Programming Questions / Has anyone programmed a MPS20n0040D-S Pressure Sensor?
« Last post by m6powers on June 06, 2018, 01:05:17 PM »
I am running an Arduino UNO with a SparkFun HX-711 Load Cell AMP. I am trying to find a good program to use
to get my sensor to read pressure and to check out out my connections. I had to Solder the HX-71 and need to make sure it is working. With this being my first go at programming, I am running blinded my my inexperience.
                      Thanks for any help!
I have a couple of 120v AC fans that came from old air hockey tables, they currently have a toggle switch to turn them on and off however I would like to be able to control there speed instead of it just being full on or off as they are quite noisy at max. I have limited knowledge with electronics and I don't typically mess with mains voltage but I was curious if this was possible and if so what type of switch I could use or what would be best. I would prefer a small switch similar to the one it already has but I would also be fine using a bigger one if needed.

Any suggestions are greatly appreciated.

Wiring Hardware Questions / Reviving the original Wiring (ATmega128a) board?
« Last post by westfw on March 15, 2018, 06:34:32 AM »
(How depressing; most of the Forum Messages in the last several years are spam.)

Anyway, the ATmega128a is fantasticly cheap these days (from China), and I had some interest in creating an old-style Wiring board aimed at hand assembly...
And it's pretty much working...

Website Questions / Micromag units of measurement for readings
« Last post by ZPMMaker on November 28, 2017, 08:34:45 AM »

I'm working with the MicroMag 3-axis magnetometer, as described at

The script provided there (which runs on Arduino) outputs three readings (mag field x,y,z) to serial output/USB.

However, the script doesn't say what units the magnetic field readings are provided in.

Does anyone know what these are?

Thanks in advance.  :)

General Discussion / auto/ manual wiring circuit diagram
« Last post by smsebna on September 23, 2017, 04:13:33 PM »
Hello everyone

I have a question about wiring circuit diagram.

I have one motor that turn right and left, with selector switch.

These are my steps:

1. If operator select auto mode, in1 is activated , so out 1 or out2 is activated, according to program of PLC, motor is turned to right or left.
2. If operator select manual mode, in2 is activated, so out3 is activated, and operator can select turn right or turn left the motor.
The problem is :

When operator turn left the motor, out3 connected to out1 reversely. And when operator turn right the motor, out3 connected to out2 reversely.

How I can fix these problems?
