What is an IR sensor?

IR sensor is an electronic device which measures infrared radiations and helps to detect obstacles and the motion in our surrounding. It mainly consists of a transmitter led and a receiver photodiode and detects infrared radiations having a wavelength from 700nm to 1mm emitted by the objects. When a specific positive voltage is applied across the transmitter led it transmits the IR rays. If these rays fall on some object then that object reflects back the IR rays which are received by the receiver diode. The receiver diode generates a voltage across its terminals which depend on the intensity of light reflected by the object. Generally, IR receiver led is darker whereas transmitter is transparent in color.

What are the IR1 and IR2 pins?

The ir1 and ir2 are the external interrupt pins used on the Arduino Uno. T, T1, and T2 are the variables to calculate the time. Since for this project we are placing the two IR sensors at a distance of 30 centimeters, therefore, we have taken distance as 30 to calculate speed.

Step 2: Floor Planning of the Electronics PCB Board

I started with the main control hardware which is the Raspberry Pi. The assumption here is that you already have a Raspberry Pi with the OS on it and have some Python coding experience. The Raspberry Pi controls the OPS241-A radar sensor and takes in the reported speed information.

Step 3: Mounting the Raspberry Pi

I mounted my Raspberry Pi to a perforated and plated PCB board using 4 spacers, screws, and nuts. I like to use a plated PCB board so that I can solder components and wires if need needed.

Step 4: LED Signal Level Shifters

The Raspberry Pi GPIOs can source a maximum of 3.3V each. However, the LED display requires 5V control signals. Therefore, I needed to design a simple, low-cost circuit to level-shift the Pi control signals from 3.3V to 5V. The circuit I used consists of 3 discrete FET transistors, 3 discrete resistors, and 3 integrated inverters.

Step 5: Large LED Seven-Segment Display

For displaying the speed I used two large LEDs that I found on SparkFun. They are 6.5" tall which should be readable from a good distance. To make them more readable, I used blue tape to cover the white background although black may provide more contrast.

Step 6: LED Driver Board

Each LED requires a serial shift register and latch for holding the control signals from the Raspberry Pi and driving the LED segments. SparkFun has a very good write-up for doing this here. The Raspberry Pi sends the serial data to the LED seven-segment displays and controls the latch timing.

Step 7: Mounting the OPS241-A Radar Module

The OPS241-A radar sensor is scrwed into a 3D printed mount a friend made for me. Alternatively I could have screwed it into the board directly. The radar sensor is mounted on the front side of the board next to the LEDs.

Step 8: Power and Signal Connections

There are two power sources for the sign. One is a converted HDD power supply which provides both 12V and 5V. The 7-segment display requires 12V for the LEDs and 5V signal levels. The converter board takes the 3.3V signals from the Raspberry Pi and level shifts them to 5V for the display as discussed above.

How to test a speed sensor on a golf cart?

Why does my golf cart stutter?

Your golf cart may move very slowly as if it’s creeping along or it may move at an erratic speed. You may experience stuttering in your golf cart like when you have a bad battery or there is a low voltage problem. A broken or damaged magnet on the motor can result in a bad speed sensor.

What happens if a cart sensor is bad?

If the sensor is bad, your cart will start rolling. Remember that if the switch is in Tow position, the cart will definitely roll. Ensure that the 3-pin plug from the sensor is connected and place a wire-piercing probe on the output green wire.

Why does my golf cart roll off?

Roll-away protection is essential for the safety of the golf cart. If the parking brake is not activated, the golf cart tends to roll off when it is in a neutral position and stopped in an incline. Please note that rolling will occur in neutral only at a predetermined speed.

Can a golf cart go fast?

Your golf cart may go fast initially and slow down drastically on its own after some time. This will happen repeatedly in a cyclic pattern. In such a situation, the car is said to be in limp-mode. You can do a roll-away test to check your golf cart speed sensor.
