L298N Motor Driver Board – Drive Modes
Author: Doug Paradis
This article discusses how to connect the L298 motor driver in three modes: drive/coast, sign-magnitude, and lock anti-phase. Code examples will be for the Arduino Uno (or with small modifications the Mega2560).
The L298N is a dual H-bridge chip often packaged nicely on a PCB module. It is widely used on small inexpensive hobbyist robots. It has a maximum current specification of 2.0 A per channel with a peak current of 3.0 A per channel (from STI spec sheet). Each H-bridge can control one DC brushed motor.

DPRG Elections – 2021
It is time to hold elections for DPRG club officers. The election will occur during the DPRG virtual monthly meeting on January 9th, 2021 at 1:00 Dallas time (CST). This meeting is also the club’s annual meeting, where plans are discussed. It is very important that members vote and attend the January meeting. The club’s by-laws require that a specific percentage of members vote to make the election official.
A slate of candidates is proposed below. It is the same slate of officers that held office this past year. Any member can come forward and be added to the list of people considered for the various officer’s positions. If you want to explore holding office, an overview of officer duties can be found at officer duties. You can also get additional information by talking to an existing officer at any monthly meeting or RBNV (held every Tuesday at 7:30 PM). If you want to throw your hat into the ring, please let me know quickly at email “secretary at dprg dot org” so you can be added to the ballot.
Proposed Slate of Officers for 2021
President: Carl Ott
Vice-President: Clay Timmons
Treasurer: Steve Edwards
Secretary: Doug Paradis
Librarian: John Kuhlenschmidt
How to Vote
All members in good standing can vote. The list of members is at member list. If you are not on the list and you think you should be, the problem is most likely that you need to renew your membership. Contact “secretary at dprg dot org” if you need help renewing your membership.
Members can vote by emailing their vote to “election at dprg dot org” before the January 9th meeting. The email should contain the text “I vote for the proposed officer slate”, or “I vote for the following people for office”, or similar text that allows our volunteer election vote counter to determine your intentions.
Members can also vote in person or proxy at the January 9th DPRG meeting. If voting by proxy, you should signal your intention to vote by proxy by sending an email to the person that you are giving control of your vote and to “election at dprg dot org” so the person holding your proxy and the person tallying votes knows of your intention. The person holding the proxy must then vote.
