Hi, I am a brand new guy for Arduino. I have just read about it and have zero experience with the hardware. However, I have done projects before with other micro controllers, so I think that it’s going to be fine. At this point my whole purpose is to use Arduino to build a Bluetooth enabled device that measures air temp, barometric pressure, engine temp. The device transmits data via Bluetooth to an Android powered cellphone or tablet. I think that the device will consist of a minimum hardware as follows:
I would like to check with the experts here to see if anyone have a comment or recommendation for my minimum list, since I am new and may have overseen something. I appreciate any hint.
that bluetooth module is surface mount, so you’ll need to either solder leads to the pads or find/design a board for it. if you’re looking for a quicker hack, i’d go for one of the modules on a breakout board.
the TMP102 reads up to 85C, i suspect for measuring engine temp you’d need a higher maximum? you might consider using a thermocouple with a thermocouple amplifier. try googling thermocouple arduino and you should find some nice ideas/products.
also make sure you’ve got some header pins to solder onto your arduino, the pro doesn’t come with any pins populated. female are more convenient for jumper wires, but you’ll want male pins to connect the FTDI breakout board, so i’d suggest grabbing both if you don’t have any.
