USB Ports, Plug In, Breadboard, Breakout board

Mounting T34 Polar Receiver

To begin, you will take your Polar T34 receiver (green chip) and mount it to your breadboard (red rectangle) as shown below. Make sure that you have made a connection before proceeding.

• Polar Heart Receiver

• Gently mount receiver to breadboard

Mounting Breakout Board

Next, you will then take your breakout board (connected to red USB) and mount it to the breadboard as shown below. Make sure that the Polar receiver GRD is directly across from your breakout board's GRD.

• Position breakout board

• Use your first wire to connect breakout board GRD to Polar Receiver GRD

Connecting Wires Horizontally

After mounting your Polar receiver and your breakout board, you will use your three wires to make connections horizontally.

• Take first wire and connect breakout board GRD to Polar receiver GRD.

• Take second wire and connect D+ of breakout board to the unit opposite the GRD end on the Polar receiver side of breadboard.

• Take last wire and connect the VCC of breakout board to the middle unit on Polar receiver.

• Take LED pin and place the longer side (neg) on GRD unit on breakout board side.
• Take short side (pos) of LED and add to D+ unit on breakout board side.

Make sure to double check that you have followed the steps above correctly and all connections have been made before proceeding to the next step.

Connecting Breakout Board USB

After setting up your breadboard, you will then need to connect your breakout board's USB. Take the USB connected to the breakout board and connect the opposite end of the cord into the top port of the MOD. Make sure you have securely connected your USB. After making this connection, you will then be ready to program heartbeat detection to your MOD!

• Connect USB from breakout board to MOD

• Red USB Goes Into Top Port of MOD
• Secure connection

Programming MOD

In order for your MOD device to detect heartbeat, you will need to program it with the sketch titled, "Heartbeat" (shown below). The black micro USB cord allows for you to program dildo.

• Power on your MOD, with its micro USB connected to your computer. A red light at the bottom of the dildo will turn on, signaling that it is charging and connected.
• MOD should respond accordingly. LED pin should light up in unison with the heartbeat being detected.
• If no heartbeat is detected, see the directions below in next heading to troubleshoot.

• In the Heartbeat below, click on "Run on Arduino."

Troubleshooting

If you are having issues detecting heartbeat with your MOD, there are a few things that might be causing this error.

1. SPIT ON IT. First, make sure you have good electrical contact. These sensors are made to be worn while sweaty, but if you haven't gotten reved up yet, you can just lick the back of the chest strap before you put it on. This is especially true if you are extra hairy like Andy (pictured).
2. Then begin by making sure that your Polar T34 receiver is close enough to the Polar T34 sensor to attain signal. If detection is still not acquired, proceed to the next step.

1. Look at the USB cords/ports and make sure that they are properly connected. While maneuvering your device, you may have accidentally disconnected your USB cords. Double check to see that they are properly fastened. If heartbeat detection is still not achieved, proceed to the step below.
2. Double check that you have properly setup your breadboard, breakout board, and Polar T34 receiver with the corresponding wires. Making sure that the correct connections were made to each piece as specified earlier in the "Setup" heading. Be sure to also check that a connection has actually been made with the wires, pressing down on the materials that we attached to the breadboard earlier. If heartbeat detection is still not achieved, proceed to the next step.
3. By this point, if you are still unable to detect heartbeat with your MOD device, double check that the Polar T34 Sensor is being worn properly. The transmitter should be worn flat against the chest, with the Polar logo in the upright position.
