Thank you Gert, it's great to have your help

Hi, I haven't used my Gertboard for a while, everything seemed fine with it when I used it last. Unfortunately one of the resistors appears to have popped off near the LED's. I'm sure I could solder a new one on (despite having limited experience with SMD). I was doing the research and before I buy ...

Hi, I would like to clear the terminal window to display sensor readouts.

I used to use console.clear on VB.

Thankyou very much, I'm new to electronics so it's been quite difficult to comprehend the relationship from the code to physical elements. Non the less it's been exciting and I have only blown one fuse so far

I'll have a good go now and hopefully just post thankyou very much in a while

Doe's this help me with the gertboard motor controller?

I'm approaching my deadline now, if you could supply the lines of code to have the motor run at a constant level then I would really appreciate it

dawson345

I'm not sure how to do this still, I am not familiar with PWM I just want to be able to have a process that runs the motor at a constant level. Would anyone be able to help?

dawson345

I was just wondering how to run the motor controller at a constant level for a duration of time.

I'm coding in python using RPi.GPIO, I'm coding in python.

Any help would be great

I'm using my gertboard to control a motor based upon a distance sensor. The process is as follows- 1. Motor Starts 2. Ultrasonic Sensor Reads distance until <20cm is read 3. Motor Stops I've used threads before in Visual Basic but lack the knowledge of how to do this in Python. Any help would be gre...

Thanks Gert.
I have the ultrasonic distance measure operating correctly now. It's a great tool, now to program that motor controller!

Really enjoying using your product.

There are resistors in place. 330ohm and 470ohm. The device worked through the pi but I was checking the correct grounding pin, where is it? Doe's it matter which I use per circuit? Ground is common to all voltages so you connect a ground connection for 5V or 3.3V devices to the same point. You will...

I'm unsure where to ground a 5V circuit on the gertboard.

Please advise, this is the guide I followed to operate my device on the pi.

Hi guys, I'm making a small buggy with sensor modules (Ultasonic Distance Sensor etc) for a university project. I have tested the sensor module using this guide- http://www.raspberrypi-spy.co.uk/2012/12/ultrasonic-distance-measurement-using-python-part-1/ I am unsure of how to link it correctly to t...
