This is the Pi T-Cobbler. It breaks out the GPIO pins from the Pi allowing us to connect cool stuff  Firmly press the cobbler into the breadboard making sure the first 5.0v pin is in H1 ## Steps ### Step 1 — Fitting the Cobbler This is the Pi T-Cobbler. It breaks out the GPIO pins from the Pi allowing us to connect cool stuff  Firmly press the cobbler into the breadboard making sure the first 5.0v pin is in H1 ### Step 2 — Fitting the ADC This IC (integrated circuit) is an analog to digital converter allowing us to read analog inputs into our Pi  Line up pin 1 (marked by a small indent on the plastic) with E27  Press firmly into the breadboard ### Step 3 — Fitting the knob This is a potentiometer. It will be our analog input.  Press it into the breadboard as shown with the first pin in A44 ### Step 4 — Wiring chip select Connect J12 to J33 using a yellow jumper wire This is our chip select line It tells the IC when it can send data MCP3008 CS/SHDN to Raspberry Pi CE0 ### Step 5 — Wiring Analog Input Connect C45 to C27 using a green jumper wire  This is our analog input ### Step 6 — Wiring data clock Connect J30 to B12 using a yellow jumper wire  This is our data clock, it allows the Pi to synchronize data transfer with the IC  MCP3008 CLK to Raspberry Pi SCLK ### Step 7 — Wiring MOSI Connect C10 to H30 using a green jumper wire  This is our MOSI (Master Output Slave Input)  It allows the Pi to talk to the IC  MCP3008 DIN to Raspberry Pi MOSI ### Step 8 — Wiring MISO Connect G31 to A11 using a blue jumper wire  This is out MISO (Master Input Slave Output)  It allows our IC to talk to the Pi  MCP3008 DOUT to Raspberry Pi MISO ### Step 9 — Wiring VDD Connect the RED power rail to I27 with a red jumper cable  This is providing power connection to our IC  MCP3008 VDD to Raspberry Pi 3.3V ### Step 10 — Wiring Vref Connect the RED power rail to I28 using a red jumper cable  This is our Vref  It provides a reference voltage to measure our analog input against MCP3008 VREF to Raspberry Pi 3.3V ### Step 11 — Wiring AGND Connect the BLUE power rail to G29 using a black jumper cable  This is our analog signal negative (ground or GND) connection to the IC MCP3008 AGND to Raspberry Pi GND ### Step 12 — Wiring IC Ground Connect G34 to the BLUE power rail with a black jumper cable  This is our negative (ground or GND) connection to the IC  MCP3008 DGND to Raspberry Pi GND ### Step 13 — Wiring negative to the knob Connect the BLUE power rail to B46 with a black jumper cable  This is our negative (GND) connection the the potentiometer ### Step 14 — Wiring positive to the knob Connect the RED power rail to B44 with a red jumper cable  This is our positive connection the the Potentiometer ### Step 15 — Wiring GND to the Pi Connect the BLUE power rail to A20 with a black jumper cable  This allows the raspberry Pi to share a ground (negative, GND) connection with the rest of our circuit ### Step 16 — Wiring 3V3 Connect the RED power rail to A1  This provides power to our circuit from the Pi --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
