Incorporating the Radio Into the Turrets

Portal 2 Turret – Master Turret Control Using Arduino

Leave a Comment / Using Arduino / By

This project is an extension or remix of my original Portal Turret on Instructables (Portal-2-Turret-Gun). It can also be used as a cheap controller to control anything that uses the nRF24L01 radio chip. The LCD screen is particularly useful when customizing. (It turns out to be quite useful in checking when my radios establish and …

FabECG: a simple electrocardiogram board using Arduino

Leave a Comment / Using Arduino / By

Technologies for rudimentary physiological sensing are getting cheaper and easier to implement. Consider, for instance, these non-contact sensors from UCSD which can be used to take an EEG through hair or an ECG through a T-shirt! One can even make a simple oscilloscope to digitize, store and view the signal using only a Tiny45 micro-controller and a …

Arduino 7 segment Displays Digital Clock With Charlieplexing LEDs

Leave a Comment / Using Arduino / By

This is my second instructable. I just had a mood of making a digital watch. But wanted to make it a learning process. I already had a sanguino i could have easily used that Atmega644 chip. it would have been more than enough.  But i wanted to try burning a Arduino bootloader and see if i could make it work. …
