Seeed Studio provided Zhihui with a complete service from PCBA prototyping, customization, and consignment services, bring the product from idea to market. This has led to an open-source, Linux Development Kit with SoM and Expansion Board that runs Ubuntu Core on a quad-core Allwinner...

Driving an AC high voltage and current load using an Infrared remote is very easy with this project. This is an open-source Arduino compatible hardware that is based on ATMEGA328 microcontroller, SSR (Solid-state Relay), Infrared Receiver TSOP1838, and analog input interface. We have...

LCR-Reader from Siborg Systems Inc. is an easy-to-use multimeter with automatic measurements. It offers a record high accuracy and unrivaled functionality. The device has reached the finals for Plant Engineering’s Product of the Year 2020 for Maintenance Tools and Equipment. Voting...

There has recently been a desire and surge in the development of standalone portable hardware development kits with qwerty keyboards and displays all fitted into a smartphone/blackberry-like (with trackpads) form factors, either for the sake of portability, or security and ease of use....

Monitoring the voltage level of a 12V Lead Acid Battery (SLA) is easy and simple with this project. The board is made using an ATMEGA328 micro-controller and 12 x 5mm LEDs. The ATMEGA328 microcontroller senses the analog voltage on A3 Analog pin and drives 12 LEDs connected to digital...

You may have seen many light-sensitive switch circuits based on an LDR sensor. Usually, the sensitivity of the LDR based light sensor is poor. We wanted a very sensitive light switch hence we decided to make a circuit based on a light sensor rather than LDR. After a little research on...

This isolated analog input module is useful for interfacing Analog signals of various types originating from analog sensors and field devices. The module is beneficial for in-process controls, factory automation, industrial applications, etc. Interfacing an analog voltage, an analog...

This pressure switch project is built using a piezoresistive transducer, LM358 OPAMP as comparator, and a relay. The circuit activate the relay when the pressure in a system exceed a given set-point. Basically, this switch can power ON or OFF a pump, valve, motor, when certain...
