nRF24L01 wireless communication (Failed, response timed out)

Hello All, I recently purchased two nRF24L01+PA+LNA units. I have connected each nRF24L01+PA+LNA to their own separate Arduino Uno (using jumper wire cables), and both Adruino Unos are connected to the same computer. I downloaded Maniacbug's RF24 library, and am now trying to run the "GettingStarted...

Traffic light code (beginner level coding)

Hello all! I'm a new member to the arduino community. I received my duemilanove yesterday in the mail and she is indeed a beauty. This morning I started familiarizing myself with coding and decided "why not make my own?". After an hr or 2 (lost count) of trial and error, I finally came up with this ...

Interfacing RC-522 RFID

Hi, can anybody help me, how to use RC-522 RFID device, with ATmega? I have downloaded an example program yet, but it used "RFID.h" which is not included in the basic Arduino libraries. Can I use RFID without special library? If I can't, where can I obtain the appropriate library from? Thanks for th...

Pure Sine Wave Inverter Design

I am designing a pure sinewave inverter, 220V, 50 Hz. Here is the complete design, http://i.imgur.com/QpX93md.png without filter i simulate the whole circuit and tried to plot the current waveform by placing a current probe in RL Load (R = 5 Ohm, L = 16 mH). I should be getting a sinusoidal current ...

Problem with Nrf24L01+ and arduino mega

I have two Arduino (a mega and nano) and two nRF24L01 + to communicate them. The connection of the wires according to the library and using the SPI pins modeled on arduino. NANO 328: MISO -> 12 MOSI -> 11 SCK -> 13 CE -> 8 CSN -> 7 GND -> GND VCC -> 3.3v MEGA 2560: MISO -> 50 MOSI -> 51 SCK -> 52 CE...

can we interface a webcam and a PIR motion sensor to an arduino...???

Can we interface a webcam and a PIR motion sensor with an Arduino…? I want to connect a PIR motion sensor and a webcam to an Arduino… when a human enters a specified region…the PIR motion sensor will send a signal to the Arduino… the Arduino then sends an actuating signal to the webcam so that it sw...
