When I connect this/your circuit but provide 30V from the Relay (instead of 5V from the Pi) it does not want to work. Introduction. The Raspberry Pi is a credit card sized single-board computer developed in the UK by the Raspberry Pi Foundation and based on the Broadcom BCM2835 system on a chip. The board features a universal I/O architecture with digital inputs, a set of relays, analogue I/Os and broad connectivity thanks to 1-Wire bus, I2C and UART ports. In this article, we will explore various hardware and system software configurations configurations available through rPI3 for the users. Make sure the Raspberry Pi detects the Arduino board on the I2C bus. This was installed from the Raspberry Pi's Linux command line using: sudo apt-get install python-smbus. dtb), if you are programming a HAT EEPROM. If you know how fast your I2C-device is, you could chose a slower I2C-clock-frequency, so that the device does not stretch the clock. It can be used in both SPI and I2C.
