Hi, I am trying to connect pyfirmata with Arduino for getting the HC-SR04 sensor data.
PS: StandardFirmata is uploaded to the board already
from pyfirmata import * import time port ='COM5' baud = 57600 board = ArduinoMega(port, baudrate= baud) trigpin = board.get_pin('d:2:o') echopin = board.get_pin('d:3:i') start=0 end=0 trigpin.write(0) time.sleep(5) while True: trigpin.write(1) time.sleep(3) trigpin.write(0) while echopin.read(0): pass start = time.time() while echopin.read(1): pass end = time.time() print((end-start)/58.0*1000000) time.sleep(1)
But it seems its not working at all. Says:
Traceback (most recent call last): File "D:\Codes\Research\pyth\us.py", line 26, in <module> while echopin.read(0): TypeError: read() takes 1 positional argument but 2 were given
