Arduino Waveform Generator Shield
Waveform generators (also called function generators) are useful for testing and debugging circuits. They can be used to test the frequency response of electronic components like op amps and sensors or to characterize and troubleshoot audio effects boxes and pedals. This waveform generator shield is powered by an Arduino. It outputs four waveforms: sine, triangle, pulse, and saw, each waveform ranges in frequency from 1Hz-50 kHz. The frequency, pulse width, and overall amplitude (gain) of the waveforms is controlled by three potentiometers. Four indicator LEDs let you know which type of wave is currently being sent to the output. This Instructable describes how to put together the Arduino Waveform Generator Shield Kit I designed, if you’re interested you can also check out my original post about the Arduino Waveform Generator.
This Instructable will show you how to put the Waveform Generator Shield together, if you want a more detailed description of the circuit check out my Arduino Waveform Generator Instructable.
Solder two groups of 8 and two groups of 6 header pins to the PCB. Make sure to solder the header pins to the bottom of the board (the side that does not have any words). Here are some tips to keep the pins straight while soldering them down. The shield should fit nicely on an Arduino.
Step 2: Tact Switches
Press fit four tact buttons onto the side of the PCB, solder all four leads to the pads of the PCB.
Step 3: 8 Pin Socket
Solder one 8 pin socket to the part of the PCB labelled U2. Here are some tips for soldering the socket on straight.
