“I have been working on making homemade motion sensors that send an email message when triggered. There are many example instructables and other examples of doing this. I recently needed to do this with a battery operated PIR motion sensor …
“An automated humidor using an Arduino — with or without building your own humidor. Introduction ‘A cigar is as good as the memories you had when you smoked it.’ I can agree on that, but a sharp and bitter cigar will …
“An IoT lamp with gesture seonsor, temperature sensor, and multiple light effects. Into For a very special woman, I needed a very special and unique present. Something really cool. How about a NeoPixel lamp, that can be controlled with a …
“Long time no post! Now that’s out of the way… As ever, I’m always on the search for cheap electronics and this board is nearly mind blowing given both the price and form factor you can get it …
“In my last instructable, I made an infinity mirror with white lights. This time I’m going to make one with colorful lights, using an LED strip with addressable LEDs. I’ll be following a lot of the same steps …
“Function generator is a very useful tool, especially when we are considering testing our circuit’s response to a certain signal. In this instructable I’ll describe the building sequence of small, easy to use, portable function generator. Features of …
“In this project, I will use RF modules with Pic 16f628a. It will be a short tutorial about rf. After you learn ho rf modules communicate with each other you can use these modules with pic microcontroller, ardunio or any …
“We all use and love the Arduino boards for our projects. But sometimes it can happen, that a software or hardware error causes a lot of frustration, by stopping out little board from running 24/7. For this reason Arduino …
“This project is about a simple inclinometer featuring auto rotation of display. This inclinometer can be rotated in any position keeping the digits readable even upside down! It is controlled by an Arduino 101 driven by accelerometers to read the …
“This clock has been designed so that you can take it apart and see how each section works from the power supply up and you can watch the numbers travel through the boards. There are 283 transistors in this clock …
