ABOUT ARDUINO 

The TDL is compatible with the Arduino language, which is based on the ‘Processing’ language, which 
itself is similar to the C language. Most of the C/C++ core language can be used with the TDL device and 
the Arduino IDE software. You can create classes, use inheritance, composition, and other 
functionalities, but STL and exceptions cannot be used. Arduino first appeared around 2005 and is now 
used worldwide by over a million users. Jericho is not endorsed or linked in any sense with the Arduino 
company. The hardware from Arduino is distributed via a Creative commons license. Arduino clones are 
produced by hundreds of manufacturers around the world, with different qualities.

FREQUENTLY ASKED QUESTIONS (FAQ) 

 

- What is a thermistor?  

A thermistor is a tiny passive device which has an electrical resistance that varies with the temperature 
of its material. 

 

- Why do I have to connect the thermistor to a specific channel?

  

Each thermistor has unique parameters called Steinhart-Hart coefficients. Each channel is associated 
with a specific set of coefficients. Therefore, switching the thermistors would provide inaccurate 
temperature readings. 

One channel output is “-273.15”. What does it mean?  

The channel is empty or opened (false contact).

 

Can I use the TDL to do something else

?  

Yes, you can modify the product, software and hardware to add or remove capabilities. However, any 
physical modification of the device will void the warranty. 

I dropped the TDL in the water, what should I do?

  

Water will create short-circuits that will render the device unusable temporarily.

 

Drop it in dry uncooked 

rice with closed container for 24 to 48h to remove humidity, like you would do for a smartphone. It 
should work again. 

What other software than Arduino Software can I use to control the TDL device?  

The IDE software provided by Arduino is specifically designed for Arduino and Arduino-compatible 
devices and provides an easy interface to beginners and advanced users. However, some users might
