Arduino Wattmeter: Measure Voltage, Current and Power Consumption

Metering – Instrument Projects / By Ibrar Ayyub

Being electronics engineers, we consistently rely on meters and instruments to gauge and study the functionality of a circuit. From basic multimeters to advanced power quality analyzers or DSOs, each device serves specific purposes. Many of these gauges are easily accessible and can be bought depending on the measurements needed and their precision. However, there

High-Power Control: Arduino + TIP120 Transistor

Sensor – Transducer – Detector Projects / By Ibrar Ayyub

Up until now, we have talked about working with a lot of low-power devices. Sensors, LEDs, ICs, and the like are all capable of being powered directly from your Arduino, but as many awesome 5 and 3.3v components as there are, eventually you will find yourself holding a 12v solenoid, motor, or light and wondering

SunAir Solar Power Controller for Raspberry Pi and Arduino

Solar energy projects / By Ibrar Ayyub

Ever wanted to build your own Solar Powered Raspberry Pi or Arduino system? SunAir and SunAirPlus are 3rd Generation Solar Charging and Sun Tracking Boards designed by Dr. John C. Shovic at SwitchDoc Labs. You can use this board to power your projects and add a servo or stepper motor to allow it to track

Diverting surplus PV Power

Development Board – Kits Projects / By Ibrar Ayyub

As mentioned on the Contents page, two different hardware platforms have been successfully used to support Mk2 PV Routers. [Update at 7/3/14: Since writing this article, I have developed a new hardware platform which has been specifically designed for this product. The main board has an integral power supply and RF module, and there is

Power Laces- the Auto lacing shoe

Other Projects / By Ibrar Ayyub

Also, check out Power Laces: Version 2.0 Why wait until 2015? Inspired by ‘Back to The Future II’, this project is less ‘Practical’ than ‘Proof of Concept’, but hopefully it’ll tide you over until Nike comes out with something more polished. This was also the first time I worked with an Arduino microcontroller, and I

Power Quality Meter ( PQ Monitor) using Arduino

Metering – Instrument Projects, Projects / By Ibrar Ayyub

Arduino UNO project, Power Quality Meter, someone would call it’s PQ Monitor or PQ Analyzer. I had already published one blog devoted RMS voltage measurements on full band 20 – 20 000 Hz audio signals. ( Following my own style, I’d refer to already published materials whenever it’s possible ). This time measurements performed on

Yet Another Arduino 110v Power Controller

Projects, Solar energy projects / By Ibrar Ayyub

This Instructable shows you how to build a four-gang outlet box in which each outlet is controlled via an Arduino (or any other TTL level signals). It differs from the other relay boxes in that it uses no circuit boards and has very few parts (one chip and 4 relays). Step 1: Assemble Materials/Review Plan Tools

Power Arduino with a cellphone

Phone Projects / By Ibrar Ayyub

Old cellphones are easy to acquire and they have built in lithium charging circuitry. What a wonderful base for a power supply for small mobile things. I hooked up a cellphone to the arduino with the ability to charge the cellphone when you plug the arduino into the usb port. Please note that this was

Hacking a Powerglove using Arduino

Game – Entertainment Projects, Projects, Sensor – Transducer – Detector Projects / By Ibrar Ayyub

First of all lets get this out of the way… It’s so bad This is going to be showing how to hack the Nintendo Powerglove. By hack I mean tap into the flex sensors and use the buttons and d pad and add anything you want. In my case I added an accelerometer. I got mine from

Power (Energy) Meter using Arduino

Metering – Instrument Projects, Projects / By Ibrar Ayyub

Part 1. Analog Front-End. Opto-Isolator. Looking at the Power Quality Analyzer display, I was wandering, if there is any error in the measurement results, introduced by transformer. Overall THD picture doesn’t change much, suspiciously drawing same chart in the morning and in the evening, when electrical grid load significantly differs. Obviously, to estimate effect of
