Getting Started with Arduino Due - Connecting LED's and PWM Tutorial

Let's first have a basic introduction of Arduino Due Board. It is an ARM controller based board designed for electronic Engineers and Hobbyists. ARM architecture is very influential in modern electronics. We are using the ARM architecture based controllers everywhere. For example we are using ARM controllers in our mobiles, iPods and computers etc. If someone wants to design industrial systems, it must be on ARM controllers. ARM controllers are very important because of the frequency of their operation and data bus size.

Here is a simple tutorial to blink an LED for every 1000ms.We will connect an LED at PIN13 through a 220Ω current limiting resistor.

Now lets check this experiment to understand the PWM (Pulse Width Modulation) concept in Arduino Due board.

The circuit is connected on breadboard as per the connections shown in above image. However one must pay attention during connecting the LED terminals. Although the buttons can show bouncing effect but in this case it does not cause considerable errors, so we need not worry this time.

DIY Arduino Frequency and Capacitance Meter

Here are the two interesting and useful DIY tutorials to build a frequency counter and a capacitance meter using arduino uno.

1) Capacitance Meter
Although there are various equipments for measuring the capacitance, but all these devices are costly and not for everyone. With that in mind we have designed this simple Arduino Capacitance Meter to measure the capacitance of unknown capacitors.

2) Frequency Counter

Similarly there are various devices to measure the frequency but all these devices are costly and are not for everyone. With that in mind we have designed this simple yet efficient Frequency Counter using Arduino Uno and Schmitt trigger gate.
