Usage
MaESP ESP8266 OLED Projects in Thonny
Project_1: Ultrasonic Ranging
Note: MaESP ESP8266 OLED can be developed using micropython, provided the corresponding firmware is required. You can download the micropython firmware for esp32 from the official website and burn it.
Sensor Connection
We use the HC-SR04 Module at:
https://www.makerfabs.com/hc-sr04-ultrasonic-range-measurement-module.html
Connect the simple sensor to ESP32 boards as follows:
| HC-SR04 Pins | MaESP ESP32 Pins |
|---|---|
| VCC | 5V |
| Trig | IO13 |
| Echo | IO12 |
| GND | GND |
Connect MaESP ESP8266 OLED to your computer through a USB cable.

MaESP ESP8266 OLED also can develop in Arduino IDE, based on C/C++. You should add the ESP8266 SDK in Arduino, and use the Corresponding development firmware
How to increase the ESP8266 SDK in Arduino?
- Open the Arduino IDE, go to File> Preferences
- Enter the following into the “Additional Board Manager URLs” field:
http://arduino.esp8266.com/stable/package_esp8266com_index.json
- Click the “OK” button:
Search for ESP8266 and press install button for the “ESP8266 by Espressif Systems“:
Open the Boards Manager. Go to Tools > Board > Boards Manager.
- Search for ESP8266 and press install button for the “ESP8266 by Espressif Systems“
- Select your Board in Tools >> Board menu, can choose the ESP8266 Boards.
Project_2: Web Server Control LED
1.Connect LED
Connect the long LED pin to the end of the 330R resistor, the other end of the resistance is connected to 3.3v, the short pin of the LED lamp is connected to the IO2/IO16 of ESP32. As follows:
2.Connect WiFi
Open the GitHub. Click to download the MaESP ESP32 Arduino control in the example file.
Open the file and modify the 'SSID' and 'PASSWORD' to local WIFI and password:
const char* ssid = "Makerfabs";
const char* password = "20160704";
Select and set the parameter in the Tools menu, as the picture:
- After verifying and unloading the code, the new client build-up, copy the IP address.
- Open the browser and enter the IP address. You can see the page as follows.
- Users can now turn the led on and off by clicking on/off.
Project_3: NTP Demo
NTP(Network time protocol), which is a protocol used to synchronize computer time. It allows a computer to synchronize its servers or clock sources (such as quartz clocks, GPS, etc.). This demo can display the real-time time on the screen.
-
Open the GitHub. Click to download the MaESP ESP32 Arduino OLED in the example file.
-
Open the file and modify the 'SSID' and 'PASSWORD' to local WIF and password:
- Verify and upload the sketch., show the demo as follows.
