Re: 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 digital...

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 ...

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 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...

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.

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 we moved to in memory and read it our after startup? The good news ...

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 Tuning sketch to determine the number of steps for every stop position...

Now that we can find the zero switch or -sensor, we can start to position our application by rotating the motor an exact number of steps. No matter if the motor has to make 97 steps or maybe 144668 ... as long as the motor torque and the driver electronics voltage and current suffice in order to not...

Fun with Arduino 33 Find Zero Switch or Sensor

A stepper motor does not know where it is after power up. If we want to use a stepper for accurate positioning, we first have to define its ‘zero’ point. This can be done by slowly rotating the motor until a sensor or a micro switch is activated. In this video we'll add a zero find routine as a prep...
