+The WeMos D1 and clones is a single board computer based on the ESP8266 which combines a 32-bit RISC processor with a WiFi transceiver.  The WeMos and clones are available on eBay, amazon, and [https://www.aliexpress.com/item/USB-CP2102-32M-FLASH-WeMos-D1-ESP8266-Internet-Wifi-Module-for-Nodemcu-Lua-V3-DC-Power/32814901470.html AliExpress for $3.19].  
+
+It can be programmed using Arduino after installing support for the ESP8266 platform:
+  1. Install board manager URL (http://arduino.esp8266.com/stable/package_esp8266com_index.json) in File->Preferences->Additional Board Manager URLs.
+  2. Install board manager Tools->Board->Boards Manager->esp8266 (at bottom of list)
+
+Test by entering a basic sketch:
+
+{{{
+#define LED_BUILTIN 2
+
+// the setup function runs once when you press reset or power the board
+void setup() {
+  // initialize digital pin LED_BUILTIN as an output.
+  pinMode(LED_BUILTIN, OUTPUT);
+  // initialize serial communications interface
+  Serial.begin(115200);
+}
+
+// the loop function runs over and over again forever
+void loop() {
+  static uint32_t count;
+  Serial.println(count++);
+  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
+  delay(1000);                       // wait for a second
+  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
+  delay(1000);                       // wait for a second
+}
+}}}
+
+* Configure the interface to your board:
+  1. Tools->Board->Generic ESP8266 Module
+  2. Tools->Flash Mode->DIO
+  3. Tools->Flash Size->4M (1M SPIFFS)
+  4. Tools->Reset Method->nodemcu
+  5. Tools->CPU Frequency->160MHz
+  6. Tools->Upload Speed->921600
+  7. Tools->Port-> <COM Port your board is on...see Windows Device Manager>
+
+* Compile your program (sketch) and upload it to the board by pressing the -> tool 
+  When the download finishes, the blue LED on your board should be blinking and if 
+  you launch the serial monitor (Magnifying glass tool in the far right of the toolbar),
+  you should see your board sending out an increasing count every 2 seconds.
