About two years ago I also bought Lelo toy just to find out that the remote is useless...about zero distance!
Then I came accross Beth's website and was intriqued in her effort to enhance the Lelo remote.
The enhancements are at least 10 meters distance and stronger motor.
The lelo toy were just lying in a cupboard to rot. So it becomes the ideal hack.
It is excellent engineering done by this lady Beth.
I put the small little project together and I learned from the project in more than one sence.
First of all the Sparkfun serial 7 segment display needed to be mastered. On this board is a 328 in full and you programme this board with usb serial. It actually programmes just fine without the 104 capacitor in series with the reset pins. After studing the schematic of the display I noticed SDA and SCL to be A4 and A5 in the Arduino code regarding connecting the sonar sensor HC-SR04. the transmitter breakout board module is the CC2500
Note I only used the Arduino Uno to power the rest of the project. The 2500 tx operates on 3v3!
Here is my hand written schematic:
It is better to download her code with all relevant libraries, including "runningmedian.h, leloremote.h and even the Sparkfun 7 seg display libraries and addons for Arduino.
If you want to use the remote without the sparkfun serial 7 segment display, upload the code to your arduino as given on her website with the following connections:
SI to Arduino 11
VCC 3V3 DC
SO to Arduino 12
CSN to arduino 10
CLK to Arduino 13
Trigger to A4 on Arduino
Echo to A5
