Communicating with a Raspberry Pi from an Arduino Using Node-RED @Raspberry_Pi #PiDay #RaspberryPi

via KTINKERER I wanted to add some sensors to a Raspberry Pi but I was quickly running out of GPIO pins, luckily I had some spare Arduinos so decided to experiment with plugged one into the Pi. I got the Arduino set up with the sensors and connected it via USB to the Raspberry Pi. To get the readings in Node-RED install Node-RED serialport, restart Node-RED and select the serial...

Raspberry Pi is a wireless audio streaming music server 

A tube audio amplifier has been developed by Pi 2 Design with a Raspberry Pi version that has a standard 40-Pin GPIO/I2S interface and TI PCM5102A 24-Bit, 192kHz DAC. Developed under the Ceres name, the Dual-Triode tube amplifies the incoming signal which is then routed to the Class-A solid state buffer to provide the proper … This story continues at Raspberry Pi is a wireless audio streaming music server  Or...
