The Sharp GP2Y0A21YK is a low cost ($13.95) infrared proximity sensor with an analog output that varies from 3.1V at 10cm to 0.4V at 80cm. It has a JST (Japanese Solderless Terminal) connector and needs either a pigtail jumper wire or … Continue reading →

You walk into a haunted hotel, you make a left down the hallway and then out of nowhere, a skeleton comes flying down and makes an attempt to scare you. Now how does that work? It works with the power … Continue reading →

Overview:  To equip a Pententiometer sensor to an Arduino board and test the output on the computer to see if its working. Then attach an LED light to the Arduino board and then adjust the brightness of the LED with the Potentiometer … Continue reading →

The sensor that I chose is an altitude sensor. This particular sensor measures altitude. The altitude sensor can help in the project that I am doing because it can measure the altitude of the quadrotor helicopter. The sensor outputs are digitized … Continue reading →

Journal 3 – Color Sensor “The sensor essentially consists of an RGB LED and a photo cell placed right next to each other with a small divider between them so that the light of the LED does not directly hit … Continue reading →

Objective: Build an interactive sensor using a POT Materials: Arduino, LED, POT Methods: Connect the POT to the Arduino (+5 outside, Gnd outside, Remote middle) Connect the LED. Open the monitor to view the values. Adjust the pot to change … Continue reading →

Objective:  To add a sensor (potentiometer) to our basic Arduino setup, troubleshoot, and make a few basic changes. Materials: Arduino Milanove (controller), Potentiometer (sensor), cable connector, LED (actuator) Procedure: 1.  Plug the arduino into the computer by using the USB … Continue reading →
