CAN bus data read with MCP2515 on CANhacker terminal via Arduino IDE and ESP8266 Car or battery BMS  Code link- https://github.com/gsrathore97/CANHackerProject Video link- https://www.youtube.com/watch?v=rWEZJeNOWSg There is two configuration 1- BMS and Microcontroller are already communicating with each other in the manufacturer's system In this case we can only read from this system using Arduino(broadcast type). 2- BMS is there with CAN system In this case we have to send CAN request frame commands to get the data on Arduino only.(Command and listen)

Neo-6m GPS module testing code- "No GPS data received: check wiring" error problem. solutions 1. Do not short circuit Antenna to pins 2. Test in open Sky 3. Battery may low, power it to recharge. 4. 5V power is best 5. Patience while connecting wait 2 min 5min atleast. 6.

Understanding the Electromagnetic Spectrum and Data Communication Frequency Bands In today’s connected world, data communication technologies rely on different frequency bands within the electromagnetic spectrum to transmit signals efficiently. Whether it’s Wi-Fi, mobile networks, satellite communications, or radio broadcasting, each technology operates within a specific frequency range to optimize performance and avoid interference. What is the Electromagnetic Spectrum? The electromagnetic spectrum refers to the range of all possible electromagnetic waves, from low-frequency radio waves to high-frequency gamma rays. The spectrum is divided into different regions based on frequency (measured in Hertz, Hz) and wavelength (measured in meters). Main Regions of the Electromagnetic Spectrum Radio Waves (3 Hz – 300 GHz) Used for communication technologies like AM/FM radio, television, and wireless networks. Microwaves (300 MHz – 300 GHz) Used in radar, satellite communications, GPS, and Wi-F...
