We created a LED matrix that shows a Pacman and a Ghost. The figure changes by pressing a button. Also, the ghost takes the color according to the external temperature. It means, if it is cold, the figure turn blue, but if it is warm outside it will change to red. Supplies 71 leds (led […]

In the previous instructable I showed you how to get started with IoT using the nodeMCU, in this instructable I will be featuring the Particle Photon which is an easy to use IoT device to get started with designing IoT projects. The particle photon is smaller than the nodeMCU and features STM32 ARM Cortex M3 microcontroller on

Description This little project makes a great ornament to hang in your window at Christmas time. It is a 20″ wide star with 50 “neopixel” leds around the perimeter. Each led is individually addressable and it is controlled by an arduino device which can be programmed to sequence the leds in various patterns. Depending on

Particle Photon is a tiny micro controller, just about the size of an arduino nano. But the photon is designed for easy IoT prototyping, it supports OTA updates to its firmware. So all we have to do is get it connected to the internet and we could do all the programming wireless, the photon uses a

This sketch uses the Serial.parseInt() function to locate values separated by a non-alphanumeric character. Often people use a comma to indicate different pieces of information (this format is commonly referred to as comma-separated-values), but other characters like a space or a period will work too. The values are parsed into ints and used to determine the color

Hi makers! This is my first instructables and I want to address some important things firts: I made this project with the idea of using the lest amount of tools so that everyone could do it! Even I don’t have lot’s of tools, only the strict necessary I’m not an electrical engineer or a coder,

OLED!! What is an OLED? OLED ( Organic Light Emitting Diodes ) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs can be used to make displays and lighting. Because OLEDs emit light they do not require a backlight and

Sometimes you need to do two things at once. For example you might want to blink an LED (or some other time-sensitive function) while reading a button press or other input. In this case, you can’t use delay(), or you’d stop everything else the program while the LED blinked. The program might miss the button press

Recently my wife has suggested that I should lose a few pounds in weight (too much time geeking out and not enough time in the gym). With that in mind -and in true nerd fashion- I wanted to create a method to see my progress, as well as having a constant reminder to stick to

A while back, we constructed a pair of LED skateboard truck-risers. That project was intentionally created without the aid of advanced tools and techniques. We decided to try the concept again but without limiting ourselves. This time around we used custom designed PCBs and 3D printed parts. There was no limiting ourselves to hand tools and
