Upload the Blink sketch, set to use the Wemo's tiny blue led. Test that it works on USB power. Then test it on the PSU. If all is good, change the Blink sketch to use the external led, test on USB, then the external PSU. Then change the Blink sketch to activate one relay.

WeMosD1 Mini ESP32 is an extremely powerful Wifi + Bluetooth + BLE module with the ESP32 WROOM 32 bit Dual Core microcontroller. It is compatible with Arduino IDE, coming with 4MB Flash Memory, and max. 240MHz clock speed. ESP8266 based development boards are the perfect core for your Internet Of Things project or tiny web server.

WLED Wemos shield. DIY board, 100% compatible with WLED project and WLED sound reactive fork. Integrated level shifter, 4 outputs for LEDs strips, 1 fused out for LED strip, resettable fuse for the development board, exposed I2C interface for display or sensors, relay for energy-saving and 1-wire temperature sensor.

The Ground and the VCC pins of the module needs to be connected to the Ground and the 5 volts pins on the Wemos Mini respectively and the trig and echo pins to any Digital I/O pin on the Wemos Mini, in our example we use D6 for Trig and D7 for Echo. Here is a breadboard layout showing how to connect a wemos mini and HC-SR04. wemos and HC-SR04 Code

Features ¶. 2.13” diagonal ePaper/eInk display. 250x122 pixels. Driver IC: IL3897. Compatible with D1 mini, D1 mini Pro, D32 Pro.

Thanks so much for this Great Tutorial. I had one of these laying around for a couple years. My current project is a Talking clock on Arduino uno and the timer to simulate a push button on esp8266 D1 mini. all the mini does is simulate press 2 buttons. this board now may can know do both , elimiating a lot of wires.
The WeMos D1 R2 is low-cost IEEE 802.11 b/g/n Wi-Fi capable microprocessor development board built around the ESP8266 Wi-Fi module. The ESP8266 is a low-cost Wi-Fi microchip,
