Wii Nunchuck controlling ArduRover

ArduRover V1This is to connect a Wii Nunchuck to the ArduRover and then, by moving the Wii Nunchuck move the rover instead of just using Serial and WASDX to control it.The first thing to know is that I didn't document everything for the first two Wii Nunchuck demos.I am pretty sure I bought my wii …

Arduino Mega put bootloader on different Arduino Mega

At one time I was attempting to upload TFTP bootloader to my Arduino Mega.  Something happened during that upload (partially b/c the bootloader can't be uploaded via my pocket programmer) and the power went out on the programmer and I bricked my Mega.On your Master Mega -load the ArduinoISP sketch from the Exampleschange the Programmer …

BLE + OLED + Arduino MEGA + iPhone 4s

This is geared towards my iPhone 4s, but really any BLE (Bluetooth 4.0) enabled device will work.The first thing is to go out and read this: https://learn.adafruit.com/getting-started-with-the-nrf8001-bluefruit-le-breakout/introductionor this: https://learn.adafruit.com/downloads/pdf/getting-started-with-the-nrf8001-bluefruit-le-breakout.pdfDone?  Good.Previous tutorials have worked with the SainSmart OLED which uses a 1306 SSD (the code for this can also be found at Adafruit for their graphics - https://learn.adafruit.com/monochrome-oled-breakouts/arduino-library-and-examples).The nrf8001 …

HC-05 Bluetooth

VCC - 3.3VGND - GNDTXD - D12RXD - D11KEY - D13LED -That's it - Then you can connect to the bluetooth you desire.  After you pair, the code is 1234 which may be changed by the AT commands.http://geekinc.ca/using-screen-as-a-serial-terminal-on-mac-os-x/http://www.instructables.com/id/Arduino-AND-Bluetooth-HC-05-Connecting-easily/?ALLSTEPS

SD Card and Arduino Nano

In a follow up to my last post I decided that since I was integrating these sensors on a Nano I should actually prove that as well.I took to the Arduino Nano schematic so I could figure out which pins are which.http://arduino.cc/en/uploads/Main/ArduinoNano30Schematic.pdfI don't remember where I found this PNG (one of the Aruino forum posts), …

SD Card and Arduino Mega

I purchased this awesome little SD card breakout from Sparkfun about 2 years ago https://www.sparkfun.com/products/12941 - a lot of family issues came up and I wasn't able to work on it with the kids like I wanted to.  With some recent work I'm doing with sensors (more blog entries to follow) I also know I'll need to …

IR Emitter and Detector

About 2 years ago I worked for a company that made hardware and went on a RadioShack buying spree.  I bought an IR Emitter and Detector, but didn't know anything about hooking them up.  Over the couple of weeks I've gotten back into wanting to do some cool stuff with electronics including sending some sort …
