[IMSAI Guy] got some fake LM358 op-amps. Uncharacteristically, these chips actually performed well even though they didn’t act like LM358s. [IMSAI Guy] did a video about the fake chips and someone who ...

Here, we are designing a simple light activated switch circuit using LDR. It can be used in security applications like when there is darkness on the LDR, it stops lighting. The main principle of this ...

I have already made some devices using SeeedStudio’s Seeeduino Nano microcontroller boards and Grove Sensors. In this post I am going to show you how to make a simple sound activated electronic switch ...
