The following sensors are available for you to use in your projects in addition to the peripherals you have worked with during this quarter. Let us know if you want to use them!
Unfortunately, the Raspberry Pi does not have a digital-to-analog convertor (DAC) peripheral. In order to use these sensors requires that you use an DAC chip such as the MCP3008. We have example code showing how to use that chip.
100 AH3503/UGN3503 Ratiometric Linear Hall Effect sensors (voltage proportional to magnetic field)
10 Sharp GP2D12 IR Distance sensors (voltage proportional to distance)
100 TSAL1600 IR LEDs
10 HC_SR501 Infrared PIR Motion sensors
10 Keyes HC-SR04 Ultrasonic Sensor/Distance Measuring modules (time of flight)
100 A3144 A3144E OH3144E OH180U Hall Effect sensors (schmitt trigger followed by open collector transistor)
HC595 shift registers (SPI-like)
10 MCP3008 Analog-to-Digital convertor
MCP4921 Digital-to-Analog convertor
MCP4162 Digital potentiometer
2 DHT22 Temperature-Humidity Sensors (not pure SPI)
