Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal processing applications, introduced today the industry’s first MEMS accelerometer with Min/Max offset sensitivity over the full temperature range. The ADXL350 3-axis MEMS accelerometer has maximum offset temperature sensitivity of ±0.31 mg/°C on the X/Y axes and ±0.49 mg/°C on the Z axis, guaranteeing predictable and quantifiable performance across the full temperature range of −40°C to +85°C.
The MAX98355A/MAX98355B are digital pulse-code modulation (PCM) input Class D power amplifiers that provide Class AB audio performance with Class D efficiency. These ICs offer five selectable gain settings (3dB, 6dB, 9dB, 12dB, and 15dB) set by a single gain-select input (GAIN).
This is basic example on how to send and receive one character over AVR UART peripheral. It is easy to understand and if you have not worked with UART on microcontroller before, it is good starting point. In article AVR serial port UART register usage we have explained details of register usage. Here we will give one example in order to see complete project and test this on your microcontroller.
The reed switch is an electrical switch operated by an applied magnetic field. It consists of a pair of contacts on ferrous metal reeds in a hermetically sealed glass envelope. They are often used in alarm systems, on bicycles for wheel speed measurement and in many other devices. Here we will say few words about reed switch and show you very interesting video how they are made
