Every day, people depend heavily on electronic devices to get things done around the house and at their job places.  This friendly guide has all you need to know everything about a custom circuit board, and where you can get the best custom circuit boards for your needs. Among the key subjects on  Custom Circuit Board include: 1. The Basics You Should Know About Custom Boards: This section briefly ...

In case you don't have an AVR programmer but you do have an arduino, the arduino can be converted into an AVR flash programmer, meaning it can program bare AVR microcontroller chips. Say if you have an AVR chip and you want to program the chip, so that the program that you've written and compiled gets stored into the flash memory of the chip to be executed. The arduino, with some specific wiring, can act as ...

An infrared (IR) distance sensor is a sensor that can measure distance from a solid or physical object. An infrared distance sensor does this through light waves. It sends out infrared light and waits to receive it back at the receiver end. If it receives back the infrared light, this means that the light waves have bounced off of a physical object and has returned back to the sensor. If it does not receive ...

An ultrasonic distance sensor is a sensor that can measure distance from a solid or physical object. An ultrasonic range finder does this through sound waves. It sends out high-frequency sound waves and then waits to listen back for these sound waves. If it has heard back these sound waves, then this means the sound waves have bounced off of a physical object and has come back to the sensor, which means a p ...

In this project, we will go over how to build a servo motor circuit using an arduino. This is a circuit which can control and rotate a servo motor to rotate a certain amount of degrees. Specifically, in our circuit, we will make it so that the servo motor rotates 180 degrees and then stops and then rotates 180 degrees back (in the direction it began). To control the servo, we connect it to the arduino board ...

In this project, we will show how you can build an ohmmeter using an arduino. An ohmmeter is a device that can measure resistance. Most of the times now, ohmmeters aren't standalone devices but appear as one of type of measuring device amongst many in a multimeter. An advanced multimeter, today, would have an ohmmeter, voltmeter, ammeter, capacitance meter, continuity tester, and possibly a temperature sens ...

In this project, we will build a liquid level gauge circuit with an arduino. This is a circuit in which a liquid level can be monitored through a gauge. We read the liquid level from the gauge (low, medium, or high), just as you see above. With a microcontroller such as the arduino, building this circuit is a pretty simple feat. The microcontroller can read the analog voltage from the liquid level sensor an ...

In this project, we are going to build a soil moisture sensor with an Arduino microcontroller. A soil moisture sensor, also called a hygrometer, measures the amount of moisture, or water, in the soil. Therefore, we can tell whether the soil has enough moisture or not. So it is a good diagnostic tool for caring for plants of all types. If the soil is extremely dry, then you will know the plant should be wate ...

In this project, we will go over how to build a night light circuit using an arduino. A night light circuit is a circuit which will turn on when nighttime comes, which is when it gets dark and the place could use some illumination. It is a common household device that is sold by pretty much all the major retailers. The device can sense when it gets dark and will switch on a light so that there can be some i ...

In this project, we will go over how to build a heat detector circuit using an Arduino. A heat detector circuit is a circuit, of course, which can detect the presence or absence of heat. This could be useful for a wide range of circuits including any device that needs monitoring and protection from excess heat. When excess heat is given to a circuit, maybe this could be dangerous for the circuit. Thus, if t ...

In this project, we are going to build a color sensor circuit with an Arduino microcontroller. A color sensor is a device that can detect and differentiate between certain primary colors. This sensor can detect and differentiate between the colors white, blue, green, and red. <p ">A color sensor is actually a very useful device. Now in the age where autonomous vehicles are being developed that can run ...

In this project, we will go over how to build a light detector circuit using an arduino. A light detector circuit is a circuit which can detect the presence or absence of light, depending on how we write our code to respond to the varying light levels. For example, if there is a great deal of light shining on our circuit, we can make anything that we want occur, such as have an LED light up. And we can do t ...
