  • To be safe - construct interface - 3v output to 5 v system - transistor amplifier - a CMOS chip will switch , whilst output from 5v to 3v - resistor network , voltage divider . Get it working even if badly and slowly - then adjust

  • I had no problems - but then I WAS on Hainan , did have Chinese friend - and he used his chinese credit card , which I repaid on . Took five days Part of problem - the chinese ARE learning english , has to be shipped by container and ""yours"" is a small item .
