So my boss came to me one last week and said he wanted to scare the trick-or-treaters who came to his home, and the kids who would come to work during a special Halloween Walk the community does. Thus was born the talking pumpkin. In short, I used an Arduino, an SD card read/writer, and an ultrasonic sensor to trigger a sound byte when the kids walk past our pumpkin… something they would not expect. If you ...

Basics of Turning your Remote Controll Vehicle into an Autonomous System (Drone) Using an Arduino

I began this project with the objective of cheaply turning my RC helicopter into something of a UAV or at least to fit some sensors to reduce collisions and other "mis-haps." Now unfortunately at the beginning of the project i miscalculated my little helicopter's lift capabilities and so with the equipment fitted it has insufficient power to get more than a couple of inches of the ground, but all of the sys ...

Simple USB Isolator

This is the PCB from https://github.com/vhs/vhs-pcbs/tree/master/usb-isolator. No components are included, PCB only. In one of the earlier SMD workshops I've running at VHS I managed to temporarily kill my new macbook pro when I plugged in a partcipant's prototype. I revived it by removing the back cover and disconnecting the battery all the time chanting to myself, must get a usb isolator, must get a usb i ...

Webserver for home appliances control

This instructable describes how a simple but powerful webserver used for controlling of home appliances can be done. The hart of the circuit is the ATmega328 microcontroller. I have chose this because I wanted to use all available Arduino libraries compatible with them. The Ethernet chip used is ENC28J60. A lot of Arduino libraries exist also for it. The webserver is designed in the way that it control 4 ch ...

Mini line tracer

This is the story of how i made my first robot, and the instructions to build one yourself. It's a simple line tracer, controlled by two op-amps. No microcontroller, no programming... simple analog circuitry. I tried to make it as small as possible, using SMD components and tiny motors. I'm very happy with the final result, the robot can follow 1-2cm wide black lines on white background, and is quite fast. ...

Analog Read Voltage using Arduino

This example shows you how to read an analog input on Pin 0, convert the values from analogRead() into voltage, and print it out to the serial monitor.  Circuit: image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect the three wires from the potentiometer to your Arduino board. The first goes to ground from one of the outer pins of the potentiometer. The second goes ...
