Laser Gun Receiver
This is a simple laser gun target board that utilises a single servo, a twin 7-segment display, an LDR and an Arduino.
- Arduino Uno or compatible
- Stripboard cut to 24 by 24 holes
- Medium servo (slightly larger than the 9g servos)
- Light Dependent Resistor
- 2x 7-segment displays, common anode
- 10k Potentiometer with 0.1" pin pitch
- 9x 2-pin 0.1" pitch screw terminals
- 8x 150Ω to 330Ω resistors
- Hookup wires
- Do NOT refer to the schematic in the Fritzing file! It is NOT routed.
- The centre of the stripboard needs to be cut as per the Fritzing file. Make sure it is cut or short circuits will occur.
- Make sure that the Arduino's 5V power supply can adequately supply current for a servo
- Cut the stripboard to a size of 24x24 and populate the stripboard as shown in the Breadboard View of the Fritzing file
- Attach the servo as shown in the Fritzing file
- Solder extension wires to the LDR, install the LDR on your target board and connect the wires to the screw terminals as shown in the Fritzing file
- Hookup all other wires from the stripboard's screw terminals to the Arduino as shown in the Fritzing file
The Arduino code is compiled with the strictest compilation settings (-Wall) with no compilation warnings or errors and complies with the NASA C Style Guide (http://homepages.inf.ed.ac.uk/dts/pm/Papers/nasa-c-style.pdf)
