Sensors
This type of sensor uses sound waves to measure distance.
ultrasonic sensor
This device takes an electrical signal and makes something move.
actuator
To make an LED light up with your ESP8266, you need to connect one of the LED's legs to this pin on the ESP8266.
GND pin
What is the name of the software suite that enables the prototyping, deployment, and remote management of connected electronic devices at any scale?
Blynk
Name at least two TAs
1. Kalisimbi
2. Angel
3. Julius
4. Remy
This component is important to use with an LED to limit the current and prevent the LED from burning out.
resistor
An LED has two legs. This leg is the shorter one and should be connected to the Ground (GND) pin
Cathode
This is the part of the Arduino code where you set up your pins and connections.
void setup()
This is where you go in the Blynk app to add the controls for your project.
Developer Zone
How long is the CMU-Africa Bridge Program, and what is the time commitment per week?
Six weeks, with a time commitment of 10 hours per week.
If you touch something hot, this sensor acts like your sense of touch to detect the temperature.
DHT22 or DHT11
This type of actuator converts electrical energy into rotational motion.
motor
This function pauses the execution of your code for a specified amount of time.
delay()
Name two other platforms, besides Blynk, that are used for IoT development.
ThingSpeak, Adafruit IO, Cayenne, AWS IoT, Google Cloud IoT
What is one of the main goals of the bridge program in terms of skill development for students?
To develop academic, technical, and communication skills needed for success in graduate school and beyond.
What is the difference between a sensor and a smart sensor?
A smart sensor can process the data it collects and make decisions, while a regular sensor just detects and sends the raw data.
When you flip a light switch, this actuator inside the switch actually makes the connection.
Relay
What command in Arduino is used to set a pin as either an input or output?
pinMode()
This type of Blynk widget lets you turn an LED on and off from your phone.
Button
Which group project did the latest cohort work on during the bridge program?
Designing a sensor device capable of monitoring air pollution in real-time.
What's the name of the sensor that can detect movement, like when someone walks by
PIR sensor
I have three objects: a light bulb, a speaker, and a fan. Which one of these is NOT an actuator?
light bulb
Which Arduino function is used to write digital values to sensors?
digitalWrite()
How do you connect your ESP8266 to the Blynk platform?
Blynk library, Auth Token, and Wi-Fi credentials
How many universities are represented in the current bridge program?
1. Mount Kigali University
2. University of Kigali
3. University of Rwanda
4. African Leadership University
5. Adventist University of Central Africa
6. UNILAK
