PowerShell Cron Script

On the Pi I am using a NRF24L01+pa+lna SMA Antenna Wireless Transceiver, this provide more range (1000m) from my main unit. All the nodes in the network will be running on Arduino chips and using a Mesh network so the house should have good coverage. First, wiring in the NRF24L01 to the Pi. Continue reading
