So here we are, now we will see a very easy adjustable voltage power supply circuit which also has regulation, and guess what? We only need one transistor for making […]
Make this Automatic Street Light Circuit using one BC547 and Relay
Just a single transistor, an LDR, a few resistors, and a relay could all be used to create a somewhat useful automated street light, as seen in the diagram below. […]
Auto Cut-off Battery Charger Circuit using One Transistor
The inexpensive battery charger circuit with only one transistor is intended to cut off the battery’s supply immediately when it reaches its maximum charge level. This article describes a very […]
