electro-labs.com published another great project based on Atmega328P: We are building another opensource SoloPCB project which is very enjoyable to build and use. In our electronics works, we frequently need to know the actual value of a capacitor. As you know, small sized SMD capacitors have no markings showing their values. Or there are lots of […]

Ken Boak has been working on an open source micro-solar inverter project: We wanted to make a design that uses readily obtainable N-type FETS and an Arduino (more strictly a ATmega328P-PU on a breadboard) to generate the PWM signals and provide simple circuit protection, and load sensing. With the PWM signals generated in firmware it […]

by Ardumotive_com @ instructables.com: Today I will show you how to make your own 7 segment – 2 digit – thermometer with Arduino uno and DS18B20 temperature sensor. I prefer to build my own arduino based circuit by using the ATmega328p uno possessor, but this is optional for you. You can also use breadboard to build […]
