While the Arduino series of development boards have ease-of-use features that have made them a darling of the community, there are several situations where using them is not an advisable course of action for a project. Especially in projects where the developers desire a small form factor...

I have always believed that one of the best things about being a maker, is the ability to build your own tools, and we have covered the development of several tools like this in the past. For today's tutorial, we will add another tool to the list, as I will be sharing a guide on how you...

The circuit shown here is a compact and high-efficiency boost converter that has been designed for hand-held equipment. This boost converter converts 2 cells (3V) DC power into 5V DC with output load current up to 500mA. Typical efficiency when boosting battery inputs is 85%. The...

This Arduino shield helps to drive various loads like a solenoid, valve, motor, inductive actuator, heater, and bulb. A wide supply range 8V-60V and a load current of 2.7A allows it to be used with a variety of actuators. The board can be used as a stand-alone driver or it can be...

This sound sensor with Relay driver shield for Arduino Nano can be used to develop sound-activated ON/OFF switch or other projects that require sound senor. LM358 op-amp is used as the amplifier, 1st op-amp amplifies the microphone signal, and 2nd op-amp works as a half-bridge...

This is a simple power supply that provides an adjustable output voltage with an adjustable current limit. In such a small package, both these features make the power supply unique. The output voltage is adjustable range 1.2V to 6V DC and current limit range adjustable up to 1.5A,...

Network Attached Storage (NAS) are high-capacity storage devices that are connected to a local home or office network to provide everyone (with designated "clearance") on that network with access to the files on the drive without the need to plug into it directly. This facilitates things...

  This project consists of 20 non-contact infrared reflective sensors and each sensor provides an analog output. QRD114 sensor is the heart of the project which includes Infrared LED and photosensor.  The output of each sensor is high and goes low as objects or lines...
