    Arduino PID for propeller pendulum to balance horizontally

    Dear all, this hobby project I setup is using an encoder to make the stick to be 90 degress which is at 1500 steps (0 degrees=perfectly horizontal using PID control). My encoder counter code is obtained from video here and I have tested it which works perfectly well. Since this encoder is 1200...

    How to get data from a circuit board with a microcontroller?

    Hi, I'm a complete novice in field of electrical circuits and have zero knowledge in this domain. Yet, I wanted to work on IOT but instead of using raspberry pi and similar, I wanted some data out of few devices. For example, I have a very old traditional treadmill which reflects the speed at...

    When and why does embedded Electronic Control Unit(ECU) use default calibration values?

    Typical embedded ECU stores real calibration values and default calibration values in Non-Volatile Memory(NVM). Let's say ECU is Steering Controller and it's primary function is Lane Keep Assist(LKA). It is mounted in a commercial truck. It programs camera's real and default calibration values...

    Controlling AC powered devices

    Hi All, As an electronics engineer, I have always worked with low voltage circuits and found it very difficult to control high voltage, AC powered devices. In my last project, I needed a power board that I can just plug my MCU or DSP and control an instrument that needs high power. I wanted an...

    Adding Voltages

    I am working on detecting fingers being placed on guitar frets. My idea is to run a small voltage through each of the strings, a different voltage for each string. The player touches the string and makes the string touch the fret. On the end of the fret I detect the voltage with a...
