And now connect the ESP32/ESP8266/ Wemos D1 Mini, whichever module you want to use as a communication module. I'm using Wemos D1 Mini as shown in the Circuit diagram. After restart, click the File→ Example→ Tuya_WiFi_MCU_SDK → Start, you will get the pre-build/ demo starch there. Step 3: Now, connect the ESP8266 with your PC and

There you are! WeMos D1 mini (v2.2.0) Example/Test Sketch Well, now you might like to get and test some example sketch/code to begin the play. Here's how you can do that: Open "File>Examples". In examples of ESP8266 (or in D1_mini_Examples), just select the "Blink" program.
The Wemos OLED shield uses a 64×48 pixel monochrome OLED display that connects to the Wemos D1 Mini via pins D1 and D2, which double up as the I2C serial data and clock. It makes use of the Adafruit SSD1306 library for Arduino, so it is very easy to program.
In this example we will connect an RFID-RC522 module and connect to a Wemos Mini The microcontroller and card reader uses SPI for communication . The card reader and the tags communicate using a 13.56MHz electromagnetic field. (ISO 14443A standart tags) Features: MFRC522 chip based board Operating frequency: 13.56MHz Supply Voltage: 3.3V Current: 13-26mA Read […] NO: 5A(250VAC/30VDC), 10A(125VAC), MAX:1250VA/150W NC: 3A(250VAC/30VDC), MAX:750VA/90W 7 configurable IO, default: D1(GPIO5)
Here is the tutorial with parts and wiring. Wifi Fireplace w/Wemos D1Mini/ESP8266 | Automated Home Party. Because it is 5 volt, the ESP is 3.3 volt. You can probably use a opto coupler to get around this limitation. Have the D1 trigger the opto coupler then pass 5 volt through the opto coupler to the relay.
The ADS1115 device is a precision, low-power, 16-bit, I2C-compatible, analog-to-digital converters (ADCs) offered in an ultra-small, leadless, X2QFN-10 package, and a VSSOP-10 package. The ADS1115 device incorporates a low-drift voltage reference and an oscillator. The ADS1115 also incorporate a programmable gain amplifier and a digital comparator. These features, along with a wide operating
Shield for the Wemos D1 Mini board for learning development on the ESP8266 each with a high output led strip connected to a Wemos D1 ESP8266 using a Ledsee 16 channel PWM FET shield. PIR and Blynk trigger Example sketches to help connect a WEMOS as SPI MASTER to Arduino UNO SLAVE WeMos D1, D1 R2 & D1 mini Arduino Examples For more information, see the WeMos website or visit the forum . You can purchase the WeMos D1, D1 R2, D1 mini and various shields from our AliExpress store . QA2qv.
