For an Arduino, When using multiple LEDs and pins, why can’t you wire all the pins to the positive bus?
Homework Answers
This is because attaching too much pins to the positive buses will result in substantial potential (voltage) drop (from a single source) across the circuit. This in-turn will result in substantial current drop. For example, a single LED draws around 2.2 V from the source and if we connect two such batteries to a 3V battery, it will overwhelm the capacity and won't work.

Write an Arduino code to read the current temperature using the LM35 temperature sensor. The code should include the following if the temperature is more than 45 "C: • Turn ON red LED, and after 1 second turn ON the yellow LED, and after another 2 seconds tum On the Green LED. One second later the three LEDS should start blinking (all LEDs OFF for 0.5 seconds, then all LEDS ON for 1 minute), and turn OFF all LEDs after...

You are to create a new application that will execute on your Arduino platform based upon the Blink example that is available in the Arduino Examples folder that you downloaded as part of the IDE. Your application will use a toggle switch to interface with the user. The application will operate by controlling the LEDs based upon the position of the toggle switch. If the user moves the LEDs until new user input is provided. When the user moves the...

I am doing an Arduino Uno project where I made a "Simon says" memory game with 3 neopixel LED strips and 3 - ultrasonics. I have them working independently but I need to combine the code so they work together. Here is what I have: Memory Game #define PLAYER_WAIT_TIME 2000 // The time allowed between button presses - 2s byte sequence[100]; // Storage for the light sequence byte curLen = 0; // Current length of the sequence byte inputCount =...

This question is about the Arduino code.
Please complete a 4-input circuit on your Arduino. Your circuit,
in addition to cycling through a binary representation of the
numbers 0-15 using LEDs, should use the Serial port to output the
decimal equivalent of each of the numbers in the format:
Output: 15
... if the value was 1111, and so forth.
You will be asked to upload your code as well as a photo of your
working breadboard circuit.

By using Arduino Uno
Project Description: PID is used widely in many applications such as temperature control systems, automotive industries, and robotics. In this project, you will implement multiple PID controllers on a zumo robot. The robot must move in a straight line without drifting and it must adjust its speed when it is approaching an obstacle or when an obstacle suddenly gets in its way. To achieve the above part, you will use two PID controllers; one for the...
