In order to do this, the computer systems require some form of sensors. text/html 2018-11-01T18:55:54+00:00 Anonymous (anonymous@undisclosed.example.com) https://sensorwiki.org/tutorials/building_a_usb_sensor_interface?rev=1541098554&do=diff Building a USB Sensor Interface This section deals with the construction of the AVR-HID device, a 6 channel, 10-bit analog-to-digital converter device which communicates with the computer over the USB connection. The design and specifications of the device are given, along with the schematic, parts list, building instructions, usage and modification information. text/html 2018-11-01T18:55:54+00:00 Anonymous (anonymous@undisclosed.example.com) https://sensorwiki.org/tutorials/choosing_an_avr_microcontroller_for_data_acquisition?rev=1541098554&do=diff Choosing an AVR Microcontroller for Data Acquisition Arduino is a wonderful platform for designers, artists and anybody who doesn't want to spend hours picking out chips and learning the AVR toolchain. But for tasks that require high-speed data acquisition, the Arduino has a fatal flaw: no built-in USB means that funneling data to a PC is sub-optimal. The Arduino uses an FTDI chip to do serial to USB conversion, which doesn't allow you you to take full advantage of USB speed. text/html 2018-11-01T18:55:55+00:00 Anonymous (anonymous@undisclosed.example.com) https://sensorwiki.org/tutorials/extending_pwm_output_pins_with_a_texas_instruments_tlc5940_led_driver?rev=1541098555&do=diff Extending PWM output pins with a Texas Instruments TLC5940 LED driver Introduction Microcontrollers like the Arduino were designed to facilitate the use of electronics for designers and DIY enthusiasts. The interface provides a great starting points for a variety of elecronic circuit designs. However, as the microcontroller is standardized, it is also limited in its use. That shows for example in the limited number of PWM (pulse width modulation) enabled output pins. text/html 2022-03-22T19:54:59+00:00 Anonymous (anonymous@undisclosed.example.com) https://sensorwiki.org/tutorials/how_to_increase_reliability_in_your_sensor_interfaces?rev=1647978899&do=diff How to Increase Reliability in Your Sensor Interfaces This page is a log of reliability-related problems we have experienced in building and maintaining custom-made sensor-based interfaces for human-computer interaction. It includes details of problems along the entire chain, from sensors, to computer interfacing, to software processing. Some of these problems may not be easily resolved, but knowing what to expect can be half the solution. text/html 2022-03-22T18:43:20+00:00 Anonymous (anonymous@undisclosed.example.com) https://sensorwiki.org/tutorials/multiplexing_inputs_to_a_microcontroller?rev=1647974600&do=diff Multiplexing inputs to a microcontroller Introduction Microcontrollers commonly offer a finite number of input pins for analog and digital uses. When creating a project that requires more input pins, multiplexing can be used to expand the amount of available inputs using the same number of pins. Multiplexer devices let the microcontroller switch between inputs to read one at a time through a single input pin. This functionality comes at a cost to the sampling rate of the inputs, but is often n… text/html 2022-03-22T18:45:27+00:00 Anonymous (anonymous@undisclosed.example.com) https://sensorwiki.org/tutorials/spatial_position_and_orientation_tracking_with_a_virtual_reality_headset?rev=1647974727&do=diff Spatial Position and Orientation tracking with a Virtual Reality Headset Introduction Real time or recorded 3D movements tracking can be complex to achieve from scratch. Specialized solutions for Motion Capture (MoCap) exist but may be found unadapted to the time frame, budget, or skill set of the project's team. An alternative to this is making use of the capabilities of Virtual Reality (VR) headsets in order to build a less specialized and optimal system that still fits their goals.
