Installing Arduino (Mac and Linux) Get started by visiting the Arduino.cc website and downloading the matching IDE for your operating system. As of April 2014, we suggest using v1.05 as 1.5 is still in beta. If 1.5 is no longer in beta by the time you read this, you can try it out!

Key idea: add two quantities with opposite temperature coefficient with proper weightingÆthe resultant quantity exhibits zero temperature coefficient. Eg: V1 and V2 have opposite temperature dependence, choose the coefficients c1 and c2 in such a way that: Thus, the reference voltage V

The remedies include the use of large MOS transistors to address the first issue, the choice of an op amp topology for high supply rejec-tion for the second issue, and adding a start-up circuit to deal with the third.
