Fun with Arduino 40 Station Platform Departure Display with Analog Clock

ImageSeptember 23, 2019September 25, 2019 RudyB5 Comments

Now that we have the OLED screen working (see previous video) we can do something fun with it for an HO model railway: a station platform train departure display, with an analog clock that really works. The 128×32 pixel display is just a little bit on the tall side for HO scale, but it doesn’t […]

Fun with Arduino 39 OLED Display SSD1306

ImageSeptember 9, 2019September 9, 2019 RudyB2 Comments

We’re going to add a 128×32 I2C (4 pins) OLED to the distance measurement unit of the previous video to show the distance measured plus a bar graph. An Arduino Nano will be used this time, mounted on a breadboard. Together with the ultrasonic unit, the OLED and a 5V USB battery pack we have […]

Fun with Arduino 38 Ultrasonic Distance Measurement with HC-SR04

ImageAugust 19, 2019August 19, 2019 RudyBLeave a comment

The HC-SR04 is a nice little less than $1,- device that can be used to measure distance. It contains a loudspeaker and a microphone. When we send a pulse to its trig input, it will output an ultrasonic (40kHz) sound burst. It then measures the time it takes for the echo to return. We can […]

Arduino Experiment LED & Switch Panel

ImageJuly 27, 2019July 28, 2019 RudyBLeave a comment

A couple of people have been asking about the schematic of the LED & Switch Panel I use for the I/O with many of the Arduino videos. The switch box contains: 6 LEDs 2 push buttons 2 toggle switches 1 potentiometer 1 rotary encoder The image shows the drawing. The KiCad file is available for […]

Fun with Arduino 37 Control a NEMA 17 Stepper Motor with Easy Driver

ImageJuly 8, 2019July 8, 2019 RudyB9 Comments

Some applications may need a stronger stepper motor, one that can deliver more torque. The picture shows a NEMA 17 stepper. It’s a form factor (it means the size is 1.7 x 1.7 inch) in which a range of motors with different specifications is available. They are widely used in (DIY) 3D printers and NC […]

Fun with Arduino 36 Store Data in EEPROM

ImageJuly 1, 2019July 8, 2019 RudyB2 Comments

The turntable application of video 35 expects to first run the ‘find zero’ routine after startup in order to have a reference position from where step counting starts. Suppose after every move we could store our current position in non volatile memory? At startup we can now read the stored position out of memory and […]

Fun with Arduino 35 Turn Table Control with Stepper Motor

ImageJune 17, 2019 RudyBLeave a comment

With the ingredients of previous two videos, find zero and rotate an exact amount of steps, we’re able to control a turn table that has multiple stop positions. We need to find out how many steps it takes, counting from the zero point, to reach every position. We’ll use a separate ‘Tuning’ sketch for this. […]
