Worst case scenario, you can use a tool like hwinfo with the option to log to file the measurements and run it in background, and every few seconds you parse the log from hwinfo and extract the info you want. There's freeware/open source tools and some info is available through windows api. The typical TMP36 temperature sensor’s operating range is (-40☌. Hi ive been trying to find some solution on how to read my arduino using C (visual studio - VB.net) i have the code made for my arduino to display the temp on two 7-segments and works 100 fine and i made it print the temp in decimals så the serial monitor for arduino reads the temp and that works well too. It’s got a linear voltage output response with a slope of 10mv per ☌ and an offset voltage of 0.5v on the output pin. The benefit is you can also use the 5v from USB cable to power your board.Īnyway, from this point you can write a small application that reads the temperature or fan speeds from somewhere and formats it into some format your arduino understands, sends it through the serial port. The TMP36 sensor is a very popular temperature sensor that can easily be used with Arduino using the ADC analog input pin. You can buy USB to Serial converts that directly output Serial TTL (the 5v version that works directly with microcontrollers), here's examples: Microcontrollers output 5v for 1 (or whatever the voltage the micro is powered with), so if you want to connect directly to the PC, you need to convert this 5v and 0v to -12v and 0v, using a transceiver chip.Īn example of such a chip is MAX232 and here's a schematic which powers the chip from the serial port and converts the negative voltages to 5v : Serial ports use a negative voltage for digital "1" and no voltage for 0. If your pc no longer has serial ports, you can buy a usb to serial adapter cable / device which creates a serial port. Modern computers may or may not have serial ports. The easiest way is probably to have the PC program send whatever text you want the LCD to display over serial. Then, an application on your PC can periodically send the info to your Arduino, which then displays it on screen. The easiest way to connect your Arduino to the PC is through a serial port.
