Temperature measuring and controlling module for microcontroller experiment. Temperature control is a process in which change of temperature of a space (and objects collectively there within), or of a substance, is measured or otherwise detected, and the passage of heat energy into or out of the space or substance is adjusted to achieve a desired temperature.
The Freescale 68HC12 microcontroller family is an enhanced 16-bit version of the 68HC11. The Handy Board robotics controller by Fred Martin is based on the 68HC11. [6] A MC68HC24 port replacement unit is available for the 68HC11D, which lacks ports B and C. When placed on the external address bus, it replicates the original functions of B and C.
An Embedded Controller (EC) is a microcontroller in computers that handles various system tasks. Now it is usually merged with Super I/O , especially on mobile platforms (such as laptop). Tasks
7-23-channel 130 kS/s 12-bit differential Analog-to-Digital Converter (ADC), no amplifiers; 1 analog comparator; Two USARTs, one SPI, one dual-mode TWI; Multi-Voltage Input/Output (MVIO) support on 3 or 4 pins on Port C; 4 Configurable Custom Logic (CCL) cells, 6 Event System channels; AVR EA-series. 8–64k flash; 28–48-pin package; internal ...
The 68HC05 (also abbreviated as HC05) is a broad family of 8-bit microcontrollers from Motorola Semiconductor (later Freescale then NXP). Like all Motorola processors that share lineage from the 6800 , they use the von Neumann architecture as well as memory-mapped I/O.
The Low Voltage Series include the MSP430C09x and MSP430L092 parts, capable of running at 0.9 V. These 2 series of low voltage 16-bit microcontrollers have configurations with two 16-bit timers, an 8-bit analog-to-digital (A/D) converter, an 8-bit digital-to-analog (D/A) converter, and up to 11 I/O pins.
The advantage of the low voltage control system is the ability to operate multiple electromechanical switching devices such as relays, contactors, and sequencers using inherently safe voltage and current levels. [15] Built into the thermostat is a provision for enhanced temperature control using anticipation.
Hence, the regulated temperature is like a sliding mode of the variable structure system setup by the bang–bang controller. Symbol for a bang–bang control. In control theory, a bang–bang controller (hysteresis, 2 step or on–off controller), is a feedback controller that switches abruptly between two states.
