Product Review : Servo Motor SG90

                    In our previous post, we have seen the simulation on how we can control the servo motor. Today we have a chance to test the actual servo motor. The servo motor that we will use is Tower Pro SG90. Basically, the SG90 servo motor is a low-cost plastic gear RC servo with torque (kg-cm) of 2.5. 

Arduino Tutorial #10 : MakerUno - Making Tone

Arduino Tutorial #10:

MakerUno - Making Tone

     

          In our previous post, we have a look into controlling the onboard led. Today, we shall look into how we can make tone using the onboard piezo buzzer. For simple theory, the positive pin of the piezo buzzer is connected to Pin 8 and the ground pin is connected to the Ground. The image below illustrates the connection.

Arduino Tutorial #8 : MakerUno - Simple LED

Arduino Tutorial #8:

MakerUno - Simple LED 

     

          In our earlier post, we have a look into the MakerUno. Today we shall look into programming the board. Basically, the concept is similar to Arduino Uno, the thing which is different is their built-in led, buzzer and push button. In our post today, we shall look into controlling the built-in led on the MakerUno board.
           The onboard LEDs are connected to the digital pin starting from Pin 2 to Pin 13. To turn on these LEDs, it can be simply done by giving output high to each of the pins. For the first part, we shall make a simple led blinking program, followed by more complicated controlling methods.

UnoArduSim - SERVO Motor 

     

          Previously we have look at using UnoArduSim to control an LED. Today we will look at how we can control the servo motor by using the UnoArduSim simulation tool. But before that, let's look at the theory of servo motor. 

Unboxing The CNC3020T

CNC3020T 

                  This time we will look into a milling machine. To be specific the model which we are looking at is the CNC3020T. This machine is manufactured in China and cost around $500 USD. The machine is capable of doing engraving. This machine is useful for industrial, research, education and hobbyist purpose.

Digispark#2 : Interfacing Digispark With Temperature Sensor LM35

Digispark #2:

 Interfacing Digispark With Temperature Sensor LM35

                 In our previous post, we look on how to interface the Digispark with LCD 16x2. Today we will look at how we can interface the temperature sensor LM35 with Digispark. For this, we will need to have the LM35  temperature sensor, Digispark and the LCD. Before going further let's look at LM35.

 Interfacing Digispark With LCD 16x2

                 In the previous post, we have seen the introduction to Digispark and make a simple led blink project. This time we will use the Digispark to interface with 16x2 LCD display. Since the number of a pin on Digispark is limited, we will use the i2C protocol to connect with the LCD. The item we will use is as shown below.
