A telemetry system for a Greenpower racing go-kart (https://www.greenpower.co.uk/), built using LoRA and programmed with C++. This project has kindly been funded through the hack club winter of making grant program.
- Temperature of the motor
- Speed of the vehicle
- Temperature of the batteries
TODO:
- Current sensor

- Web app?
- SD Datalogging
- Bigger screens
- Graphing of results?
- Elapsed time of race
- Tyre pressure
- Strain sensor
- Better casing designs
- Gyroscope?
- Swith to imu?
- Battery voltage
- Test the range of the system
- Throttle position
- Battery Voltage
- Recording amp hours used
- Distance travelled
- Lap number

- 1 LED BLINK: Oled initalization has failed, check if OLED pins are correct (By default they are) and if the OLED is visibly damaged.
- 2 LED BLINKS: No packet was recieved by the reciever, check antennas on both reciever and transmitter.
- 3 LED BLINKS: Motor temperature is 85 C, this is normally an indicator that the DS18B20 sensors are broken or not working (Or your vehicle is running too hot).
- 4 LED BLINKS: Heatsink temperature is 85 C, this is normally an indicator that the DS18B20 sensors are broken or not working (Or your vehicle is running too hot).
