“Soldering tiny SMD components can be quite challenging, but the process can also be automated. This can be done by applying soldering paste and baking it, either in a (reflow) oven or on a hot plate (like a cooking plate in your kitchen). Around the web, I’ve seen many DIY reflow ovens; in my opinion they have one big …

“Hello, I just made this little project, I hope you like it, as the title says it’s about how to use a keypad to set the DS1302, it’s one of the basic projects you can add it to your own project if you want to add other modules or functions… It’s very easy to understand and adaptable …

“This is a matrix keyboard running along with an LCD display and an Arduino Uno, the most basic that exists today. The purpose of this setup is to create a program that receives a password typed on the matrix keyboard, compares it with the correct password, and displays a confirmation message on the display. It is important to remember that …

“Weather Stations are a very useful devices, and as we increase our knowledge of the global weather, quantifying our own local experience is also popular. Integrating aspects of the weather to IoT is increasingly important. This project does not invent anything much new, but should give a working set of plans for a weather enthusiast to build their own station …

“Hello DIYrs, ever wanted to share your feelings with someone but there isn’t a trusted one around? Well, my cute little Eve has been created for exactly that purpose. She is a chatterbot, a very cute one in fact. You can share your experiences, feelings and most importantly, argue about different things; she is well-experienced at it Because that …

“There are many practical situations where we need to know the current absorption of a circuit branch, a motor or in general, an electric utilizer. Sure, we could just use a multimeter set on amps measurement, but this is not to point, in fact in this context, when we say know we mean to detect a value and transmit it …

“I wanted to make a project that combined two of my favorite subjects: science and music. I thought of all of the ways that I could combine the two domains, and, I thought that it would be interesting to make an Arduino play Fur Elise while displaying the pitch of the note in Hertz. Now that I have given you …

“ABSTRACT: In the United States, 25 million people in the world have asthma, a respiratory illness, that causes difficulty breathing. This illness can be triggered by many factors such as air quality, pollen, dust, temperature, etc. Once triggered, asthma causes ones throat to close, making breathing difficult and causing that person to become light-headed. The main solution to asthma is …

“This project is part of a bigger one but it can be a standalone project. It’s basically a clock with two buttons for setting the time and date. It doesn’t look that great on the breadboard with all those wires but it does the job and it can be simplified by using a I2C display, but I’ll …

“In this instructable, we walk through how I made a “Cyclone” - type arcade game using an Arduino. This game also includes a reaction timer mode. Let’s get started! A list of things you will need: Arduino Uno LCD Screen MCP23017 serial port expander 2 pushbuttons LEDs of differing colors (I used 3mm and 5mm LEDs in red, green, and …
