This project uses green surface-mount LED’s along with an AVR ATTiny45 microcontroller to simulate the behavior of fireflies in a jar. (note: the firefly behavior in this video has been greatly sped up in order to be easier to represent in a short film. The default behavior has significantly more variance in its brightness and …
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 …
Lumileds has added news LEDs to its Luxeon IR Domed Line with a significant increase in both DC and pulse drive current–up to 1.5A and 5.0A, respectively. The new emitters deliver radiant power of 1350mW at 850nm wavelength (slightly visible) or 1450mW at 940nm (invisible or covert IR). These new IR LEDs are engineered to …

There are so many authentic looking lightsaber build guides but not many on building a super long lightsaber. Regarding Star Wars, I’m not sure why lightsabers are normal sword size anyway. Its not like the longer the lightsaber, the harder it would be to swing. I assume they are essentially weightless. Just make it 10′ …
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 …

Supplies Arduino Uno Bread Board Jumper Wires LED 5mm 5V (Any Color) 9pcs Resistance 220 Ω A Working PC Step 1: Placing the LED Bulbs Place all the LED bulbs on the bread …
SjoelSim! Is a mixed-reality version of the popular and historic Dutch shuffleboard game “Sjoelen”. The circuit makes use of two HC-SR04 ultrasonic distance sensors to measure the X and Z velocity of a playing disc. In combination with a program built in the Unity Engine, it makes for a pretty good alternative to the real …
The very first project of my channel is about controlling an RGB LED using annoying push buttons…. I feel that the project was not a good one to learn about micro-controllers, because most of the micro-controllers uses are not fully utilised in that project…. So, This is definitely the time for an upgrade, and upgrade means letting …

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 …

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, …
