Automatically water your small indoor plant using Arduino + pump
Never mind I figured it out by myself. I did notice that connecting the resistor base to A0 did not do anything so I connected it to digital pin 2 and altered the code a tiny bit and everything works perfectly.
Great tutorial, but my transistor gets extremely hot and smells like it is burning. Any idea what's happening? I am new to electronics so forgive me if it is a simple issue but I just cant figure it out.
UPDATE: would you please add the following line in step 5:rm /var/local/wpa-roam.confThis is required sometimes to get a new pairing code.
Very Easy instructions...Thank u for Letting us make this project
The link to the original pairing instructions is broken. Can you update it in Step 7 (as opposed to putting it in a comment)?

Hi!Here, 1K prevented the pump to get enough current. I had to use a 220 resistor to make it work.
I made this - thanks a lot for the inspiration! But with me, the 1k resistor was too much, so it wasn't working. I changed to a 220, and then it worked. I hope this won't fry my arduino...
I need a program which can start a 5v relay automatically daily in 4 pm of arduino uno
Ah, I see what you mean about the Vin pin. But with a genuine Uno, the Vin pin appears to be connected directly to the incoming power supply with nothing in between: https://www.arduino.cc/en/uploads/Main/arduino-uno...But yeah, 3 liters per day is a lot. Best of luck!
Thanks for the info, I've updated the Instructable to reflect the 1k resistor.
I see that you live up to your name. But thanks for catching my mistake! I've updated the Instructable.
Sorry you fried your board! You weren't trying to run the motor directly off the board itself, right? This design already uses a transistor. That being said, people more knowledgeable than myself are saying to use a 1k resistor in series between the board and the base pin of the transistor, so make sure you do that.
