Re: Electric motor project

Thanks. There is a breadboard power supply board in the kit but no instructions on how to use it. I'll have to email Adeept for them.

Electric motor project

Hello. I'm new to physical computing and am using this Adeept starter kit. This project is to run a motor. The 4 buttons control the direction and speed of the motor. The LED shows that the motor is on. I can't get the motor to run though. The program is showing that the buttons are working. I know ...

Hello. I've been looking into having OSMC on my Rpi and have found that it's on the latest version of Noobs. I wondered if you can swap between it and raspbian. If so how do I do this? Thanks.

Re: Use a PIR to start a video then disable it.

Thank you very much for your help. I would never of got the PIR sorted without your help. I played around with the second bit of the code so that a button push starts a second video.

Re: Use a PIR to start a video then disable it.

Hello. This is the code I am using. It does start the video as planned but I cannot stop the PIR detecting movement. import os import RPi.GPIO as GPIO GPIO.setmode(GPIO.BCM) GPIO.setup(4, GPIO.IN) while True: if GPIO.input(4): os.system("omxplayer -o hdmi /home/pi/output.mp4") Thanks.

Use a PIR to start a video then disable it.

Hello. I am doing a project with my grand children where a PIR is used to start a video. When that has stopped they push a button to start another video. The problem I'm having is that all the programs I've found to use the PIR have a while loop so the video keeps playing. Is there a command to stop...

Re: Resistors and physical computing.

Thank you for that. As I said I know absolutely nothing about electronics. If I wanted to buy some 330 ohm resistors for the Pi do I just search for 330 ohm or are there different types of them? I feel safer if I had what was recommended.
Thanks.

Any of the LED projects I've seen use 330 ohm. Will it damage my Pi if I use the 220 ohm? Can anyone recommend a really ...
