In my case I have used only 3 x 330Ω resistors, 3 leds and a TSOP4838 IR receiver module. ... Arduino IR Remote Control Schematic. Arduino Sketch ... I created this website and I want to invite you to ...

Below is the schematic we created in EAGLE and a parts list. T1, T2: 2N3904 transistors; T3: ... My whole circuit is 2 resistors, 2 LEDs, the phototransistor and the ATTINY45.
