While the two posts are drying get the (2) 3″ PVC pipe blocker and place them back to back together and drill a 7/8″ hole in the center on both pieces at the same time, so you’ll have the center holes of both blocker matching each other and will make the motor support bracket level without any more adjustments to make. (see picture 12,13,14) Once both pieces assembled is time to paint them. Now we are going to work on the side posts (PVC pipes)that hold the motors support bracket.Ĭut (2) 2 1/2″ of 1/2″ PVC pipe, and place the 1/2 ” elbow on one side and the coupling on the other. Last drill two holes on both ends of the bracket (see picture 10,11) and cut the rest of the end of the bracket at the 3rd line across it. Next cut the bracket in half, and place on piece on top of each other and tape them together, it should measure 9″ from side to side (see picture 6,7,8,9). First bend the bracket 45* on the first line, then make a second 45* bend on the second line. Measure 1/2″ from the first line put a 2nd mark across, then make a 3rd line across 1/2″. Grab the nailed metal bridging bracket and put a line across on each end, right where the curved shape ends (see 1st picture). Step 4: Motors support bracket and side posts
Make sure you use electrical liquid tape or shrinking tube to cover the splices. Next cut (16) 12″ long of hook up wire, solder each wire to each potentiometer terminal, the LED and the switch. Next paint the panel and let it dry before installing the pots, LED and switch. Depending of what LED holder and switch you get.
You may have to check the drill bit size for the LED holder and switch.
This is the top piece of the enclosure.ĥ) Put the enclosure together, use the #6 x 3/4″ wood screws.Ħ) After the enclosure is been assembled, is time to sand and stain the enclosure. (pix 6) Step 3: Front PanelĬut a 14″ x 2 1/2 ” piece of the compressed wood, and drill 6 1/4″ holes for the pots. (See 4th picture)Ĥ) Cut a 13 1/8 x 2 1/2 piece, and drill two 1″ hole on each side. Start by cutting the six pieces that make the enclosure, the first piece would be the base (bottom piece).ġ) Grab the 11/32″, 2′ x 2′ Plywood sheet and cut a 14″ x 11″ piece.Ģ) Cut the side pieces, (see 2nd picture) for measurements.ģ) Cut a 13 1/8″ x 2″ piece, this is the back part of the enclosure.

Here Rx = Vx/I, by applying this circuit in Arduino, the voltage across R1 is VR1 = 5 – Vx, and then the current I = 5-Vx/R1, here R1, Rx are connected in series so the current flow through each resistors are same.Īrduino measures Voltage across Unknown Resistor using Internal ADC and performs calculations as per the code and gives unknown Resistor value.Ĭonnect +5V supply from Arduino board to unknown Resistor then connect another terminal to known Resistor (1KΩ) then ground the known Resistors another terminal. This simple schematic diagram has two Resistors called R1 (known value) and Rx (unknown value) by applying constant Vcc and then calculating Vx (Voltage across Rx) & I (Current) value will give the exact Resistance value of Rx. To know discrete Resistors Value, we use Color code technique or use Multimeter else we can use Arduino to calculate the Unknown Resistor value by using known Resistor, Voltage and Current flow.
