1Hz to 30KHz Wave Generator Using Arduino
https://www.electronics-lab.com/1hz-30khz-wave-generator-using-arduino/
Wave generator is one of the most needed tools in our electronics labs, you can buy a fully functional ready made one or make a simple one using your Arduino. Joekutz over Hackaday.io created a simple wave generator using Arduino powered from 9V battery and produces amplified and non amplified signals. This generator uses the […]

How to control Arduino board using an Android phone
https://www.electronics-lab.com/control-arduino-board-using-android-phone/
Kerimil, user on Arduino Forum, submitted his project which focuses on establishing communication between an Arduino board and an android mobile using bluetooth: The idea is to gain access to hardware on Android devices (accelerometers, gyro, wifi connectivity, gps, GPRS, touchscreen, text to speech and speech to text) and/or use it to relay data to […]
Filtering Noisy Arduino Measurements
https://www.electronics-lab.com/filtering-noisy-arduino-measurements/
Paul Martinsen @ megunolink.com discuss about noise in analog input of arduino and how to filter it. He examines 3 filtering algorithms: Averaging, Running average, Exponential filter and provides the code to achieve that. Measurements from the real world often contain noise. Loosely speaking, noise is just the part of the signal you didn’t want. […]
DIY USB power bank from laptop battery
https://www.electronics-lab.com/diy-usb-power-bank-laptop-battery/
A DIY USB power bank made from an old laptop battery @ DoItYourselfGadgets: A situation many can relate to: an empty smartphone battery and no outlet around! That’s exactly why I recycled an old laptop battery into an USB power bank. This article will show you the basic powerbank circuit consisting of Lithium cell charging circuit, […]
Reverse Engineering a Simple Four Function Calculator: die decap
https://www.electronics-lab.com/reverse-engineering-simple-four-function-calculator-die-decap/
Electronupdate did a teardown and analysis of a cheap four function calculator: It’s such an amazingly old looking die. Even with 400x magnification it would not be too hard to reverse engineer back to a schematic! This must be a very old design indeed. When one thinks of high-tech it’s always the new-new thing… however […]

The Whoa Board makes things glow. It also makes glow-y things sense touch. It’s an open prototyping platform for wearable electronics! Turn any EL (Electro-Luminescient) material into a touch sensor with no additional hardware. It’s an open prototyping platform for wearable electronics! Open source and Arduino IDE compatible. Whoa Board: Dream With Touch Sensing EL Wire, […]
ElbSupply – Linear Bench Power Supply With Constant Current and Voltage Modes
https://www.electronics-lab.com/elbsupply-linear-bench-power-supply-constant-current-voltage-modes/
A lot of power supply designs are here and there on the Internet, but not all of them have constant current and voltage modes. You can read the following Q&A in electronics.stackexchange to learn what constant current and voltage modes mean. Elia over Hackaday.io built a linear bench power supply with the following features: Output […]
DIY USB to TTL Converter
https://www.electronics-lab.com/diy-usb-to-ttl-converter/
ams31 @ instructables.com show us how to build a DIY USB to TTL Converter using CH340G IC. Lots of USB to TTL modules are available in the market based on various chips like PL2303, FT232, CP2102 and CH340g. I have decided to use CH340g IC. Low costing clones of Arduino UNO & Arduino Nano also […]
