We are pleased to announce the next class in a series of simple, ham-related, electronic projects, presented by one of our members, Dixon Barthel K3WNS. The project for this session is “Arduino – Real Time Clock and Frequency Counter” . Click here for outline (Coming Soon).  

For those who have missed the previous sessions, we talked about the basics like Ohm’s law, inductors, capacitors, transistors, and the like. All the notes from those sessions are available. We also played with Arduino and PIC projects. The previous class introduced Arduino code and simple circuit. Other classes discussed simple, practical code oscillators, the workings of an ammeter and a voltmeter.

This class is on Wednesday, February 7, 2024, Currently (though we may change) the meetings are held at the Department of Emergency Services at 2220 Ady Road, Forest Hill, MD 21050,  just north of Conowingo Road (see the tall tower and you’re there). We’re meeting in room 106. Just ask the attendant where to go and log in. We meet every other Wednesday at 6:30pm in the evening and go to about 8:30pm. No charge.

For your part, you’ll need an Arduino board, breadboard, some LEDs, some resistors, and some capacitors. You’ll also need a power supply to provide 9-12 volts to your board.

We just want to help folks know how to do stuff. Attendees’ may be (but do not have to be) be a member of Harford County ARES/RACES, or can hold or are interested in getting an amateur FCC radio license. There is no fee for the class, but there could be a small fee for parts.

In order to attend, please contact K3WNS Dixon Barthel , K3WNS@gmail.com first, via email, for more information and prior to attending .
