Simple electronics

If you have understood correctly, how to use transistors in circuits, you might have already conquered half of electronics and its principles. In this post we make an effort in […]

The circuit diagram of a simple electronic code lock is shown in figure. A 9-digit code number is used to operate the code lock.When power supply to the circuit is turned on, a positive pulse is applied to the RESET pin (pin 15) through capacitor C1. Thus, the first output terminal Q1 (pin 3) of the decade counter IC (CD 4017) will be high and all other outputs (Q2 to Q10) will be low. To shift the high state from Q1 to Q2, a positive pulse must be applied at the clock input terminal (pin…

I invented this super easy robot for kids just using paper and simple electronics. It can be upgraded with a remote control, solar power, and light-up anntennae! So you can start really basic and upgrade your robot step by step. This is a perfect DIY project for STEM or STEAM education. All you need is two geared solar motors, conductive tape, two button cells, and some cardboard and glue.

How to attach a Potentiometer to a micro:bit.

Introduction Generally a transformer is an electrical device or machine which inductively transfers the electrical power operating at a particular current and voltage of one circuit to the other circuit which is operating at different current and voltage level. Most of the transformers are manufactured such that their characteristics must match for special application requirements […]
