I purchased a PI weather board (found here ) which gives you temperature, humidity, barometer , 4 high power dc outputs, and a couple external 1-wire sensors ports. Connectors for power supply and TEC are provided. Using the L298 commands, the motor will spin respecting DC motor speed control strategy. Fan is a Noctua NF A12 PWM which is connected via a PCA9685 with the Raspberry. bang_bang true # set to true to use bang bang control rather than PID temperature_control. to control temperature, you can use "PID Compact" of STEP7 Basic with PWM output (output_PWM). I was thinking of using a Microchip PIC (PIC16F1823) since I needed alot of I/O and not needing a SPI/I2C since I'm having the LED display on the same PCB. For this I want to use a PID controller.
