Airsoft-HUD
Transparent HUD for an Airsoft gun that shows how many BBs are left in your magazine and keeps track of your number of kills and deaths during a match. A XIAO ESP32-C3 is used together with a SSD1309 transparent OLED display. An IR Transmitter LED and IR Receiver sensor is used to detect BBs. Video: https://youtu.be/BZJjDX5xyRM
Language:C++7 2 10
AudioRecording_ESP32-C3
An example of recording audio onto a MicroSD card, using an INMP441 microphone and a XIAO ESP32-C3
Language:C++1 1 01
ContinousAnalogRead_ESP32-C3
A simple Arduino project to show how to continously read analog values directly from the ADC (analog to digital converter) on an ESP32-C3. This is much much much faster than calling analogRead(), so it's useful if you need to read values at a high frequency.
Language:C++1 1 11
ESP32-CAM_With_SSD1306
A simple Arduino project to show how to use a SSD1306 OLED display with ESP32-CAM. The reason why this is interesting is that the SSD1306 uses I2C, not SPI. Since the ESP32-CAM doesn't have I2C pins, we have to use the Wire lib to define our own I2C pins.
Language:C++6 1 03
FindEachOtherCompass_ESP32-C3
An Arduino project to create a compass that not only points North, but also points to another person. This is very useful for outdoor teams sports like Airsoft.
Language:C++9 1 22
GPS_Tracking_Cat_Collar_XIAO_ESP32-C3
An Arduino project to log GPS data to a MicroSD using the tiny XIAO ESP32-C3. The components are small and light enough to fit around a cat collar! Now we know where the cat runs around at night :-)
Language:C++11 1 12
SimpleBLE_ESP32-C3
A simple Arduino project to show how to setup a BLE Peripheral device and a BLE Central device, and how to send values from the Peripheral to the Central using Notify
Language:C++2 1 00
