ARM Microcontroller Based Projects for Engineering Students

The ARM family is the most advanced family of microcontrollers. Nowadays so many applications are developed based on ARM controllers and processors. The ARM stands for Advance Risk Machine. Currently many controllers and processors families are available like 8051, AVR, PIC, Motorola, etc, but still the ARM is very popular and is chosen for many applications and domains. There are many reasons for their in embedded based applications, such as their device functionality, set of peripherals and high speed data processing.
The ARM manufactures each add their own mixture of peripherals and add on functionality to the chip. Many chips with ARM family include a A/D converters, counters/timers, capacitive touch controller, LCD controller, USB, Wi-Fi base band etc; there are already built into the chip. This saves on port cost, design time and physical space on the circuit board. Most of the companies prefer to use ARM families over and over again. The ARM9 and ARM7 are the most popular in ARM families.

Differences between ARM Family and Other Families (like 8051, PIC, AVR):

  • The ARM executes all instruction in only one cycle and other family controllers takes more than one cycle.
  • The ARM has load store architecture i.e. data processing instructions can not access memory directly; data has to be stored in a register before processing. Other families can access memory directly.
  • In ARM families all peripherals are in built in a chip

ARM Based Industrial Automation Using GSM:

This application is very helpful for the industries. For any application in the industries there are many parameters to be handled. This application is used to save the power and major components in the industry based on sensors. The temperature sensor is fixed at a specified location, for our application to be performed. The sensor gets the values and sends the information to the microcontroller continuously. The microcontroller receives the values and sends the corresponding values to LCD display.

Whenever the temperature exceeds the set point the controller drives the fan ON and if the set point decline its drives the fan OFF. Whenever the smoke exceeds the set point the controller drives the BUZZER ON and if the set point declines its drives the BUZZER OFF. Whenever the light exceeds the set point the controller drives the light ON if the set point decreases its drives the light OFF. The GSM modem is connected to the microcontroller through MAX 232. GSM modem first makes a call and then sends the message. This application is for industries with heavy parameters to handle. Now a day these are used in all kinds of industries and commercial complexes.
