    Amplitude modulation with MCU and NE 555

    Hi, I want to build an IR transmitter (~ 38kHz). My plan is to use a NE555 timer to generate the carrier wave (A-stable Operation), modulate it with a micro controller, and transmit modulated signal via IR LED. My question: Can I connect the micro controller output pin directly to the CONT...

    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...

    High quality audio recording with MCU

    Hi everyone. I am something like a musician, but I also like to experiment with electronics a lot. I own a BOSS looper pedal, but it kinda doesn't fit my needs as well as I firstly thought. Recent days I was thinking abou whether is possible to somehow utilize some sort of MCU or just some ARM...
