The remote control of an RC car was modified by extending wires from the backward, forward, left, and right switches. Grounding any of these wires completes the circuit and sends a signal to the car. The intention is to...
This circuit utilizes a 16x2 LCD to display a count value using an 8051 microcontroller. The maximum count value is set to 99. The circuit consists of the 8051 microcontroller, a 16x2 LCD, and two switches designated for incrementing...
Faulty readings from the DS18B20 temperature sensors used in tank thermometers were likely caused by the waterproofing method involving heat shrink and silicone. This situation provided an opportunity to enhance the code for better tolerance against erroneous readings. The...
The Arduino 2009 functions as an independent weather station without a display. It can operate autonomously for extended periods, sampling data from sensors until the RAM reaches full capacity. The collected data is stored in a designated sector of...
The notes for the fourth and final class are available on the Spooky Arduino class page. At the conclusion of the class, Mark from Machine Project awarded each student a merit badge. A project utilizing techniques from this week's...
A typical device that requires less than 5v and draws less than 25mA is an LED. A LED must be supplied with an exact voltage for it to operate correctly. Because it requires LESS than 5v, a dropper resistor...
