Arduino My goal for this assignment is to create a Morse code decoder, which can prove highly beneficial for socially distant interactions with friends. The decoder will offer two input options for Morse code: (1) manual clicking of a button to illuminate the LED light, and (2) detecting flashes from an external source, such as […]

HW9 – Arduino The Task: In our Arduino project challenge, we were free to create anything of our liking, with the only requirement being that the circuit must either read a sensor or control an active component. During a class session, a practice example was demonstrated, involving a humidity sensor, LED, potentiometer, and LCD screen.

“We’re not like other semiconductor companies,” says Bob Dobkin, co-founder and CTO of Linear Technology, “for the most part we have a unique set of products because we combine circuit design, silicon design and testing.” Dobkin is an analogue legend having designed the industry’s first three-terminal adjustable voltage regulator, the first bipolar low-dropout regulator and

NXP has just released its new PMPB40SNA, a 60 V, 40 mΩ N-channel automotive MOSFET in a compact 2 x 2 mm DFN2020MD-6 (SOT1220) package. The DFN2020MD-6 is an industry first, featuring 100% wettable and therefore solderable flanks (side pads). This makes soldering and inspection much easier and is aligned with the automotive optical solder inspection requirements! It is the

The AD8232 is an integrated signal conditioning block for ECG and other biopotential measurement applications. It is designed to extract, amplify, and filter small biopotential signals in the presence of noisy conditions, such as those created by motion or remote electrode placement. This design allows for an ultralow power analog-to-digital converter (ADC) or an embedded

Description MAX44000 combines a wide-dynamic range ambient light sensor with an integrated infrared proximity sensor, making it a perfect solution for touch-screen portable devices. MAX44000 consumes as little as 11µA (time averaged) in ambient light sensing plus proximity sensing, including external IR LED current. The on-chip ambient light sensor is capable of wide dynamic range

For my first project with Particles’s Spark Core, I decided to make an internet-connected stuffed animal! After close consideration, I settled upon a blue and green alien to be the body of this project (see the above picture.) Powered by a Spark Core, this other-worldly being lights up and buzzes whenever my cousin receives an

A friend gave me one of Adafruit’s circuit playgrounds (developer edition) to use, and I wanted to see would it make a good robot controller. The circuit playground is packed full of features like sensors, neo-pixels and even an accelerometer. I wanted to add a L9110 motor controller and create a small bot I could
