MPU6050, BeagleBoard, KiCad, PCB and Stuff

Hi, As mentioned in my earlier post, I am moving towards interfacing MPU6050 with BeagleBoard. MPU6050 operates at 3v3 and BeagleBoard at 1v8. The I2C buses too use on the same voltage levels. The MPU6050 has an internal pull up resistor. For those who still do not get the issue, here it is explained in […]

Wireless Intruder Detection System

Hello everyone, This is an informal project done with help of Arun Prasad and Sreejith Sir. The project aims at detecting an intruder in a secured environment. For these we use PIR ( Passive infra-red Sensors ) and Independent Xbees. Independent nodes were used. Custom PCB designs were made to sustain an Xbee module, PIR […]

2 way (Peer-to-Peer) chat system using Xbee

Hello everyone! Today I will write about a small chat client which I had made using Xbees. It is a peer-to-peer based chat system. Here I describe using only two nodes, but later in the post, I shall explain on how to develop chat system with more than 2 nodes. Firstly for a simple 2 […]
