I`ve just made a garage alarm using the same PIR sensor. I tested it for a week and got one false reading. Might of been the sun light coming through a window. I`ve added a 10k ohm pull down resistor to the 5 volt signal just in case that caused it. I also use a window screen wiper motor to pull an insulated cover over in the greenhouse to keep the plants warm at night and keep the lighting right. :)

Hello, I've a question. In many wiring schemes I see online, the xy160d is also powering the Arduino itself. I can't get that to work. Have i misunderstood something
@TheOldKid3 ай бұрын
A question for anyone. I was using an l293d as dual h-bridge running a mg996r servo and a motor from a powerwheels grave digger with flysky. Worked fine until smoke and fire. I realized later one of the wires from my main voltage supply had broke loose and shorted across the l293d. I ordered the same driver Rachael uses in this video and cannot seem to get it to work. The l293d had EN1&2 , 5v, input 1&2, output 1&2 and main power input. The xy160d has same type pin labels. The only thing that i see possibly different is l293d has EN1&2 the xy160d has PWM1 on docs where board says EN. Arduino pins 5&6 went to input 2&7 on l293d and arduino 9 went to transmitter. Could it be that with the new board i need a pwm signal from the arduino to the EN/PWN on the driver along with another pin from arduino to transmitter? Im no programmer by any stretch. Im a fabricator and welder. I can imagine to everyone in the microcontroller world this is a simple no brainer but im old, melt metal. If i cant straighten it with a sledge hammer or welder i have a torch. This is the last piece to my puzzle to have my project operational so all help, any help or advice is greatly appreciated

Hey, I am going to be building auto doors for my smallish shelf unit. I now have 2 ideas as to how i would like to do it, after seeing this video. I watched a video on using a 2 button idea and thought that would be fantastic but, now i am thinking 2 pir's or motion sensors. i have not drawn up any plans at the moment as i went through some medical things. I do like to play with led lights strips and have them nearly everywhere in my room lol. Is there any chance you might be able to do a tutorial on making something like that Pretty Please ? And Yes, i have to agree, this tutorial was awesome as.
