It recives current temperature from thermometer and using PWM, regulates duration of time, when the heater is turned ON in order to keep steady, set temperature. There are two supported control modes: proportional and two-positional.
- LPC1768, ARM Cortex M3 with KEY1 and KEY2 buttons
- dedicated LCD screen with ILI9325 driver
- Pmod TMP2 16-bit, temperature sensor, that uses I2C protocol, together with custom pull-up
- heater, build with resistors, connected to transistor
- UART to output debug logs
