Concept
MINIBREAD presents a unique technique of learning and building basic electronic projects using mini circuit modules. All big electronic projects are made up of small circuit modules that easily fit on mini bread board. We show you how to build those small modules on mini breadboard and integrate those to build big projects.
MINIBREAD circuits have been designed keeping electronic amateurs and students in mind. The projects published on this site are very basic and easy to build. We don’t explain all the details of projects, but we explain the general circuit building procedures. However, we suggest important links where you can find the necessary details of each project.
Motivation
MINIBREAD is a new name given to LDR Engineering. In LDR Engineering, we first make a dark sensor and then add or remove some components in the circuit to make it functionally different than the previous one. In MINIBREAD also, most of the modules are tested using LDR and photodiode.
