It is proposed to design an Adaptive flashlight so that the light intensity depends on the brightness environmental. When there is a lot of ambient light the flashlight is off and according...
I'm using the below circuit to build a auto dimming circuit. I was fine when I only use one 7-segment led, but when I connect more 7-segment led (parallel to L1) the light intensity is very low. How to make it brighter and function properly? Thank you.
Hello everyone, I'm new to these forums and hope to get some help. During the maintenance to a broken equipment, I could find that the error was a ldr of special design (not sensitive enough to respond to the stimulus of a laser). I have searched all the electronic stores that I know but they...
Hello
I am thinking of building the below circuit but i am short on components. I have all the others except SL100 transistor and BT44 triac which i can't seem to find in any local store. If anyone can tell me what alternative components i can use for these two then please let me know i would...
