While working on a steering mechanism for my robot, I wanted to record the current draw of the motors. The data would give me a rough idea about the friction in the mechanism so as to decide whether I need a different motor controller or different ideas. How can I go about collecting the data?

For my current project, after considering a couple of options, I chose to develop a custom communication protocol to connect two programs: one runs on Arduino and another on a Raspberry Pi (RPi). In this post, I’d like to share my experience of going through the development process.

Have you thought of how to filter the data coming from an analog sensor? In this post, I describe:

After connecting an infrared sensor to my Arduino, I noticed that an ultrasonic sensor, which is connected to the same board, started reporting inconsistent measurements. The investigation took me a few hours, but now I know better to pay attention to the power requirements for electronic components.
