Cheap Controls
Hosted by Ed Malloy · EN
This podcast is for Electronic DIYers that enjoy Electronic Control Applications and use Arduinos, Nextion Displays, and ESP32 circuits. We try to through in a little humor to make the videos a bit more entertaining.

Apr 17, 202000:04:10Tap to summarizeI published two videos this week. The first one is on sending a value to the Nextion and setting the decimal point for a float item. The second video goes over the basics of using the built in eeprom on the Nextion Display. I also discuss upcoming projects or my lack of up coming projects.
Transcribe →Cheap Controls Episode 9, Pt 2 Floats and Arduino control of Nextion dual action button
Apr 11, 202000:06:07Tap to summarizeI published two videos this week. One used the dtostrf command. This video made me look into arrays more. I discuss changing a dual state button based on the LED output. I implement timers to change the LEDs on a 2.5 and 5-sec interval. When the lights change I send the current output value to the Nextion. I also show how to change the LEDs by pressing the button on the Nextion and sending a signal to the Arduino. I then reset the timer so the LED will stay in that state for the interval configured by the Arduino. This was a fun project to make. I also discuss upcoming projects and my cruise vacation I am taking this week.

Apr 3, 202000:04:50Tap to summarizeI talk about the videos that came out this week and videos that are coming soon. I also discuss my current projects and what else is going on.

Mar 27, 202000:06:53Tap to summarizeThis week we finish the get command by discussing timing and parsing. We answer a question and discuss future projects.
Transcribe →Cheap Controls Episode 6, the get command, timing explained
Mar 20, 202000:06:27Tap to summarizeIn the episode, I the one and only Ed Malloy discuss this past week's videos. Answer a lucky listeners question and talk about the direction Cheap Controls is heading. We published two videos this week. In the first video we discuss the timing involved with a get request. We go into more than the effects of the get request. This video can be applied to other aspects of timing in the Arduino. Although this is in the Nextion wheelhouse this video is more related to the Arduino. When you are working with timing and asynchronous versus synchronous things can get a little confusing. We want to talk about some advanced topics we feel will help you with not only this project but other projects with similar coding situations. The second video finishes the timing aspects of the get request. We eliminate the final delay by using an "endswith" command. I discussed this a bit before because we considered using a "readuntil" command instead but found the command less straight forward than the "endswith" command. We wanted this video to focus on the timing and not get even more outside the bounds of the get command than we already were

Mar 14, 202000:07:35Tap to summarizeIn the episode, I the one and only Ed Malloy discuss this past week's videos. Answer a lucky listeners question and talk about the direction Cheap Controls is heading. We published three videos this week. The first one was the final in series that had Nextion control a pulse width modulated output on an Arduino. We had two separate sliders control two individual LEDs. The video was #12c. The next two were the start in the get command series. The first was a simple setup video. We went over the HMI Nextion configuration and programmed the Arduino with the initial code. This was more of a refresher video for any longtime followers of your videos. The second video showed the Arduino sending the get command and the data that is sent back from the Nextion. We did not get into the parsing of the data. We felt it was important to split this video up and go into as much detail as we can. As always, we avoid using the Nextion.h library.
