A circuit based around an op-amp might fit the bill, but since it's not a typical requirement for the sorts of circuits used with an Arduino it won't be covered here A simple, low-performance solution to the problem that would work with the hardware described in this project unchanged is to use analog inputs and apply a scaling factor to the readings This would cause you to lose some resolution because only part of the input range would be exercised, but it may be acceptable in some situations It's also possible to change the ADC input range by changing the analog reference voltage More information on this technique is available on the Arduino site at: wwwarduinocc/en/Reference/AnalogReference.

PtrToStringChars works only when marshaling to wide (Unicode) strings. This makes sense, since the underlying string data held within a System::String object is Unicode. Since we re directly accessing this data via the interior pointer, no Unicode-to-ANSI conversions are possible.

There are a number of different Arduino-based oscilloscope and logic analyzer projects, and they should all work with the hardware described in this project simply by changing the program on the Arduino and the program you run on the host. Experiment with a few and find the one that suits your needs best. Poor Man's Oscilloscope: accrochages.drone.ws/en/node/90 Arduinoscope: code.google.com/p/arduinoscope/ Macduinoscope: www.gabuku.com/scopeAVR Logic Analyzer: www.uchobby.com/index.php/2008/09/09/avr-logic-analyzer/ The Arduino site has some useful pages explaining how the analog inputs work as well as background on the direct port manipulation we used in the digital sampler program in this project. www.arduino.cc/en/Tutorial/AnalogInputPins www.arduino.cc/en/Reference/PortManipulation

//the ansi version static char* ProcessString( const char* stringIn) { size_t bufSize = strlen(stringIn) + 50; char* pResult = new char[bufSize]; strcpy_s(pResult, bufSize, stringIn); strcat_s(pResult, bufSize, "AddedANSIString"); return pResult; } This method is added to the same unmanaged CStringUtility class just shown. The managed method that calls the ANSI version of ProcessString is implemented like this: using namespace System::Runtime::InteropServices; void ChangeTheStringAnsi() { //marshal the managed string to unmanaged Ansi IntPtr pStrPtr = Marshal::StringToHGlobalAnsi(m_Target); const char* pStr = static_cast<char*>(pStrPtr.ToPointer()); //pass the pointer to the unmanaged method char* pNewStr = CStringUtility::ProcessString(pStr); //update the managed string with the result m_Target = gcnew String(pNewStr); //free the pointer to the new string delete [] pNewStr; //free our original marshaled string Marshal::FreeHGlobal(pStrPtr); } This method is added to the ManagedStrings class. Looking at the code, we see that it calls Marshal::StringToHGlobalAnsi to convert the System::String instance to an ANSI string. The result of this method is an IntPtr that is then cast to a char*. When we are done with the char pointer, we use Marshal::FreeHGlobal to free the memory that we allocated. Here is the code used to test these methods: ManagedStrings^ obj = gcnew ManagedStrings(); obj->Target = "abcdef"; Console::WriteLine("String prior to call: {0}", obj->Target); obj->ChangeTheStringAnsi(); Console::WriteLine("String after Ansi call: {0}", obj->Target);

Water is a precious resource in many parts of the world and many people rely on water tanks to supplement their water supply by storing collected rainwater or water pumped from a well or bore But how do you measure how full a tank is Tanks are constructed of opaque material to prevent algae growth and are often kept closed up to prevent mosquito infestation or access by rodents, so it s inconvenient to physically look inside And besides, having a way to measure tank depth electronically opens up a world of possibilities, such as automatic control of pumps to fill tanks when they get low or to disable irrigation systems when not enough water is available The obvious way to measure tank depth is by placing a series of conductive pickups at various heights inside the tank and measure the resistance between them.

When the code is executed, the results look like this: String prior to call: abcdef String after Ansi call: abcdefAddedANSIString
