This is an arduino nano based soldering station. **Tested, working version.**
-Designed to work with rotary encoders.
-Built in Beeper.
-Built in memory buttons to store often used temperature values.
-Built in Debounceing for the buttons. (up to 7 buttons, built in 3 buttons)
-Designed to work with a MAX6675 module for temperature readings from a K-type thermocouple.
-Built in LCD head...
This a PCA9665 I2C controller board for the MSKZIO-bus.
In the schematic I use a DS1678+ RTC device, but actually I would encourage to use the DS1307 RTC device - its compatible and the clock is working, even when power is turned off
ESP32-WROOM-32 is a powerful, generic Wi-Fi+BT+BLE MCU module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding.
At the core of this module is the ESP32-D0WDQ6 chip*. The chip embedded is designed to be scalable and adaptive. There are two CPU cores that can be individu...
This projects is a device controlled thru i2C, it has a set of instructions to control two leds, two buzzers and a combination of them.
The device uses an ATTiny85 and it connects to an RaspberryPi to send the commands.
The instruction for the device are:
- 0x00 --> Does nothing
- 0x01 --> All Buzzers ON, All LEDs OFF
- 0x10 --> Al Buzzers OFF, All LEDs ON
- 0x11 --> All Buzzers ON, All LEDs O...
=I2C GPIO extender=
Test implementation (SHOULD be enhanced/optimized) for 12 non-isolated and 4 isolated hardware de-bounced inputs for my OrangePi-Zero 'pseudo PLC'.
Can be used as dedicated I2C extender with single hardware IRQ line with possible any I2C capable controller. Included level shifting circuit make it compatible with 3.3V MCUs.
