Please could someone assist me before I power the Intervalometer with confirmation of the Wiring and Transistor placement, As I am unsure from the website wiring diagrams.
I have attached 3 pictures:
- Website Wiring Diagram Screenshot.jpg
- Position 12 Photo.jpg
- Resistor position.jpg
1. I have all the wiring going to the Display Shield - Part = DI Robot Shield as specified from the Website - so no wiring to the Arduino.
Wiring Location Positions - Black Wires (one from the 2,5mm jack + one from the Battery):
2. The Black Cable in the top website diagram attached below is the main problem for me and appears different to the bottom website diagram.
Specifically:
- the top picture of the website diagram shows one Black wire coming from the PCBoard to a position on the right hand end of the Shield
- The website instructions - “The Black ground must be soldered to the pin on the far right of the second block” ??
- The new Shields are appear to have a different layout but are the same as the bottom picture of the website diagram?
- the bottom picture of the website diagram shows both Black wires (one from the 2,5mm jack + one from the Battery joined together) going to the 4th from left of the Pin positions Group that end with the "VIN" position where the Red wire goes
Please could someone assist:
3. Do both Black wires together (one from the 2,5mm jack + one from the Battery) go to the same position on the Shield??
4. if so, is this the 4th from left of the Pin positions Group that ends with the "VIN" position on the Shield where the Red wire goes
5. or is the PCB Black wire placed to a different position as per the top website picture diagram and if so, please could someone describe this specifically on the new shield and with a web photo?
Wiring Location Positions - Red Wire from PCBoard to Pin Position 12):
6. The website instructions require the Red Wire from PCBoard, connected to the Resistor, to be soldered to Pin Position 12 on the Shield.
The bottom website diagram reflects a Yellow cable, however this does not appear to go to Pin position 12, but rather to Pin position 6 (ie 7th from right)
The Schematic layout of the Shield below the Wiring Schematic in the website's bottom picture is more accurate and the 12th Pin position is 4th from left under the "ad" portion of the text on the Shield's writing of "Keypad"
I have attached a second photo (Position 12.jpg) of my Shield and soldering to what I see as Pin position 12 flowing up from the Arduino Shield P12 location into the Shield
Please could someone assist:
7. Have I wired the Red wire to the correct location for the Pin 12 position?
Transistor Placement:
8. Does it matter which way around the the Resistor is placed - I have used a NPN - BC337 with the thin Red band on the Resistor furtherest (left) with the larger Brown Band closest (right) to the incoming Red wire that goes to Pin 12.
I have attached a third photo (Resistor position.jpg) to show the Resistor, its colour banding and orientation on the PCBoard
Please could someone assist:
9. Have I correctly oriented the Resistor on the PCBoard?
Be grateful for your comments and assistance as I dont wish to have a puff of smoke.
Kind regards
