Hacking the Rock Crawler – Part 3

AT the end -> A very trivial but important lesson - something that we all assume we know theoretically but might fail to implement practically !!. This is what the 4-bit level shifter  BSS328 module from Adafruit looks like -       My first step was to test the module , the connections were … Continue reading Hacking the Rock Crawler – Part 3

Setting up the transmitter and the receiver

So i am still waiting for the level shifters to come, meanwhile i wrote a code that would form the framework for the codes for the RC car so that i would not have to spend a lot of time in debugging. I made a shield for the receiver node that would rest on the … Continue reading Setting up the transmitter and the receiver

Hacking a Rock Crawler to run on 27MHz and 2.4GHz using nRF24L01+ transceivers – Part 1

I had this Rock Crawler (from now on rock crawler would be abbreviated as RC) that originally ran on 27MHz. This is NOT a differential drive vehicle, it uses a steering mechanism to turn. In the booklet that i received with this RC it was mentioned that the maximum range is 10 mts and it … Continue reading Hacking a Rock Crawler to run on 27MHz and 2.4GHz using nRF24L01+ transceivers – Part 1

RF24Network for Wireless Sensor Networking

The ultimate guide to Wireless Sensor Networking using nRF24L01+ and Arduino.

17-Node Party

RF24Network is a network layer for Nordic nRF24L01+ radios running on Arduino-compatible hardware. It’s goal is to have an alternative to Xbee radios for communication between Arduino units. It provides a host address space and message routing for up to 6,000 nodes. The layer forms the background of a capable and scalable Wireless Sensor Network system. At the same time, it makes communication between even two nodes very simple.

Today, I managed to get 17 nodes running on a single network. Now I need to build some more nodes, because the system worked great with 17, and could likely handle thousands of nodes.

Taking input from Processing and transmitting it wirelessly to control a remote set of leds

The nrf library allows us to send only integers , characters , bytes but not Strings objects (you can definitely send character arrays i.e strings). But it is really easy to communicate from Processing to Arduino using String objects because of the ease and the many ways in which we can manipulate Strings in complex … Continue reading Taking input from Processing and transmitting it wirelessly to control a remote set of leds
