Using an MMA7455 accelerometer with an ESP32 board

The MMA7455L is a Digital Output (I2C/SPI), low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a low pass filter, temperature compensation, self-test, configurable to detect 0g through interrupt pins (INT1 or INT2), and pulse detect for quick motion detection. 0g offset and sensitivity are factory set and require no external devices. The 0g offset can be customer ca ...

MAKING MUSIC FROM CARDBOARD

Fans of MaKey MaKey may find this project similar, but there’s a lot more to the Mini Automat than making music from fruit. The idea for the Mini Automat (which is an off-shoot of the original Automat project by [Dada Machines]) is to make music accessible to anyone. The device functions as a plug and play MIDI-controller that connects to a computer, MIDI workstation (keyboards and sequencers), or ...

Arduino LED Exploration

Arduino LED ExplorationMy program shows you all of the data on your Led from the first light to the normal operation light. From that data you can pick an RS that is good light, but lower in current. You must build the circuit to run my program. You must open a terminal window when you run my program. Bright led can waste a lot of current. Using a higher RS like 470 to 1k you can save almost half of the cur ...
