Gerbil: The Open Upgrade for Your K40 Laser -

After experimenting with a stock Arduino UNO R3, I decided that I needed a better Arduino with at least one additional 16 bits PWM channel without an added price tag. Since I am controlling a CO2 laser, speed or additional processing power are not a requirement since the CO2 gas needs time to ionize and quality engraving takes time.

Smart Grow Room |

My end goal is to have a system that can be plugged in and pretty much forgotten about. The system will be able to notify the user via email/sms if there is any problems. The user will be able to have remote access via web browser/ smartphone and view realtime information and change settings. At the moment the current version is able to control a light via a timer which can be set via dials on ...

Programming the ESP32 with Arduino Code • Wolles ...

Jul 23, 2021· In contrast to the Arduino (UNO), the ESP32 has two I2C interfaces. The standard interface is assigned to GPIO21 and GPIO22. If you use the default, the operation is the same as with the Arduino. This means that you include the library and use its functions as usual. But you have to keep in mind that the ESP32 voltage is volts.
