yes this from TV IR receiver module which i found from following website. https://circuitdigest.com/electronic-circuits/ir-transmitter-and-receiver-circuit to be honest i just noticed the upside-down configuration..and my receiver circuit does work fine without C1... thanks for highlighting the...

TSOP 38238 is an Active Low device , that is the reason i am using a PNP transistor for Q3

Ok let me explain, i made a circuit with only one Lm555cn, which did work but i didnt get a distance more than 3 meters. i added up a BC327 transistor on the out put of LM555 which increased the distance to 5.5 meters. in the distance of 5.5 meters my robot works fine.it detects the infrared...

Thanks for replying... Here is my receiving circuit i want to build a self charging robot which can detect its charging station and makes it way to the charging station... the receiver diagram showed above is just for understanding purpose. in real circuit i used LM324 comparator between Q3 and...

Hi, I made the following circuit for 38kHz infrared receiver TSOP38238 to increase the detection range above 10 meters. i was quite happy to see the range is more than 20 meters with TSAL 6100 LED. but i am facing a problem, my circuit works like a relay circuit. i have to wave my hand in...
