Working with Flame Sensor - Fire Alarm System

One of the components in our starter's kit is a photodiode which detects light. When fire burns it emits a small amount of Infra-red light, this light will be received by the Photodiode (IR receiver). The photodiode in most starter's kit is a YG1006 sensor which is a high speed and high sensitive NPN silicon

Working With Servo Motor

Servo motors are a special type of motor that don’t spin around in a circle, but move to a specific position and stay there until you tell them to move again. Servos usually only rotate 180 degrees (one half of a circle). Servo motors are a special type of motor that don’t spin around in a circle, but

Controlling an LED with a Potentiometer

We previously looked at Analog Inputs (here) where we used a photoresistor and LED to make an ambient light sensor. Today, we will still discuss Analog Inputs but we will be using a different component so we see how analog inputs work from another point of view. We will be controlling the

Introduction to Analog Input- AMBIENT LIGHT SENSOR

We previous discussed Digital Inputs (here) and While switches and buttons are great, there’s a lot more to the physical world than on and off. Even though the Arduino is a digital tool, it’s possible for it to get information from analog sensors to measure things like temperature or light. To do this,

Our 1970's Spaceship Interface

We introduced ourselves to Digital Inputs (here) and we tried our hands with an interactive project that takes action with the push of a button. Now we will be extending that design to something a bit more. We will go design a system using digital input to mimic a 1970s spaceship interface. You’ll make a cool control panel with a switch and lights that turn on

Introduction to Digital Input

Today, we will be introduced to digital inputs and we will be working with push button switches and LEDs to create interactive programs which we will define and control ourselves. Push button switches are really simple components. When you press a button or flip a lever, they connect two contacts together so that electricity can flow through them.

Traffic Light Program and Working with RGB LED

We went over our first program- Blink (here) where we designed a circuit and we programmed it to act as we wanted. We looked at both hardware and software aspects of the program in depth and we tried to explain what each line of code meant. I also urged you
