This circuit demonstration showcases a random LED flasher controlling twenty lights. LED flashers and sequencers are commonly employed in decorative lighting applications to produce aesthetically pleasing color patterns. Rather than steadfast illumination, these systems cycle LEDs on and off in either a predetermined sequence or at irregular intervals. The latter approach generates a more dynamic, […]
Este es el primero de 5 instructables que surgieron del Instructables & Sugru build night (and day en nuestro caso) que hicimos en el Laboratorio de Juguete, el 20 de julio del 2013: una Resistencia Flexible o Flex Sensor hecha con Sugru y polvo de grafito: ——————————————- This is the first of 5 instructables from Instructables […]
Remote visualization of real-time sensor data. This tutorial describes in detail how to use the free SensorMonkey service to push real-time sensor data from an Arduino to a webpage for visualization using Processing.js. No server-side coding or Ethernet shield is required. A standard, run of the mill Arduino will work perfectly. You’ll also need a sensor to […]
GoFly is a project based on PNA (car navigation devices with Windows CE), LK8000 tactical fligh computer software and variometer (altimeter) external input based on Arduino board and pressure sensor. Why? -You can build this for about 150$, -Your ordinary PNA (Personal Navigation Assistant) changes to really nice, high end flying computer, with lot of […]
Being able to control everything from your pocket has long been a dream shared by many. Previously we’ve had universal remotes that can both control our TVs and radios, then we had wireless wall sockets. Both great things, but how likely is it that you’re going to be carrying around those remotes with you everywhere […]
In this tutorial you’ll learn how to use a bluetooth module and MIT’s app inventor to create a wireless serial link between an android phone and an arduino board. Here is a short video showing an example app I created. I’ll describe how to do the wiring, write an arduino sketch that can accept basic […]
What are we messing with? IoT (Internet of things) set-up to operate/control 220-240 Volt AC Bulb/Device NodeMCU Amica + 5V Relay + MQTT + Arduino IDE + Web Browser (HTML + JavaScript/jQuery) WARNING!! – THIS PROJECT INVOLVES WORKING WITH HIGH VOLTAGES THAT CAN CAUSE SERIOUS INJURY, DEATH, AND/OR SET YOUR HOUSE ON FIRE. PLEASE PROCEED […]
Step 1: COMPONENTS REQUIRED Only 4 components required – 1. ESP8266 NODEMCU or WEMOS D1 mini or any esp8266 wifi development board2. RELAY (5V or 6V)3. ULN2003 or UNL2003A (Relay driver IC)4. Jumpers (obviously or else solder it!!) The main structure of the project is that ESP8266 module will receive the signal from the MQTT […]
Overview As enthusiasts of audio, we aimed to use our recent understanding of microcontrollers to create an exciting consumer gadget. Our project is a drum machine that functions as a step sequencer. The user can create a 16-step percussion sequence with various percussion instruments on six separate tracks. The user switches between various music tracks […]
LED displays are commonly packaged as arrays of LEDs organized in rows with shared positive terminals and columns with shared negative terminals, or vice versa. Here is a standard illustration, along with its diagram: These exhibits can be very useful. To control a matrix, you connect its rows and columns to your microcontroller. The columns […]
