Sending data over LoRa with Heltec ESP32 WifiKit. Having two ESp32 boards, the first test that come in mind is to send some packets!
Programming in Arduino IDE an HELTEC ESP32 lora wifi kit (v2) is the same as any other ESP board. Install Arduino IDE and then set the board in “Boards Manager”. In the “Preferences” window of the ArduinoIDE enter https://dl.espressif.com/dl/package_esp32_index.json into Additional
Temperature and humidity reading from RHT03 (also known as DHT22) using ESP8266 WeMos D1 mini board. As many other examples available on the internet, it was inevitably to post myself a temperature and humidity reading application. The values from sensors are
The version 1.1 of Wemos D1 mini PRO board has CP2104 as USB to UART bridge. To get started with this board and/or first stepts for using Arduino IDE, follow the link on wemos or search on google on that, plenty
Programming an Atmel AVR (AtTiny45 or AtTiny85 ) microcontroller can be achieved using a custom programmer or you can use an existing one. In my case, I have a Sparkfun Tiny AVR Programmer
ESP8266 Wemos D1 mini PRO board has an external antenna connector, besides the internal antena. The external antenna is not enabled. To do this, you must move the zero value resistor R16. Notice the position were it should be the
D1 mini Pro is a wifi board with 16MB flash, external antenna connector and built-in ceramic antenna based on ESP-8266EX Features: 11 digital input/output pins Interrupt/pwm/I2C/one-wire 1 analog input(3.2V max input) 16M bytes(128M bit) Flash External antenna connector Built-in ceramic
In this article we will discover the temperature OneWire DS18B20 temperature sensor, available also in a waterproof version. The DS18B20 is a so called 1-wire digital temperature sensor. “1-wire” make this sensor really cool and you can connect multiple devices together, utilizing only
When you connect the WeMOS D1 mini board for the first time on your Windows computer through a USB cable, it might be the case to install a USB-to-SERIAL driver. The board has a USB-to-SERIAL converter (CH340 chip). The driver is
