About: I’ve been in IT and Software Development forever! My real passion though is where Software and Industrial Design meet. Especially micro-controller based gadgets and map reading for dummies pdf Printing.
It can work with a micro-controller like the Arduino or it can be programmed to work on its own. You can also easily create and upload your own code and this makes it hugely powerful and flexible. The ESP8266 was launched in 2014 and is rapidly growing in popularity. There is only one ESP8266 processor but it is found on many different breakout boards. These all differ in terms of which pins are exposed and the size of the flash memory etc. These breakout boards have evolved rapidly over the years and there is a lot of information to be found on the web. This is both a blessing and a curse as some of the advice is outdated or just plain wrong.
As a result it took me 3 days before I could get it to do anything! Some people are lucky but for me it was a battle to get anything working. At times I thought I had broken it but with some perseverance it always came back to life! I’ve finally got it singing and dancing and it turns out to be easier than I thought! I’ve consolidated all the useful info I found into one place and I thought I’d share this in an instructable. This will hopefully get you quickly up and running with all the basic functionality that you’ll need. In this instructable were are looking at the ESP-01 breakout board.
It can connect to your router and work as a client or it can be an access point itself or both! 2 digital pins that can be used for input or output. Eg: to drive LED’s or relays. These pins can also be used for PWM. Other versions have more pins exposed. For example the ESP-12, which is a good option if you need more pins. With this demo you can start your own home automation project and control it from the web!
A lot of sites recommend re-flashing the firmware and using various tools. You don’t need to do that just yet. We’ll be replacing the firmware with our own code. In another instructable: The Simple Guide to Flashing Your ESP8266 Firmware I show you how to revert it back to an updated factory version. If you’ll only be programming the ESP8266 with your own code – as we will be doing in this demo – then you don’t need factory firmware. We’ll be using the Arduino IDE as a programming tool but we don’t need an Arduino itself.
The ESP8266 has all the functionality we need. Note: that after uploading your own code, your ESP8266 won’t respond to AT commands any more. Your code has replaced the firmware. Using your code and the ESP8266 library in the Arduino IDE you’ll have access to a richer set of commands. You can restore the firmware on the ESP8266 to go back to AT commands if you wish. See my other instructable: The Simple Guide to Flashing Your ESP8266 Firmware.
The ESP-01 is more robust than I thought but you should set it up properly, especially if you’re using it with a 5V USB to Serial Programmer or micro-controller, otherwise you may fry it! Some come with a jumper to switch between 5V and 3. If you have an ESP8266 with a built in USB port then you don’t need to go through any of this hassle. The Wemos D1 Mini is a good alternative. A good power supply seems to be a crucial aspect for the ESP8266. A breadboard power supply is really useful, especially when you’re dealing with mixed voltages. The one shown here supplies 3.
This is useful as a quick means of summarizing the total area of significant change in a given statistical comparison. Whilst I’m asking questions: why the ESP, the seven philosophical reasons I list above are probably not enough to help you decide if Pine is the right mail and news program for you.
