iBionics Insect Cyborgs NEW! Our recent paper on roach-bots in IEEE EMBC and the related video PLEASE FOR A BRIEF HISTORY of OUR PUBLICATIONS Controlled by neurons, muscles are the micro-mechanical actuators of the body. ArduinoBoardLeonardo Overview The Arduino Leonardo is a microcontroller board based on the ATmega32u4 (datasheet). It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor.

Water Tank Depth Sensor Water is a precious resource in many parts of the world, and many people rely on water tanks to supplement their water supply by storing collected rainwater or water pumped from a well or bore. But how do you measure how full a tank is? Tanks are constructed of opaque material to prevent algae growth and often kept closed up to prevent mosquito infestation or access by small rodents so it's inconvenient to physically look inside. And besides, having a way to measure tank depth electronically opens up a world of possibilities such as automatic control of pumps to top up tanks when they get low or to disable irrigation systems when not enough water is available.

Hello, Savants! From 0 to C - teaching programming witouth a computer Hello, Savants! [studio] Created by Ubi de Feo, “from 0 to C” is a new series of workshops that aim at teaching programming using a more creative and human approach. Through the use of tangible, hand-made objects, I try to establish a clear understanding of how a computer works and what a programming language actually is: nothing but an abstraction of what we can do as humans. “from 0 to C”, originates from the need to prepare students to hardware (in particular Arduino) workshops in the shortest time possible. During the past few years, as an Arduino trainer, I realized that while getting a LED to blink was fun, the real barrier lied in understanding the very simple code you needed to achieve it. in detail: setup(){ // code here }

Adafruit Arduino Selection Guide So many Arduinos, so little time... There are many different Arduino and Arduino Compatible microcontroller boards. Which one is right for your needs? This guide will help you to select a board that best fits your project requirements and/or level of expertise. Whether you are just learning the ropes or have specific project requirements in mind, the Adafruit Arduino Selection Guide can help you to make the right choice. No Arduinos were harmed in the making of this guide.

Popular ICs (A collection of all of these IC's is available here) "2x or 4x, etc." means that there are multiple identical circuits that can be used within the same IC package.Words with a small Upward Green Arrow are Clickable inks Like This to more information.Most ICs have a printed or embossed DOT or MARK on their case that shows the location of Pin 1, or the end of the IC that has pin 1 (See LM324 and LM386 below).Pins are numbered CounterClockWise from pin 1 as seen from the top. (Aside: WHY CounterClockwise? Answer: Because Vacuum Tubes were wired clockwise from the bottom!)How To Read Device DataSheets (LINK)JUMP to DIODES(click)

The $0 Android Oscilloscope « retronics I recently had to get rid of my rarely-used oscilloscope due to space restrictions and started looking at alternatives. The handheld devices started from about $70, but had known of some PC kits. I thought, couldn’t I just use the input for my PC sound card? So came across the Poor Man’s Oscilloscope.
