MAX3485 and esp8266 connection schema. The connection is quite simple, you must connect Pin D0 to DE and -RE so you can activate transmission and reception of the data, in the schema, I use D3 and D2 pins, respectively, as RX and TX of SoftwareSerial and you must connecto to RO DI pins of MAX3485, then you must attach 3.3v and GND to the IC pins.

ESP8266 WeMos D1 Mini Amazon: AliExpress: VS1838B Infrared Sensor in Sensor Kit Amazon- One example could be that you want to turn on a red LED when you press volume up and you turn on a green LED when you press volume down on you remote control. Feel free to think about different use cases, try to program the corresponding sketch and share
Step 2: Add the SD Function. As you can see the Nailbuster's circuit determines the main part of the pin connection. We have only one thing to do, to connect the SD pins to the MCU. Each part of the TFT communicates with the MCU through SPI bus. So we have to connect three SD pins to the common SPI pins. SD_SCK to the SCK pin of the MCU.For example, this could be the Lolin D1 Mini, the AZ-Delivery D1 Mini (NodeMCU) shown above, but of course also the Wemos D1 Mini. The "first name" is only a brand or manufacturer name and in my experience does not matter. In the further course of the article I prefer to use the name Wemos D1 Mini, as this is the original. The Wemos D1

If we compare the current consumption of the ESP8266 NodeMCU to the WeMos D1 Mini, we see that the WeMos consumes less energy in modem-sleep mode with on average 27.10 to 35.61 for the NodeMCU. Therefore if we want to maximize the lifetime of a battery powered experiment, we see a positive influence using the modem sleep mode.
WEMOS D1 MINI ESP32 . Contents. WEMOS D1 MINI ESP32. Hardware. Configuration. Uploading. Debugging. Frameworks. Hardware . Platform Espressif 32: ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and Bluetooth.ESP32 integrates an antenna switch, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules.In this example we connect a PIR module to a Wemos Mini. A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. This is from Wikipedia and sums up the operation of a PIR nicely. An individual PIR sensor detects changes in the amount of infrared radiation
Summary of Contents for Wemos D1 Mini V3. Page 1 I don't provide detailed support for the firmware itself as it is not my own. Please READ the documentation on the repository very carefully. When you power up the Wemos, it will start in Access Point (AP) mode. Connect via WiFi to the SSID EMS-ESP and telnet to 192.168.4.1. (f.i..
