In this follow-up electronics tutorial, the bald engineer looks at how to pick pull-up resistor values.</p> <h2 id="show-notes">Show Notes</h2> <ul> <li><a href="https://www.addohms.com/pull-up-resistors">Pull-Up Resistor Tutorial</a> (Episode 15)</li> <li><a href="https://discord.gg/bS9H86x">AddOhms Discord Server</a></li> <li><a href="https://www.baldengineer.com/arduino-internal-pull-up-resistor-tutorial.html">Arduino Internal Pull-Up Resistor Tutorial</a> (baldengineer.com)</li> <li><a href="https://www.baldengineer.com/photos/chuck-norris-pull-resistors">Chuck Norris On Pull-Up Resistors</a> (baldengineer.com)</li> </ul> https://www.addohms.com/voltage-divider-regulator/ Sat, 14 Oct 2017 08:51:00 +0000 https://test.addohms.com/?page_id=72 <p>Previously, we looked at <a href="https://www.addohms.com/voltage-dividers">resistor voltage dividers</a>. Sometimes I get questions about using these instead of regulators. In this video, I show why that doesn&rsquo;t work. In fact, I go one step further and show that Zener regulators do not work either.</p> <h2 id="voltage-divider-as-a-regulator-show-notes">Voltage Divider as a Regulator Show Notes</h2> <h3 id="other-videos-to-watch">Other videos to watch</h3> <ul> <li><a href="https://www.addohms.com/voltage-dividers/">#13: Voltage Dividers</a></li> <li><a href="https://www.addohms.com/arduino-vs-raspberry-pi/">#7: Comparing Uno to Pi</a></li> <li><a href="https://www.addohms.com/linear-regulator/">#17: Linear Regulators</a></li> </ul> <h3 id="links">Links</h3> <ul> <li><a href="https://www.baldengineer.com/zener-diode-regulators.html">Zener Diode makes for a lousy regulator 3</a> (<a href="http://baldengineer.com">baldengineer.com</a>)</li> </ul> <p>In the episode, I am featuring the <a href="http://adafru.it/2471">Adafruit Huzzah ESP8266 breakout 4</a>. I highly recommend this board if you are interested in the ESP8266. It doesn’t have a serial to USB interface. However, it is far more reliable (and usable) than those worthless $5 8266 boards on eBay. (By Far.)</p>
