. Powered by 4 AA NiMD batteries. Can you find the SECRET SWITCH in the main picture? Where is the SECRET SWITCH? …

https://youtu.be/gWZ6Z1ptUis What’s that smell? It’s noxious gas of course! If you’re in an environment where there’s a possibility of gaseous release of which you’d rather not breathe, why not build an automatic system for sensing and alerting you? The design for the Environmental Alert System is driven by my motivation to understand the concentrations of …
