An open source ventilator created by a team at MIT as an emergency response to the growing need for ventilators during the COVID-19 pandemic. Please read through all documentation and safety information linked in the properties before using any device in a clinical setting.

A semiconductor diode formed by the junction of a semiconductor with a metal.

An Arduino Uno powers this autonomous “follow me” cooler that connects to a smartphone via Bluetooth and uses GPS to navigate. The robot cooler connects to a smartphone via Bluetooth and uses GPS to navigate. All the electronics will be contained in the base so that other objects can be carried as well. The electronics were installed in the box cutout under the platform. An Arduino Uno and a 5v battery to power the sensors, Bluetooth, and control logic. A 3s LiPo battery was used to power the motors. A HC-05 Bluetooth module was mounted at the front of the platform for better range. The rest of the components including a L298N motor driver, PAM-7Q GPS, and HMC6883L compass were mounted inside and connected to the Arduino through the breadboard. The compass works with I2C, so we connected the SLC and SDA pins to A5 and A4 respectively. The rest of the pins were connected through digital I/O.

White-on-blue 20×4 LCD can be used to add an eye-catching display to your electronics project. An LED backlight enables viewing in dim lighting conditions. This unit uses the HD44780 interface found on most parallel character displays.

Double pole, double throw switch in default open position.

A system that converts an analog signal into a digital signal.

An electroacoustic transducer; a device which converts an electrical audio signal into a corresponding sound.

A feed through insulator that provides a desired value of capacitance between the feed through conductor and the metal chassis or panel through which the conductor is passing.

TO127P2020X500X2100-15 IPC-7351B 5.0mm STMicroelectronics

This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. This chip is like a rotary switch - it internally routes the common pin (COM in the schematic, SIG on the board) to one of 16 channel pins (CHANxx).

TO127P2020X500X2100-15 IPC-7351B 5.0mm STMicroelectronics

The mini 8×8 Dot Matrix LED Display Module MAX7219 is based on the compact MAX7219 chip, it is a serial input common-cathode driver that interfaces micro-controllers to LED matrices.
