Sensor Shield V5.0 Digital Analog Module Arduino Duemilanove/UNO DA I/O Board

in this video we're gonna talk about how to power your dwee no censor shield now there are four possible scenarios when powering your sensor shield and it's gonna depend on whether or not you have this pin connected here and whether or not you have an external power supply connected we're gonna test out all four scenarios first with the pin off so this is not connected and with just the Arduino connected to the 5 volts power supply this one right here gets 5 volts and this one right here gets nothing so whenever the Arduino is just purely connected to a 5 volt power supply only this section is gonna give 5 volts this section right here is not gonna get anything so what is it gonna look like when you have the 5 volt power supply any external output so again we'll do the same test so this side still gets the 5 volts and this side gets the 8 volts so this one's gonna get powered through th
