Tutorial 7: Arduino Melody Circuit for Beginners
Aug 01, 2012The required components are shown in this photo: Circuit Diagram. The circuit diagram shows that the positive terminal of the speaker is connected through a 100 ohm resistor to pin 8 of the Arduino.
Simple DC Motor Speed Control Circuit Diagram using IC 555
May 14, 2015The DC MOTOR SPEED CONTROL circuit is primarily a 555 IC based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage. The method of PWM is explained here. Consider a simple circuit as shown in figure below. If the button is pressed if the figure, then the motor will start rotating and it will be in motion until the button is pressed.

Raspberry Pi Light Sensor: A Simple LDR Tutorial
I want to use an LDR or photo-transistor for a dimmer on my clock project, which uses an Adafruit 1.2″ LED display and a Raspberry Pi Zero. Instead of using the RC circuit with an RC timing routine in the Python code, I’m thinking about using a comparitor circuit instead.
Tutorial 4: Arduino Knight Rider - Starting Electronics
Jul 31, 2012Circuit Diagram. The circuit diagram is shown below. It is simply eight LEDs interfaced to the Arduino pins 2 to 9. Building the Circuit. Place the LEDs next to each other in the breadboard so that the anode (longer lead) is at the left and the cathode is on the right.
Line Following Sensor (DIY) - waihung
Jun 02, 2013This is my attempt to create a simple line following sensor on my own. These sensors can be easily bought but it can be quite expensive considering that the components on it are quite simple.

Automatic Washroom Light Switch Circuit Diagram and Working
Apr 10, 2018Introduction. In this project, I will show you how to design and build a simple Automatic Washroom Light Switch Circuit, which will automatically turn on the when you enter the washroom and turns it off when you leave.
Simple Metal Detector Circuit Diagram using 555 Timer IC
May 14, 2015the 555 timer either sourcing or sinking a fixed amount of current from its pin 3, so I see as the output is a fixed squarawave tone so the increasing of L coil will increase voltage on it that increasing current draining from pin 3 hence reducing tone. simple !
