DESK OF LADYADA - STEMMA Sunday - I2C Fan Controller + Makin' Beeps
78This Sunday, like many, is a STEMMA sunday! This weekend we finally got around to testing an older design from a few months ago for the EMC2101 I2C fan controller. It has PWM fan, temperature reading, and a tachometer - its designed for controlling fans but we think the tachometer could be useful for some other purposes as well. We also made some songs on the MagTag using the built in buzzer and learned that the ESP32S2 cannot DMA to the DAC - so it's beeps for us!
The Great Search - Piezo and Magnetic Buzzers
Listen to this - your next project or product needs to make some beeps and boops? Its a great time to integrate a piezo or magnetic buzzer. We'll chat about the differences and which one could work for your design. We'll also show you how to find the same buzzers we use on boards like the MagTag / CircuitPlayground and CLUE.
