Raspberry Pi

Today we came to school with the following tasks:

1. Establish serial communication with RPi and Arduino
2. Use 2 ultrasonic sensors
3. Test conductive paint

I came to school and started up my Raspberry Pi, which I setup over the weekend, and started browsing for examples online.

This was the simplest and cleanest example I found. I reused the arduino ping sensor code and rewrote the python code to the following:

import serial

ser = serial.Serial ('/dev/ttyACM0', 9600)

while 1:

if(ser.in_waiting >0):

line = ser.readline()

print(line)

Result:

Next I decided to research the conductive paint a bit more:….
