AC Dimmer Circuit: 46
Posted on: 02 Mar 2015
Green wire is zero_cross signal, goes to Arduino digital pin 2 in. Yellow wire is light dimming signal, comes from Arduino digital pin 11. The LED on board should dim or fade along with the AC light source. Fading will not work until AC power is connected, it depends on the zero-cross info from the […]
Hybrid Play: Turn any playground into a video game

Zigbee Wireless Relay Control and Power Monitoring System
Posted on: 05 Feb 2015
Introduction We designed a system for wirelessly controlling relays and monitoring current. This is used for a home load simulation. By wirelessly turning relays on and off by sending commands from a PC to a microcontroller we can change the total load (current) to our simulated home. For wireless communication, we used XBee Series 2 […]
Arduino Seven Segment Display Tutorial
Posted on: 24 Jan 2015
How many TV shows and movies have some mysterious device counting down to zero those displays are 7 segment displays.With the 7 segment displays you can display any number or some alphabets that your heart desires. At first controlling a 7 segment display seems quite complex but it quickly becomes clear. What follows is a […]
Breathalyzer using an Arduino
Posted on: 15 Jan 2015
What is a breathalyzer you may ask? It is a device for estimating blood alcohol content (BAC) from a breath sample. In simple terms it is a device to test weather a person is drunk or not. As the title suggests it runs on the Arduino. Our breathalyzer uses the MQ-3 alcohol sensor from sparkfun. […]
Arduino Digital Switch Code
Posted on: 15 Dec 2014
This is basic for your arduino projects, input switch read from digital input. When ever switch pressed, LED will turn on. Instruction; 1) Connect cathode lead of LED (shorter lead) to ground pin and anode lead of LED (longer lead) to pin 13. 2) Add switch to breadboard, connect one of the switch […]
ADXL3xx Accelerometer using an Arduino
Posted on: 12 Dec 2014
This tutorial shows you how to read an Analog Devices ADXL3xx series (e.g. ADXL320, ADXL321, ADXL322, ADXL330) accelerometer and communicate the acceleration to the a personal computer. This tutorial was built using the breakout boards from Sparkfun. The adafruit accelerometer breakout board also works, though it must be wired differently. The ADXL3xx outputs the acceleration […]
4x4x4 LED-cube based Arduino and Flower protoboard
Posted on: 09 Dec 2014
This instructable will teach you how to build your 4x4x4 LED cube with Flower ProtoBoard and control by Arduino. Why is Flower ProtoBoard ? not ProtoBoard ? Because of I often use protoboards to test out if a new idea works in practice. I do not use breadboards anymore because I pretty much use only smd parts […]
DIY Arduino FM Radio Shield
Posted on: 26 Nov 2014
I’ve been visiting local convenience store (Dollarama, here in Montreal, Canada) and notice nice looking FM Radio, just for only $3. Why not to try to interface it to my lovely Arduino? Idea looks quite challenging, the same time what is the point in interfacing a DSP radio shield to arduino? I don’t need a […]
SOLAR POWERED ARDUINO WEATHER STATION
Posted on: 21 Nov 2014
In country like India most of the people are dependent on agriculture.For effective planning in agriculture weather forecast is of utmost importance.So farmers are always interested in the Weather Forecasts.As farmers stay in remote areas, they have to wait for the news updates in tv, radio or news papers.Unfortunately this weather information is not the […]
