Visualise measured data over local network following server/client relationship between Arduino and Raspberry Pi
Hello! Today i’ll show you how to measure DC voltage using Arduino and display the measured data on request from client over same network using some Python code and Raspberry Pi.
Voltage measurement is the simplest task that we can perform using Arduino. Arduino’s internal ADC reference voltage is 5V (Vref=5V) so maximum voltage that we can measure without using external circuit is 5V. It is having 10-bit resolution, 210=1024 values for 0 to 5V scale. 0V corresponds to 0 ADC reading and 5V corresponds to 1023. Single ADC value represents 4.88mV. So the maximum voltage that we measure here is 5V.
