Open Arduino Enter Your Project for a chance to win a grand prize for the most innovative use of Arduino or a $200 shopping cart! The Birthday Special: Arduino Projects for Arduino Day!

In the last two blogs, I described the issue I had. Electronic Diet Electronic Diet - part 2   I have a spare car that has an older model alarm system fitted just to provide remote lock/unlock. The car has central locking and uses a transponder key, so it's not that easy to steal, but the flashing LED right next to the ignition barrel does suggest it might make noises if you break in.   The unit was fitted when we first got it, and it allowed my wife to open the doors from the footpa ...

Electronic Diet - part 2

Posted by mcb1 Top Member Mar 23, 2018
In my first post Electronic Diet I explained the title   Okay so the title is a bit misleading. I'm not planning on consumming electronics, or removing electronics from my diet (no I don't eat parts) source https://favim.com/image/474959/     The plan  1. Check the current consumption of the unit. 2. Check to see if it can easily be reduced, and by how much. 3. Either fix it or replace it.     I've managed to find all the information about my fitted alarm unit. ...

I started diving into ESP32 and MongooseOS back here. ESP32 and Mongoose OS - Intro   my first application attempt was realtively painless ESP32 and Mongoose OS - First Application   It all seemed too easy until I struck some unexplained issues ESP32 and Mongoose OS - Issues     Now that I have discovered the problem was with the application, I tried importing another temperature application. I'm rather happy to report that this one worked flawlessly.   So I ha ...

2017 Activity

Posted by mcb1 Top Member Jan 8, 2018
There were a couple of posts by shabaz and dougw about their posts during 2017. My 2017 Projects/Activities 2017 Summary of element14 Activity I was thinking at the time that it was a large list and far more than I had achieved.   2017 has been a mixed year for me. We have been dealing with the aftermath of our motor vehicle accident (June 2016), and the fallout from that. This has had a significant impact on my time and resources, and we've tried to compensate by undertaking more e ...
I have been dipping my toes into ESP32 and MongooseOS. ESP32 and Mongoose OS - Intro ESP32 and Mongoose OS - First Application   These posts hopefully help others, and if nothing else will assist with keeping track of where I'm at.   I had great success with the NeoPixel, although it was simply loading someone else hard work, and then tweaking it. Spurred on, I decided to try a Dallas Temperature sensor App. There seems to be a couple and I wanted to use the one based on C.  ...
In my previous post ESP32 and Mongoose OS - Intro  I showed how to connect to an ESP32 using Mongoose OS and setting up the WiFi.   In this post I want to do something more useful, and control NeoPixels.   yesterday I showed Flashing the device with either of the inbuilt demos, but you can simply select the Com Port and Platform and then close the window by hitting done.   Connection Issues I had some issues yesterday when I was playing around, and today I decided to try ...
A few weeks back I was introduced to ESP32's and Moongoose.   The guy running the presentation had been using ESP8266's and some custom code, but had been following Moongoose and its progress. He felt it had matured and with the ESP32 device support it was time to venture in.   ESP32 It seems there are a huge variety of boards out there, but you do need to be sure it includes the ESP32 rather than the smaller ESP8266.   I purchased two different types LOLIN32 Lite USD$4.90&# ...

Rear View Camera ver 2.0

Posted by mcb1 Top Member Dec 21, 2017
Back in 2015 I created a rear view camera for our caravan.                Photo source Three Minions (me, myself and I)   Rear View Camera   While ver 1.0 was functional, it wasn't really useable for a number of reasons.     The height was fine, but it did require something to stop it moving around. I had looked at sticking it down, tying it down, and those suction cup things. Because we need the sp ...

Jumper Cables

Posted by mcb1 Top Member Nov 1, 2017
Jumper Leads All of my vehicles have a set of jumper leads, for that day when you accidently leave the lights on, or someone else that needs a bit of spare energy. The leads are usually purchased from the local retailer "where everyone gets a bargin" and are less than $20 and in a bag so that they keep the car clean.   I'm well aware that the insulation looks like it's designed for 1,000,00 volts, but bigger size always means better ... right I know they aren't high quality but the othe ...

ATTiny Fuse Resetter

Posted by mcb1 Top Member Oct 14, 2017
The other week I was playing with a Digispark clone, and it turns out that the suppliers have not programmed them correctly.     Let me explain When Erik created the Digispark, he wanted to use all 6 pins of the ATTiny85 for I/O. Because there is a bootloader, you can program them as per any other Arduino (slight differences but essentally the same), rather than having to use an ISP programmer.   The reset pin has been disabled via the fuse setting, and therefore becomes a norma ...

What went wrong

Posted by mcb1 Top Member Sep 14, 2017
My electronics skills get called upon for all sorts of things.   What Some years ago a close friend asked if I could help with some LED tailights he was fitting to his Hotrod. He had purchased some american made units that had allowed for tail, brake and Indicators, but he was going to have two on each side. They were rectangular and had one section for Indicators, and hence it only partially illuminated and looked strange.   The question that came my way was there a way to make t ...
Some time ago jw0752 made contact with me and wanted to send me some of his meter probes. He's been keeping the community up to date as he makes changes to the original concept.
