Week 2: IR Sensor Circuits working

This week I was able to get the IR sensor circuits to work. Solder connection problems were resolved with more experience in soldering circuit boards. Noise problems were by decoupled the op amp power lines with 220 nF ceramic capacitors. I also replaced the female header pins with op amp mounts. It created stronger/more reliable connections for the 741 op amps and the rest of the circuit board. To create a signal between 1 and 5 volts corresponding to a distance of 3 to 8 ft from the beacon, I used variable resistors in the amplifier portions of the circuits. The IR sensor circuits ended up being a success. They did not break after repeated use and only had problems if the wire connections to the circuit board became loose.
