In this project, we will learn how to control the brightness and colour of an RGB LED via I/O ports with PWM output capability, and a touch display sliders. The 4Duino resistive touch display is used as a means for a graphical interface to control the intensity and colour of the RGB LED. RGB LEDs […]
Real-world measurement requires the extraction of weak signals from noisy sources. High common-mode voltages are often present even in differential measurements. The usual approach to this problem is to use an op amp or an instrumentation amplifier and then perform some type of lowpass-filtering to reduce the background noise level. The problems with this traditional
Simple circuit provides precision ADC interface Continue Reading
In this project, we will control the angular position of the DC Servo Motor via an I/O port (with PWM output capability) and touch knob. The 4Duino resistive touch display is used as a means for a graphical interface to control the angular position of the Servo. Servo motor is a very useful device for
In this project, we will learn how to control the speed and direction of a DC motor via I/O ports with PWM output capability, a L293D quad half-h drivers IC and 4D Workshop widgets. In its simplest form, a DC motor has two wires which is connected to a power supply. Depend on whichever way
Home Security project is a password oriented security device. This uses 4Duino display as the user interface where the password can be entered. 4Duino is also used as the host device in this project. It handles a buzzer, an ultrasonic sensor, a uCAM-II and a magnetic switch. As a home security device, it sends an
BEAVERTON, Ore., March 15, 2016 /PRNewswire/ — Tektronix, Inc., the world’s leading manufacturer of oscilloscopes, today introduced the P7700 series of TriMode™ probes for use with Tektronix performance oscilloscopes. Offering up to 20 GHz bandwidth, the new probes ease the challenges designers face when debugging circuits found in the latest mobile and enterprise designs by minimizing
High-performance scope probes top out at 20 GHz Continue Reading
I wanted to probe a PCB at work to see how a ~500MHz differential clock was behaving. My trusty 100MHz oscilloscope was no use, it was too slow to see anything and unfortunately I couldn’t quite justify buying a $3k differential probe for my faster scope just for this. There are a bunch of DIY
An almost-GHz active differential oscilloscope probe Continue Reading
An AC (Air Conditioner) which was once considered to be a luxury item and was only to be found in big hotels, movie halls, restaurants etc… But, now almost everyone has a AC in our home to beat out the summer/winter and those who have it, worry about one common thing. That is their high

Have you worked with ready-made 8×8 LED matrix as displays? They come in various sizes and are quite interesting to work with. A large readily available size is around 60mm x 60mm. However, if you are looking for a much larger ready-made LED matrix, you may be out of luck. For this project, we will
Established companies and emerging start-ups are putting a stake in the Internet of Things ground, an opportunity with estimates of 50 billion devices connected by 2020. Standing in the way for many companies is the increasing complexity of technology inside connected devices. Shortened design cycles further fuel pressure felt by designers — the shelf-life of an IoT
