Story In this sample, we’ll connect an 8-bit serial-in, parallel-out shift register to your Raspberry Pi 2 and create a simple app that uses the shift register to control eight LEDs. This is a headed sample, so please ensure that your device is in headed mode by running this command: setbootoption.exe headed (changing the headed/headless […]

Introduction In this sample, we will connect an RGB Controllable LED to a Raspberry Pi 2 and vary the intensity level of each color using a technique called Pulse Width Modulation (PWM). The ability to control the level of intensity of each of the three colors on the LED will allow us to make an

The aim of this project is automatically checking emails and showing the presence of new messages with different LED colors corresponding to different Gmail labels. The final product is a USB powered, WiFi connected, 3d printed small box with beautifully colored LEDs. You can place it anywhere there is a WiFi signal, and check your mailbox
Lights, Jumpers & the Resistance – Jumper wires are typically 22 gauge solid-core wires with insulation pre-stripped and readied for insertion in or out. Resistors resist the flow of electrical current, thereby controlling WHERE and HOW FAST it flows. [Thought experiment: If controlling water, using thin pipes would let less water through but would flow

If you are using your Raspberry Pi with Breadboard, and you have lots of connections to make, then the Pi Cobbler from Adafruit is pretty neat. However, sometimes you only need to make a couple of connections and the Cobbler is overkill and a few Male to Female jumper leads will do just fine. The

We designed Breadboard One as the first BitScope Ed project because it’s a simple mixed signal circuit which explains the key elements of modern mixed signal systems. A Mixed Signal Circuit is one which has both analog and digital components. In analog circuits the currents and voltages vary continously whereas in a digital circuits they

Arduino has multiple shields and multiple expansion boards, the shields make prototyping with the Arduino a lot easier. A lot of people design custom shields to match their requirements. But in a raspberry pi has a very few number of shields, and a raspberry pi is a powerful device at a cheaper cost and enables

This project shows how to construct a simple MCP3002 Analog-to-Digital Converter (ADC) circuit with a test potentiometer input. It shows how to wire the SPI pins for successful data communication between the ADC and the Raspberry Pi. Breadboard Build A breadboard, or “solderless breadboard”, is a tool, which allows engineers to rapidly prototype their circuit
