DIY Solar Tracker using Arduino

Introduction We aim to introduce young students to engineering and teach them about solar energy; by having them build a Helios as part of their curriculum. There is an effort in engineering to push energy generation away from the use of fossil fuels and towards greener alternatives. One option for greener energy is to use a device called a heliostat, which uses a mirror to direct the sun’s light onto a tar ...

Debounce an input using Arduino

This example demonstrates how to debounce an input, which means checking twice in a short period of time to make sure it's definitely pressed. Without debouncing, pressing the button once can appear to the code as multiple presses. Makes use of the millis() function to keep track of the time when the button is pressed. Circuit image developed using Fritzing. For more circuit examples, see the ...

DIY AM Radio with Arduino

After I finished my last project,  I coudn’t stop thinking how to build an AM receiver, that would also operate in conjunction with my little friend Arduino. To minimize a workload and complexity, especially with RF part of the circuitry, I come up to conclusion, that SDR (Software Defined Radio) is the best choice for hobbyist level project. There are 4 major functional parts so far ( work in progress! ): ...

DIY navigation device for blind people using Arduino and Android smart phone

In this project you can cover your eyes and let your smartphone navigate you to avoid obstacles, the application is mainly a DIY navigation device for blind people. I knew that 1Sheeld is about to launch a new text to speech shield, and so I contacted them to let me use it in this project and they accepted since I'm one of the early Kickstarter backers :D By using 1sheeld I made the text to speech part by o ...

The Pill Reminder using Arduino

Back in January 2014 I was at a meetup of Baby Boomer Makers at TechShop in San Carlos, California. We were going around the table, each taking a turn to talk about projects we'd like to do. Bob spoke up to describe a problem his elderly mother was having - she couldn't remember to take her medicines on time every day. Each week Bob found that his mother had either forgotten to take her pills one day, or sh ...

DIY Arduino FM Radio Shield

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 radio, I want to have fun experimenting with it, so  lets go to the bare metal! You, probably, could ...
