Fun with Arduino 41 Real Time Clock DS1307

The station platform clock of the previous video runs, but it shows a random time. We can add a Real Time Clock module to have it show the current time. Several versions of Real Time Clock modules are available. This video is about the DS1307 RTC, which can be had for under $1,-. Link to Fun with Ar...

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 39 - OLED display SSD1306

We're going to add an OLED display to the ultrasonic distance measurement of the previous video. Together with a battery it now becomes a fully handheld portable device. This is just for fun, the actual purpose is to introduce the OLED display ... once we have that up and running there's a whole lot...

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...
