Guest prestost Posted August 9, 2013 Report Share Posted August 9, 2013 Hello there.I'm a newbie in electronics and don't really know how to do things. Therefore I need some help.What I want to do is to have a thermometer, and when the temperature reaches 25°C I want a small strobe to be activated.It maybe sounds kinda easy to you guys, but I have no idea how to do this and what to buy. I've looked on buying a rasberry PI but a friend just told me that buying a micro-controller was going to be cheaper. I don't want to spend so much money as this is a little bit just for fun. Maximum maybe 100$. Thank you for your helpBest regardsprestost Quote Link to comment Share on other sites More sharing options...
redwire Posted August 16, 2013 Report Share Posted August 16, 2013 Try an Arduino with a breakout board for the power supply, temperature sensor, and led (strobe). Do you know anything about soldering or programming? Quote Link to comment Share on other sites More sharing options...
