This component tester can test all of the passive components and most of the active components. Like- Resistor, capacitor, inductor, BJT, UJT, MOSFET, IGBT, diode and LED. Here I have made some tests ...

Chuck Todd has built a Arduino compatible Mega2560 expansion RAM that will enable those using the Arduino platform who need more that 8k RAM in the Arduino processor. Originally Todd created a ...

The same trick will probably work with any older Arduino boards you have laying around if Optiboot supports them. What can you do with the extra memory? Maybe speech recognition?

Developers, electronics engineers, makers and hobbyists looking for an affordable integrated circuit tester may be interested in this automated Arduino IC tester, created using an Arduino Mega ...

[Rafael] just made a little library that allows you to interface these modules to the Atmega328p-based Arduino UNO in order to gain some memory space.

Arduino Nano with ATmega328P is available in two variants: "ATmega328P" and the older "ATmega328P (Old Bootloader)". The newer variant uses an optimized bootloader which has double ...

Check out this Arduino-based electronic component tester. The device is intended to give a simple way to test transistors, resistors, capacitors, diodes and MOSFETs, and such like. The Arduino tester ...
