Good day guys!
I just want to ask a question about on my final year project. Is it possible to power up the Arduino uno and sim800 gprs gsm shield using 12v 15 amps power supply through its DC barrel jack? I am also using a 2 way dc barrel jack splitter to it in order to power them both.
I am using the said power supply because I also need it to power up the PTC fan heater and a humidifier.
