The Arduino is a flexible platform for controlling all kinds of devices from all kinds of input signals. Here I demonstrate the most basic Analog Input — a voltage from a potentiometer — and…
I discuss some of the things I am learning in my robotics class. By converting sensor data to digital, it can be used to control the function of a microcontroller. The microcontroller can be…
The LeCroy WaveJet 324 Digital Sampling Oscilloscope makes it very easy to determine the frequency of a displayed signal. Of course….. RTFM is always a good idea, if you are an expert consultant who…
hi there back agin, i was abale to get some reading on my digital meter, and yes my analog meter was barely out of range, i got 100mA draw when the 4 lights connected,…
I demonstrate a digital range finder I made with the ultrasonic range finder module and a microcontroller.
Loading test of the Orbo motor v4. A pickup flat coil has been placed at 45° from the toroïdal stator coils. This output coil has been connected to a High Power Leds panel and…
Bar graphs are so last century. This is Century 21 ! The omnidigital error…er, era. If it don’t have numbers in boxes, it don’t have squat. So here I show how to adapt a…
Here I show the Little-Known feature of the Tek 2213A analog scope. Apparently not many people know how to display stored waveforms from these old analog scopes. The process is somewhat different from that…
* Will not work with all phones or usb battery chargers.* The protection diode is critical when used with digital meter for protection of usb devices seeing the residual panel voltage in the digital…
Very interesting observation while playing with bemf pulse motors (the idea’s to make enough thrust from magnetic pulse motor powered by 1.5v bttry to spin light generator, making 0.01more watt of power than spent). So, as we can see the bemf creating …
