The LM358 and LM324 are internally compensated operational amplifiers designed to provide stable unity gain performance. They offer 550kHz bandwidth at unity gain and consume only 0.5mA of supply current over their operating voltage range, making them well-suited for general purpose applications. The amplifiers can operate from single or dual supply voltages and have a common mode input range that includes ground with wide output swing.

The LM358 (dual), and LM324 (quad) are voltage feedback amplifiers that are internally frequency compensated to provide unity gain stability. At unity gain (G=1), these amplifiers offer 550kHz of bandwidth. They consume only 0.5mA of supply current over the entire power supply operating range.

The LM358, and LM324 are specifically designed to operate from single or dual supply voltages. The LM358, and LM324 offer a common mode voltage range that includes ground and a wide output voltage swing. The combination of low-power, high supply voltage range, and low supply current make these amplifiers well suited for many general purpose applications and as alternatives to several industry standard amplifiers on the market today.
The IR emitter used INF 5940 led with wavelength of 940nm and 35 angle beam The resistor for the emitter is 220 Ohms (for 9V) which gives me 35mA current (measured). For the detector I used INFD5940, which is basically the same led, but covered with dark plastic to absorb light better.
