What Fun for the Holidays! Arduino Style!!

So for Christmas I received a ladyada's electronics bento box from adafruit.com and some awesome parts for my Arduino and random projects. After getting some pink LEDs (no I did not ask for pink) I have been tasked with building a nightlight for my oldest daughter. The final project will be on a protoboard and will be under some fabric in the shape of a flower. I was working on building it with an Uno but realized I could more simply build a circuit that would turn on in the dark with a transistor and a few spare parts. You can see from the pic below the final circuit is fairly simple.Here is a picture of the light and the 5V regulator circuit I made. This is where the first prototype was made the second version is in use in my daughters room. I will try to get a picture of it soon.



I also got a range sensor and have created a reactive color changing light. The light changes what colors it cycles between and the speed at which it changes based on how far away people are from it. I have included pictures below. I will post the code when I have it all worked out and running how I want it to. All in all I have to say it has been a fun Christmas and a good year I now have some good tools and parts and great plans for my little Arduino.

ESP-01 Programmer for ESP8266

Image
I have been working on a new wifi enabled version of the pumpkin project and as part of that effort I am using ESP8266 modules. The issue I was having is that programming them via breadboard was kinda bulky and when I ordered a PCB for a programmer it turned out to have an error in the design. The solution was to create my own. I wanted something that was minimal in parts and would just get the job done. The final product is a simple PCB with 4 components attached. To program you hold down the program button and tap the reset button and BAM! it is ready to be programmed. I left out a 3.3v regulator like lots of the other designs out there since I always use FTDI friends that have a 3.3v setting. it has made programming way simpler. I hope you find it as helpful as I did also ordering it via OSH Park 3 boards only cost $3.10. For the build you will need: 1 - PCB from OSH Park - https://oshpark.com/shared_projects/XPf6uyN1 1 - 6 pin right angle header for FTDI -  609-3313-ND 1 - 2x4 pin

Arduino Dice Box: Round One

Image
Description: I have not had much time to play recently. I was meaning to post this for some time now. I present the first iteration of my Arduino Dice Box. This project is a 5 way nav switch and a LCD display with I2C backpack that lets you roll virtual dice of various sizes and quantities. The program uses the random number function tied to an open pin to generate all the rolls. I have still not decided on a housing for this project and I am thinking of making another version that can use an 8x8 LED grid instead of a LCD display. So, lets get to it. The Parts: 1 x Arduino Uno 1 x 5 Position switch ( http://www.parallax.com/Store/Sensors/PressureFlexRPM/tabid/177/CategoryID/52/List/0/SortField/0/Level/a/ProductID/615/Default.aspx ) 1 x LCD 16x2 display ( http://www.adafruit.com/products/181 ) 1 x i2c / SPI character LCD backpack ( http://www.adafruit.com/products/292 ) The Buildout: The switch is wired up to pins 2-6. The switch is wired with built in pull ups so you will want to wire

The Pumpkin Project: Part Two

Image
Today we have the build pictures and code. There will be a final post covering the final set up on Halloween so keep an eye out for that. It will include video of the final setup. The Hardware: 1 - PIR sensor -   http://www.adafruit.com/products/189 1 - 15ft phone wire -from Wal-mart 6 - LED flicker candles - from Target 5 - red flicker LEDs - http://shop.evilmadscientist.com/productsmenu/partsmenu/576 10 - 220 Ω  resistors - from that compartment in my tool box 6 - Some random proto boards -  https://www.sparkfun.com/products/8885  and  https://www.sparkfun.com/products/8847 1 - Arduino Uno 1 - Raspberry Pi 1 - Powered Speakers - had some laying around 1 - Wireless card - had 3 laying around The Build: The first step was taking apart some cheap flicker led candles and clearing out space inside. After the led is removed the post holding the led can be removed from inside and the plastic guide for the power switch can be removed too. You will also want to remove the contacts from the ba
