Afterwards you can see that the hypno wheel start running at its minimum speed. Next, flip the power switch to its “on” position, and make sure that the onboard (D13) LED of Arduino Nano lights up for around 3 seconds. This hypno wheel is designed to run on a 9VDC supply, so you can use a rechargeable 9V battery as the power source.

Now everything should be ready to go, but first you have to learn how to operate the hypno wheel. I needed to use a few drops of super glue (rubber cement should work just as well) to mount the ~65mm diameter platter on the hub of the disc motor.

The hypno wheel part (the hypno disc) that I picked is in fact the platter of a defunct portable hard disc drive. However, if done again, I would likely try one hefty dc motor to drive another large hypno wheel to make a mighty electronic hypnotizer! At this point, note that the recommended operating voltage range of this particular torque up type dc motor is 1.5 – 6.0V, but it’s intentionally overdriven by a bit higher dc voltage in this project. Actually, it’s a low voltage dc motor which needs less than 50mA ‘no-load’ current to run well. The small dc motor I used in my breadboard prototype is a quite common CD/DVD disc motor (RF-300FA-12350) as it has a rigid hub to hold the optical disc, and allows an easy hypno wheel/disc attachment.

Be aware that this obviously calls for a suitable MOSFET or BJT based LED driver circuitry. Note that you can also use the D3 output to adjust the intensity of a couple of common LEDs if you want to illuminate the spinning wheel. I acknowledge that there are several ways to achieve better results with this project. If you prefer, go ahead and enter your own code. Needless to say, you are free to play with and edit this Arduino Sketch. Timeforspeedstep = millis() + (unsigned long)REG_INTERVAL If (!digitalRead(START_WHEEL_PIN)) setpoint = MAX_SPEED PinMode(LED_BUILTIN, OUTPUT) // D13 LED as “system start” indicatorĭigitalWrite(LED_BUILTIN, HIGH) // Turn on D13 LED during power up/resetĭigitalWrite(LED_BUILTIN,LOW) // Turn off D13 LED PinMode(START_WHEEL_PIN, INPUT_PULLUP) // Enable A3 internal pull-up #define REG_INTERVAL 10 // Interval between speed control steps (Now 10ms) #define MIN_SPEED 25 // Minimum Wheel Speed (Set this value 0 to turn the wheel off in standby mode) #define MAX_SPEED 250 // Maximum Wheel Speed (Highest Possible Value = 255) #define START_WHEEL_PIN A3 // Action Button I/P #define MOTOR_PIN 3 // Hypno Wheel Motor O/P Connect the Arduino board to your computer and upload the sketch. Now copy and paste the Arduino Sketch below into the Arduino IDE.
