PCB Quality Control Almost every electronic device now a days is powered by one or more printed circuit boards (PCBs). Simply, we can say PCBs are the heart of electronic devices. Hence, the quality and reliability of PCB are directly correlated with the quality and reliability of the electronic device. For example, flaws in defining characteristics […]

We decided to construct a game for our final project for Microcomputer Architecture. The game, which we named Reflex is a simple player versus player reaction game in which the winner is rewarded with a drink of their choice, poured into a cup by a servo.  Flex sensors measure the reaction time of the players, […]

This project involved creating a red, blue, green (RGB) light emitting diode (LED) matrix that displayed the colors of the rainbow. The colors of the rainbow were chosen to show the full color spectrum that the LEDs are capable of, while still giving distinct variation within the LED matrix. In this project, each diagonal of […]

The goal of our project is to display the status of a previously implemented smart aquarium. The previously implemented system includes an external power supply, Arduino Uno, Ethernet Shield, ULN2803 driver, 4 120V AC relays, and 4 controlled 120V AC receptacles, and a servo motor feeding system. The four controlled receptacles supply power to three […]

In this DIY session, we make an Arduino Motor Driver Shield to drive DC motors, stepper motor and Servo Motor. Compatible with Arduino UNO and Arduino Mega, this motor driver shield can operate 4 DC motors or 1 stepper motor and 2 servo motors at a time. Here two L293D Motor Driver ICs are used for driving motors and an 8-bit […]

Record and Play 3D Printed Robotic Arm using Arduino Robotic Arms have proved themselves useful and more productive in many applications where speed, accuracy and safety is required. But to me, what’s more than that is these things are cool to look at when they work. I have always wished for a robotic arm that could help […]

Controlling Arduino with Raspberry Pi using pyFirmata Although Raspberry Pi and Arduino are two different hardware in terms of their applications and structure, but they both are considered as two competing open source hardware platforms. They both have very strong community and support. Today we will slightly change things, and show you how we can take advantage of […]

A datasheet-led 555 reference: trigger at a third and threshold at two-thirds of supply, monostable versus astable timing networks, and honest limits.

All embedded lovers are familiar with multimeter which a great tool to measure voltage, current, resistance etc. A multimeter can measure them easily. But sometimes we need to measure inductance and capacitance which is not possible with a normal multimeter. There are some special multimeters that can measure inductance and capacitance but they are costly. […]

Measuring the speed/rpm of a Vehicle or a motor has always been a fascinating project to try. In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Sensor module to measure the speed. There are other ways/sensors for this, like hall sensor to measure speed, but using an IR […]
