# Simple incubator
The goal is to create a simple controller of temperature for an incubator.
## Pinout
| Pin Port | Function | Incubator Functions | Description |
| -------- | -------- | ------------------------- | -------------------------------------------------------------------------------------------------------- |
| PC6 | /RESET | /RESET | - Low level Reset pin.
- DTS pin for Serial communication.
- SS pin for SPI communication. |
| PD0 | 0 | RX | RX pin for Serial communication. |
| PD1 | 1 | TX | TX pin for Serial communication. |
| PD5 | 5 | OUT_FAN | Pin for fan control. |
| PD6 | 6 | PID_CONTROL | Pin for PID control (need to have PWM). |
| PB2 | 10 | OUT_ERROR | Pin for Error notification. |
| PB3 | MOSI | MOSI | MOSI pin for SPI communication. |
| PB4 | MISO | MISO | MISO pin for SPI communication. |
| PB5 | 13 | SCK
MONITORING_LED | - SCK pin for SPI communication.
- Pin for Monitoring LED. |
| PC0 | A0 | TEMP_EXT3 | Pin for One-wire external temperature sensor 3. |
| PC1 | A1 | TEMP_EXT2 | Pin for One-wire external temperature sensor 2. |
| PC2 | A2 | TEMP_EXT1 | Pin for One-wire external temperature sensor 1. |
| PC3 | A3 | TEMP_PCB | Pin for One-wire temperature sensor in the PCB. |
| PC4 | SDA | SDA | SDA pin for I2C communication (Slave I2C). |
| PC5 | SCL | SCL | SCL pin for I2C communication (Slave I2C). |
## Power supply
- Plug for 12/18/24 V.
- LM7805 (DDPAK/TO-263 for 5 V @ 1.5 A) µC power supply.
## Schematic
- Minimal connections for ATMEGA328:
- Serial communication and programming with FTDI board:
- ISP communication for burn boatloader (and programming if you want it):
- Step-down converter to 5 V:
## Inspiration for PCB
- Resistor + Capacitor: 0805

- ICSP - TAG connect - take care of pin mapping !
- FTDI232.
## Get inspired from scale board
