This project demonstrates how to send data to ThingSpeak using a SIM800L breakout board. The data will be coming from a BMP085 atmospheric pressure sensor and will be using the SIM800L GPRS connection to publish this data to ThingSpeak.

I made this project because it seems a lot of people are having trouble with interfacing the SIM800L with an Arduino, particularly in connecting to a network. Here, I made a simple setup where I was able to display the signal level and the network status on an LCD. This …

This Arduino LiPo battery monitor and charger feature the TP4056 breakout board. The voltage level of the battery is displayed on a Nokia 3310/5110 LCD with the Arduino Nano as the microcontroller. Materials Arduino Nano TP4056 Breakout Board Nokia 3310/5100 LCD 3.7 V LiPo Battery Connecting Wires and Breadboard Introduction The …

This Arduino Altimeter project features the BMP085 atmospheric pressure sensor by Bosch. Because atmospheric pressure is directly related to altitude above sea level, we can use this sensor to determine current height with respect to the height of the oceans. The height is given in meters and is displayed on …

This Arduino motion-activated alarm features a tilt sensor for detecting movements and a piezo speaker for producing the siren sound. Introduction Basically, the tilt sensor produces a high voltage when it is tilted and a low voltage when it is placed flat on a surface. The siren is produced by …

This project is basically a remote-controlled car that is controllable via an application installed on a Bluetooth-equipped smartphone. Here's my version of a Bluetooth RC Car.

Project Overview I was recently commissioned to create a simple project for a coffee roasting machine. Basically, I need to measure the temperature of the machine in real time to monitor the progress of the roasting process. This includes a line graph that updates every second and is viewable on …
