STM32 is a family of microcontroller ICs by STMicroelectronics. The STM32 chips are based on the 32-bit RISC ARM cores from ARM Holdings, such as Cortex-M4F, Cortex-M3, Cortex-M0+, and Cortex-M0 cores.
This switch is very low in cost and can be used in variety of vibration detection projects. It has to legs coming out of it. Normally the two terminal are insulated by a resistance value more than 10MOhm. When someone applies vibratory force on the switch, spring inside the switch vibrates and makes a momentary short circuit between the two terminals
|USBPrayog is a low cost Arduino compatible board, simple single sided circuit board design based on MetaBoard. Can be programmed directly from Arduino IDE. USBaspLoader bootloader emulates this board as standard USBasp programmer, so avr-dude can also program this board. Arduino shield compatible, so that more functionality can be added stacked on top of it. Get started with USBPrayog|
|We will be learning TWI/I2C through an interfacing example. TWI/ I2C is a popular protocol for communication between Integrated Circuits. Huge number of peripheral ICs (Memory, flash, DAC, ADC, Audio controllers) uses I2C for communicating with their respective host controllers or Processor. One such chip is an 12 bit Digital to Analog converter MCP4725 by Microchip.READ MORE|
