This is a historical beginner build for a dedicated physical button that sends a press event over Wi-Fi to an automation service. The 2015 guide estimated about $10 for parts, but that is not a current price: it describes a project to assemble, not a ready-made product. Its “no coding/soldering” promise describes the intended beginner experience; setup still involves firmware, project-specific device files, Wi-Fi credentials, IFTTT configuration, wiring and enclosure work.
What the button does—and what the old guide assumes
A momentary tactile button connects the ESP8266 development board’s D2 input to GND when pressed. The board’s firmware then uses Wi-Fi to send an event so a configured automation can respond. The original tutorial describes an IFTTT account, Maker service, event name and key, plus firmware and device-software setup. Those are instructions from 2015, not confirmation that the same Maker workflow remains available or works unchanged. See the original Hackster project.

Current IFTTT documentation describes Applets and current service connections; its own getting-started guide says “No coding is required” about using the automation platform, not about maintaining compatibility with this older device project. Check the current route for the service you intend to trigger before building around legacy Maker key and event steps. IFTTT’s getting-started guide and Applet creation instructions explain the current platform concepts.
Parts and tools to plan for
The project’s historical estimate was about $10, as stated by the SimpleIOThings/Hackster tutorial in 2015. It is not a present-day parts quote; the companion page notes that prices change. No current total is established. The build calls for an ESP8266 development board, not a bare ESP8266 chip. Check the board’s pin labels and USB connector before buying or wiring.
#1 Best Overall
- Not only it is easy to program for this controller by using the CP2102-USB interface,but also unnecessary to press the flash and reset buttons before each flash operation.
- NodeMcu is an open source Lua based firmware for the ESP8266, ultra low cost wireless modules, development boards for rapid prototyping, integrated with ESP8266 chips.
- The ESP8266 has powerful on-board processing and storage capabilities, and can be integrated with sensors and other application-specific devices through its GPIOs.
- It is compatible with Arduino IDE,works great with the latest Mongoose IoT/Micropython.
- Modern Internet development tools can use the built-in API to instantly put your idea on the fast track.
- ESP8266 development board
- Momentary tactile push button
- Female-to-female jumper wires
- Micro-USB cable (the project list specifies a 10-foot cable)
- USB wall charger
- Project box
- Flat-nose pliers, hacksaw and super glue for the enclosure work described by the guide
These are the parts and tools listed in the SimpleIOThings companion build page. The cable length is the tutorial’s listed item, not a universal technical requirement.
How the build is organized
1. Check the automation route first
Create or sign in to an IFTTT account and identify a currently supported way to trigger the action you want. The 2015 instructions use Maker, an event name and a key. Do not assume those legacy credentials or steps remain usable; current IFTTT features and service connections may vary by plan or service. The old article names notifications, SMS, email and phone calls as possible actions, while current IFTTT examples include notifications and smart-home actions. Availability depends on the connected service and current account terms, and the sources do not establish that every old example is currently offered.

2. Prepare the board software
The historical tutorial names ESP8266Flasher and LuaLoader, and instructs builders to load firmware and project-specific device software, then provide Wi-Fi credentials and event/key information. These are period-specific tool references. Follow the project page for its exact files, but verify that those files and the chosen IFTTT trigger route are compatible with the board and services you have now; the available sources do not establish ongoing maintenance or present-day operation.
3. Wire the physical button
With the board unpowered, attach two jumper wires to the button as directed, making any specified adjustment to the button prongs. Connect one wire to GND and the other to D2 on the development board. Pressing the momentary switch should electrically join those two connections. Confirm the actual board’s GND and D2 labels rather than relying on a pinout for a different ESP8266 board.
Rank #3
- Built-in Micro-USB, with flash and reset switches, easy to program
- Arduino compatible, works great with the latest Arduino IDE/Mongoose IoT/Micropython
- Data download access to the website: http://www;nodemcu;com
4. Fit the components into the enclosure
The guide has you make openings in the project box for the USB cable and button wires, then secure the button and close the box. Its listed tools include pliers, a hacksaw and super glue. Work carefully when cutting the enclosure, keep the board unpowered during wiring, and ensure the cable and button leads are not pinched when the box closes.
5. Power up and check the event
Connect the board by USB to the charger, allow it to join Wi-Fi, and press the button to check whether the configured event produces the intended action. This is the guide’s verification sequence; no independent build, compatibility test, uptime or response-time result is established here.

Physical button or IFTTT’s phone Button widget?
IFTTT documents a Button widget that triggers an Applet from a phone home-screen button. It is a software alternative, not the same device or a feature-for-feature replacement for a dedicated ESP8266 button. IFTTT’s Button widget page and Button-to-IFTTT connection page describe that phone workflow.

| ESP8266 DIY button | A separate physical button | Hardware sourcing and assembly, board firmware and device files, Wi-Fi and a currently compatible automation route | Requires a build and its device/service compatibility must be checked |
| IFTTT Button widget | A button on a phone home screen | IFTTT app/widget and a connected Applet; current availability may depend on the service or plan | No separate hardware build, but it relies on having the phone available |
Choose the DIY route if the point is to place a dedicated button somewhere convenient and you are prepared to confirm the older project software and trigger path. Choose the widget if a phone tap meets the need and you want to use IFTTT’s documented current interface instead of assembling hardware.
