Re: Hantek 6022BE Oscilloscope Software Overview

Well .. this is only partly true ... actually a sine wave can be represented by just 2 samples. But of course the higher the sample rate the better ... but also the more expensive.

Fun with Arduino 40 - Station Platform Departure Display with Analog Clock

In the previous video we attached an OLED and we saw how to display a text and some lines. In this video we take this a step further, we'll make a station platform train departure sign with a working analog clock. Via digital inputs a selection can be made of 6 different messages to display. This ca...

Hantek 6022BE Oscilloscope Software Overview

An oscilloscope is an invaluable tool to any electronics hobbyist. They can be had from a bit over $200 up to multiple thousands, dependent on specifications whereby max measurable frequency is an importand price factor. If you don't need to measure frequencies over 20 MHz a portable USB scope with ...

Fun with Arduino 38 - Ultrasonic Distance Measurement with HC-SR04

The HC-SR04 is a sensor that has a little loudspeaker and a little microphone via which the distance to an object can be measured. It's ultrasonic, humans can not hear it. Don't expect super high accuracy of this less than $1,- costing device, yet I was pleasantly surprised to see that measurements ...

Re: USB Configurable 16 Channel Arduino DCC Servo & Accessory Decoder

MARDEC software has the option to switch 1 or 2 ports in sync with operating a servo. The main application for this is to switch polarity of electrofrog turnouts. The video shows how to configure the one or two extra outputs. Link to ArCoMoRa 5 - Servo with Additional Output Ports to Switch Electrof...

ArCoMoRa 4 - DCCnext - Configure and Tune Servos

ArCoMoRa 4 - DCCnext - Configure and Tune Servos We're going to attach a servo to the DCCnext or Arduino and configure the MARDEC software to control this servo. To make the application work the first thing to do is tune the 2 servo angles for the DCC ON and OFF state. Maybe we also have to inverse ...

ArCoMoRa 3 - Double Port Accessories

MARDEC software has the option to switch 2 ports via 1 DCC address. A 'double flash' comes in very handy when for instance we have 2 inverse blinking lights, like with a railway crossing, A 'double one shot' is used to switch a solenoid turnout that has two coils. One port gives a pulse when the DCC...

ArCoMoRa MARDEC - Configure an output port to swith an accessory on/off.

ArCoMoRa MARDEC - Configure an output port to swith an accessory on/off. Now that the MARDEC sketch is uploaded to a DCCnext or to an Arduino, we can start to configure the 16 available ports. In this video we are going to configure port 1 to become a standard on / off accessory signal that we want ...
