AM Transmitters Arrived
Farnell delivered two packages, ordered at 4PM, the next day via UPS – very impressive, must have costed more than the £8 it cost me (free P&P).
So, with the help of the arduino playground and homeeasyhacking, my arduino could receive and transmit home easy messages.
The photo shows my prototype of all parts of the project (ambient light – bit of paper coiled up, will be improved soon – and home easy controller).
Wire the data line of the receiver (any of the two work on my receiver) to pin 8, and the data line of the transmitter to pin 6, and connect power/ground/aerials accordingly (I haven’t used an aerial for the receiver yet). A 23cm piece of wire works well as an aerial. All my cables are strands from CAT5 – I’m a cheap-skate!
To use the following code, first download the HomeEasy package from homeeasyhacking, add the .h and .cpp file (Sketch > Add File), then copy and paste the following code. Upload it, then start the serial monitor.
Press a button on a home easy remote and you should see the sender code – copy this, and replace “2427994″ in the code below with yours. Then restart the program, and whatever you programmed the first button on the first slider of the remote should turn off and on. Make sure, unlike me, you haven’t plugged your computer into that device – I eventually got the code working only to kill my computer’s power, oops!
To control another device, change the setHEDevice(0) line.
