I am using arduino to sample sensor and it sends out the value to the digital pin. I want to read this digital value using nrf51dk. Is there any example using digital read? I will be using uart service to send the data.
What is the range of this digital value you are outputting?
There are three sensors with numeric output value between 0-100.
In the SDK you can find examples for alot of different communication protocols. This includes UART,SPI and TWI/I2C.
