    Fun with Arduino - a Series of Introductory Videos

    I can't imagine the ultrasonic detector to be accurate enough, or be able to measure train distance at all when facing the nose. I don't know what software you use to control your layout, but usually control software already have built in options to decide allowed tracks based on train lengths...

    Fun with Arduino - a Series of Introductory Videos

    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...

    Hantek 6022BE Oscilloscope Software Overview

    Hscope for Android - Hantek 6022BE For those who are interested ... a video about the Hscope for Android app that can be used together with the Hantek 6022BE USB scope module, and with many other hardware modules. Link to Hscope for Android - Hantek 6022BE

    Fun with Arduino - a Series of Introductory Videos

    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...

    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...

    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...

    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,-...

    USB Configurable 16 Channel Arduino DCC Servo & Accessory Decoder

    ArCoMoRa 5 - Servo with Additional Output Ports to Switch Electrofrog 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...

    USB Configurable 16 Channel Arduino DCC Servo & Accessory Decoder

    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...

    USB Configurable 16 Channel Arduino DCC Servo & Accessory Decoder

    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...

    USB Configurable 16 Channel Arduino DCC Servo & Accessory Decoder

    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...

    Fun with Arduino 37 Control a NEMA 17 Stepper Motor with Easy Driver Several driver circuits are available to control a more powerful stepper motor like a NEMA 17. In this video the EasyDriver is used, but the software is applicable to any driver with Enable, Direction and Step inputs. Link to...

    USB Configurable 16 Channel Arduino DCC Servo & Accessory Decoder

    Part 1 - Download & Install Windows Software Model railroad hobbyist friend Nico Teering took the Arduino DCC decoder software to a whole new level. A wealth of functions are combined all into one Arduino sketch for multi-purpose DCC control of 16 pins. In a joint effort with Sergey...

    Fun with Arduino - a Series of Introductory Videos

    Fun with Arduino 36 Store Data in Non Volatile Memory EEPROM Because a stepper motor does not know where it is after startup, we need a way to find out where it is. We used a zero find routine to rotate the motor until a sensor is triggered. But suppose we were able to store the last position...

    Fun with Arduino - a Series of Introductory Videos

    Fun with Arduino 35 Turn Table Control with a Stepper Motor Now that we can find the zero switch or -sensor, and we know how to position our application by rotating an exact number of steps, we have all ingredients to build say a turn table, or a translating table or an elevator. We use a...
