A simple breakout board of ESP8266 on breadboard can do most of NodeMCU work. Also need a PL2303 USB-TTL programmer Most wifi embedded project will not have too much input and output resource to let the user enter the wifi SSID and password info, so we normally config this via...
All the relevant items can be purchased from www.electrodragon.com! items used in here including: ESP-07 with on board status LED (ESP-12 LED will not work for arduino blink sketch) ESP breakout board CH340 USB-TTL programmer breadboard and a few jumper wires. You can find the flash tool on this page. Flashing options in the...

You can find the arduino library in the product link: https://www.electrodragon.com/product/ws2812-neopixels-ring-leds/ https://www.electrodragon.com/product/8-led-ws2812-5050-rgb-led-stick-board/ From the example, run "standtest" sketch, follow the instruction to setup for the board, and it will show all the standard effects: The wiring should be Din - pin6 of arduino, VIN - 5V arduino, GND - GND arduino. And here is...
You will need firmware, NodeMCU flasher to flashing the firmware, and Esplorer GUI to test the firmeare. All the tool you can find it here. Wiring as below use a PL2303 USB-TTL here: TX-RX, RX-TX, GND-GND, 5V - VIN (more…)
Combined two items to together, the module from AC power source to 5V and 3v3: AC-DC AC 85-265V to DC 5V Power Module AMS1117-3V3 Regulator Module This is just a rough idea, you can make it much better. ( for example, Add some hot glue between the two broads to fix them.)
We are new to the quadcopter, it is a lot of fun, but the video quality turn out to be really normal. So there are basic problems which need to be aware when you choose a cheap one of this: PZT (Pan-tilt-zoom) camera, the camera must be able to against the...
The NodeMcu development board is sold out recently, not sure when the new stock will arrive. The development has some peripheral circuit to ease your usage, including USB-UART, USB5V-3.3V power supply, buttons, and lead out all the IOs. But you can still use the Wi07-12 standalone without the dev board, we...
There is already an official SDK running on Linux Lubuntu, very easy and simple to use. But now here we have the SDK environment transplant to Windows system via the software tool called cygwin, which allow you to create the linux environment in the windows, and we have the SDK running...
It is very easy and common to read the RFID card ID, which is the first 4 bytes of the data area, and used to identify the card holder. But also a lot of people ask if the RC522 can write a RFID card or not, the answer is yes,...
